Absolutely not required. If you want PhysX you will be fine with the 770.

Paradox Personified posted:So, confirm/deny; "physx really requires a second card to look nice"? To simplify, PhysX is a physics API that can either run (non-proprietary) entirely on the CPU with less advanced stuff, or run (only on nVidia cards) with GPU acceleration. In the latter role, it's a lightweight CUDA workload. In practice, accelerated PhysX on the same card that is rendering, even in SLI situations, can be such a weird mix-up of roles that it can impact framerates negatively compared to using the off card solely as a PhysX co-processor. The most advanced PhysX games around right now still only bring a 650Ti (which is my personal PhysX card) up to about 21% GPU usage, but there's something in the way that role-juggling - that is, the shifting between shader operations as SM/SMX units vs. acting as CUDA cores and all the timing/coherency stuff involved for GPU-accelerated PhysX - that just bogs it all down. Accelerated PhysX can be offloaded to a headless coprocessor which never has to switch roles at all and can devote its entire operation strictly to the task of CUDA physics calculations. With that happening, there's no juggling on the rendering card and so it's generally a better experience. This was true as of the GTX 680, but it's possible that the GTX 780 and above just have a shitload of CUDA cores to spare and might perform better - certainly one would hope that the Titan would do a good job given its GPGPU aims - but I have still found that in practice I can enjoy a really full PhysX experience in the games that support it by offloading the work to my 650Ti, whereas if I try to run the same stuff on the GTX 780 alone, framerate takes a pretty big hit, especially minimum framerates (seems like there's a bottleneck somewhere there, I'd conjecture involving the timing of the physics lining up with the rendering operations). If you're using AMD hardware, I don't think there are any currently working hacks to get PhysX available to AMD cards. There are other more generalist GPGPU physics solutions like Bullet Physics, and there are plenty of physics APIs that are CPU only and look great (hell, PhysX's CPU-only version looks great). I don't think PhysX has a lot of staying power. In fact I hope it doesn't. Among the many limitations of a proprietary physics getup, you can't do both SLI and PhysX at the same time, and given AMD's recent advances in using PCI-e 2.0 8x+ bandwidth alone rather than requiring a bridge for dual GPU rendering, and coming UHD display resolutions, I think it's better to put the coprocessor to rest entirely.

Kaddish posted:Whelp. I broke and bought a 780 today. I've been thinking about getting something with more than 2GB anyway and the price difference between a 770 4GB didn't seem worth it. Anyone want a just fine for everyone who isn't crazy 660 ti? Does your board have more than 1 or 2 PCI-E slots, and do you have a PSU that can handle a second card? Toss that 660Ti in and dedicate tp PhysX processing, see if it helps with some games. Lots of folks here have been doing that, but if not, you can probably get some decent scratch for it selling on SA Mart or something. Tgent posted:I've had a look around and it seems that's likely. Unfortunately there doesn't seem to be any way to stop it apart from stopping windows from getting any new hardware drivers at all. Set Windows Update to download the drivers, but to NOT install them right away. I've done that for a while now because of some driver issues, and other updates I didn't want or need auto-installing without my choosing. I keep it that way so I get a notice of the updates, but can still choose what to install versus having everything install automatically and bork something up.

Paradox Personified posted:Thanks for taking time on me. At the very least, it's nice to have someone watch me flail like a chicken with its head cut off. You can't use hardware PhysX (the fancy PhysX that's in like 30 games, total) without an nVidia card. nVidia is the company that makes the Geforce GTX cards. AMD is the other company, they make the Radeon HD and, recently, the R9 290x and related cards. If you want PhysX for some reason, you need an nVidia card. If you want really fancy PhysX at very high framerates, you may need a PhysX card on its own, too. But if you don't care about that poo poo, then you don't have to worry about getting an nVidia card for any other reason than price:performance. And right now, AMD and nVidia are both slugging it out with regards to price:performance. If GPU-accelerated PhysX is not a concern, then your only concerns become what card to get that'll perform well at the resolution you're playing at. I'm guessing you don't know or care about TrueAudio or Mantle or Shadowplay or any of the other various proprietary technologies, either, so just get a good fast card for the resolution you want. That advice can be obtained in the parts picking thread. Have fun!

You don't get that option on any version of Windows that's still worth installing. That screencap's from Windows 8.1, and there's an extra auto-install for new devices only option back in Windows 7 - which is still not great. I'd go one further and say that when you're doing a fresh install of Windows you should turn it off entirely before it ever sees the Internet. If it's really such a big deal it'll show up in Windows Update - and given nVidia's issues with Fermi and intel's old (by old I mean 4500MHD days; hopefully it's gone now) habit of making their WU integrated drivers incapable of being updated by their Download Center integrated drivers at a later date, I'd hide driver updates even there. If you see one, go to the driver's actual source (nVidia or Intel, not eVGA or Dell or whatever unless specified by name) for the update, if there's not a massive rash of problems reported with your device on the new driver. dont be mean to me fucked around with this message at 22:10 on Nov 3, 2013 |

Ruin Completely posted:My 7850 can hit 1.2ghz with no problem, but when I tried to OC the memory poo poo crashed, I hope that doesn't prevent any worthwhile performance gains. It shouldn't be too bandwidth bound, you can try running some benchmark at 1100/1150/1175/1200 and see if the scalling falls off too much for your liking. Not sure why the hype about TXAA was a thing, from the screenshots it had the blurred out look of FXAA with a performance hit worse than MSAA. It might have worked better in motion, but I guess I don't hate jaggies enough to put up with vaseline-o-vision

Guni posted:I don't think I've ever experienced screen tearing, thank gently caress. All this talk of new GPU's is making me wanna upgrade though. I've noticed that 7990's are like $700, are they a decent product [in terms of overall quality/usability etc], which brings me to another point, is AMD still having the crossfire issues? Note that if you're totally crazy and weren't going to be satisfied with just two GPUs, it is pretty much impossible to crossfire two 7990s - the top left of four GPUs will reach unacceptable temperatures in any config and is nearly impossible to get running stable unless you rig up a side fan with a duct or something. I haven't tried it, just came across some stuff in my research, so that's one reason to consider SLI 780s or 290Xes or something, especially since you could potentially use three of them

I played for exactly 1 game yesterday with the fan uncapped. After that it got back to the 55% auto setting. With my house only being around 70F the card starts throttling itself around 800mhz if it is only allowed to spin up to 55%. When it was allowed to spin to 100% it ran full 1000mhz but would sit at 80% fan and run up to 100% during more intense battles. That being said, 80% is loud as poo poo, 100% is purely unacceptable. But then again I've been spoiled with the silence of watercooling for about 5 years at this point.

Is buying a PCI-E 6 pin to 8 pin adapter literally the stupidest thing I could do? I have a Corsair 520 PSU that has one 8 pin (6+2) and one 6 pin connector but I'm looking at one of the Sapphire Vapor x R9 280s and these appear to require two 8 pin connectors amd I'm not keen on replacing the PSU just for that. On the other hand I'm not keen on it blowing up either. Edit: Hmm, seems it actually needs a 6pin and an 8 pin for non-crossfire and it comes with a two 6 pin to 8 pin converter. Also, the PSU actually only has two 6 pin connectors so I either need to use a 6 pin to 8 pin converter or a two molex to 8 pin. gently caress, this is what I get for keeping the same PSU for 6 years! Edit 2: Nevermind, opened the case to check and it does actually have 2x6+2 connectors already. Sapphire's website quotes a 750W PSU as being needed  Is that just a hedge against someone trying to put a card in with a no-name 500W PSU and burning their house down?

Hmm, I just bought an Open Box GTX 770 from Microcenter to try out, when I install it the fans spin but no signal to the monitor. I can still plug the HDMI straight into the motherboard to see, and trying to install new Nvidia drivers says that no graphics cards are found. Do you think I actually bought a brick, or am I screwing something up? I have it wired in exactly the same as the 660ti I just yanked out.

Had that same issue with a Gigabyte GTX570. It was as if the card didn't exist, it wasn't even in the BIOS PCI-E config as there. A couple restarts and it eventually triggered the windows driver installer, and after having that run it sorted itself. It was definitely strange.

I have a Dell T7600 with PCI slots above and below the CPUs. When I try to jam dual GPUs on one side I have heat problems as the cards are adjacent and if I put them on either side of the CPUs the SLI bridge connectors are ~11.5" apart. I have looked all over for custom length SLI bridge connectors and the people that I can find that used to make them seem to have disappeared. Anyone have a source for very long ~12" or custom length SLI bridge connectors?

The R290 seems to be the card that makes the most sense at the $399+ assuming the non-reference models come out before December. With the OC that Anandtech managed, it puts some real daylight between itself and a Titan in a lot of tests. At ~$450 for custom card, it will likely make the upcoming 780Ti rather unattractive for gaming with its 699 price tag.

Not sure if my perspective is skewed but 400 is still a little on the high end in terms of what people (at least do-it-yourselfers) consider for gaming PCs. How many 800 or 1000 USD builds are there out there compared to, say, $1500 or $2000 builds?
