If I could trade in my computer spending over the last 5 years, my bug would be rust free, painted, on air ride, and have a 200hp engine in it. Yay for computers. Here, have this thought for a new page.

veedubfreak posted:At this point, I still do it simply for how quiet it is. I have my fans on at roughly the minimum voltage to make them spin. When you have 2 cards, the cpu and mb all on the same loop with 4 360mm rads it's almost passive. This is the setup I need to get to, especially with the tuned-down fans. Mine still sounds like Twister when I first boot it up, even with the fan control unit hooked in.

My long-term computer goal is to build a loop with enough rads and big reservoirs to run a full system passively (with -E series CPU and two GPUs no less). I would have no reservations about running GPUs at air cooling temps if it could be fully passive. Every time I save the money to do it I end up spending it all in a different area, like my car or a holiday.

Having just thrown a G10 on my 980, I can say that doing that is a bit overkill. I have a massively overclocked 2500k on a (reasonably large) air cooler that runs at all of <600RPM and is effectively silent, paired with a H110 on the 980, which after routing the fans for that through a manual fan control unit, are also pretty damned quiet. The loudest part of my computer is the pair of 140mm fans I have for general "everything else" cooling, and they barely run at all. The advantage I see of an AIO + G10 (other than ease of maintenance) is that when Pascal or Arctic Islands comes out, there's a pretty good chance I'll be able to port it right over, without having to bother spending another $100 on a new waterblock. Also it didn't cost me $300+ for the initial setup.

Yes, radiators do use copper. So do heatsink base plates, and waterblocks, because it conducts heat well. I therefore ask you, what is the value of removing heat from a computer, only to radiate it back into the room through the copper pipes, before it can get to the giant radiator they mounted outdoors that it needed to go to? Had they used something less thermally conductive, or heck, wrapped insulation around the piping, the heat might have actually gotten to where it needed to go, and not just gone back into the room they were trying to get it out of. (Even then mounted right up against the wall, they wouldn't have been able to wrap the pipes in insulation. It comes in long lengths, and looks like that piece of foam that would wrap around the crotch-busting bar on your first bicycle.)

I really doubt those pipes are radiating much heat at all. Water moves so fast through those systems it barely heats much over ambient.

Well what do giant data crunch centers use for heat dissipation? I would guess something diluted in water to increase boiling point and the amount of energy it can transport. And I assume they use water because it can potentially hold a poo poo ton of energy before phase changing. I also assume they'd insulate the transport (pipes) where needed.

Even if this is true (and I'm not convinced that it is--there looks to be 10-20' of piping for each computer, which is pretty significant; I'm not going to bother doing the math, but I wouldn't be surprised if 20' of 1/2" pipe had effective surface area comparable to a 120-240 radiator), the whole thing would have made more sense with something like insulated PVC pipe, which would have not only made installation easier, but been a whole lot cheaper, too. I guess maybe they just really liked the aesthetic?

I built a new rig earlier this year after several parts completely shat themselves, but couldn't afford to also replace my old HD7700. Right now I've got a bit of scratch I can put towards a new GPU, so I picked up a new R9 380 for €240,- All's well that ends well, right? Except it turns out there's an issue with AMD's drivers with playing some games (specifically, FFXIV, which is my main pc game these days) for the R380 cards. poo poo. I'm probably going to return the card, but I'm not really sure what to replace it with. R9 290 used, ~€170-€190 GTX 970 new, ~€350 GTX 970 used, ~€300 GTX 960 4G new, ~€250 It feels a bit silly to get the 290 at this point/price, but I'm not certain if going up a notch to the 970 is worth it since it'd be kinda stretching my finances. I never hear poo poo about the 960, which seems like the closest Nvidia equivalent to the R380. Also I'm a bit wary of buying hardware used.. help?

If you can get the 970 you should, it will give you 60+ FPS in FFXIV at max settings @1080p very consistently. If you get a used 970 or 290 get one of the brands that offers transferable warranties.

Considering the price difference between those the used 290 is clearly the better option if you are comfortable with a used card. Unless it's the reference style blower cooler. The 960 4gb is never worth it.

Errr I dunno, it is almost exactly how a water based heater works. I saw that video and was cringing, they were turning that room into a gigantic heater. Fortunately the insulation thing would work perfectly fine and would be very cheap, although considering the length of pipe involved it would cause more work for the final radiator (so if it was already at 100%, the overall temps would increase for the equipment involved) xthetenth posted:The 960 is never worth it, the 2 GB is already starting to tank. Interesting info I saw yesterday, nvidia is increasing 960's to 4gb reference. Personally not sure how much that's going to matter for that card but I guess they've taken notice to the grumbling. edit: Well drat, you've got me interested again. I used to be very vocal, especially in the last two gens and with nvidia in particular, about the snake oil that was doubling vram over reference. It boiled down to cards that shipped with 2gb (3gb, etc) simply did not benefit from twice the ram because then everything else become the bottleneck before you could even use any of it. However, this was just as dependent on games and the technologies they used as well. As some pointed out you could easily fill the vram buffer while having a fairly low GPU load - in theory. Reality at the time was that simply never happened in anything even close to playable framerates and focusing on vram was a (successful) marketing scam. Also since AMD vs Nvidia is so much more popular these days I should mention AMD was significantly superior in memory handling than Nvidia during the 600-700 series era and it was never the bottleneck for them, but they had the same basic conclusion: dont buy twice the vram over reference. But times change, and I wonder if there's something to it now. Are developers using more vram in proportion to GPU processing than they were before? Is nvidia doubling the vram purely in response to negative views about the card in general or is there an actual performance reason?   Hmmm, looking depressingly familiar so far but wait!   Holy poo poo a real difference! Those spikes in particular are often what is seen as a "laggy" experience. Its how a "smooth" 30 fps can look so dramatically different than a "laggy" 30 fps. And, in this case, we are talking about 1440p at around 30 fps. So for the first time in YEARS I've seen a card that appears to have some real benefit from doubling the vram over reference. 30 fps is a playable fps (a huge caveat in the past) especially for a singleplayer game. But would I recommend spending more for a 4gb 960? I'm not sure*. This no longer seems to be an issue if you play at resolutions you'd expect to play with a 960. But I can probably say nvidia officially doubling the vram could be for more than simple marketing reasons. Edit2: After actually looking at this post I probably put a more positive spin on the concept than I meant to. I am excited to finally to see some difference here at a somewhat reasonable resolution and framerate. In the past this used to be something fiercely argued, here and in particular the internet. And friends. And store employees. And the very companies spreading misinformation. Some random guy at work who bought a 6gb 280x because well, its got twice the ram! I am really not trying to push people to buy a 4gb 960 here is all I mean. The graph above is playing a game at 1440p with a 960, not something I'd ever recommend anyway. *no just buy a 970 at that point lol penus penus penus fucked around with this message at 18:41 on Oct 10, 2015 |

Been out of the loop on GPUs for awhile. I have a buddy looking to do video editing so general GPU/CUDA is the big need. He's currently looking at the 970. Good? Bad? Any other suggestions in the $200 price range?

This sort of depends on if you actually have to pay significantly more for a 4GB card verses a 2GB one. I was able to find a significant price difference going from 2GB to 4GB for the 960, $189.99 vs $229.99 for the MSI models. But when I looked at the 380: Sapphire R9 380 2GB: $194.99, Sapphire R9 380 4GB: $204.99 So yeah, not worth it on the 960 but probably well worth it on the 380.

I think it'd be smart if they kept it at the 2gb pricepoint - it'd certainly be in line with the rest of their behavior this year. I actually didn't realize 380's came with 2gb... since 280's came with 3gb lol. That's just... well, anyway, I'd say well worth the $10.

Different VRAM bus width, the 7950/7970 (280/280X) used a 384-bit bus, whereas the 285(380) is a different chip entirely and uses a 256-bit bus with colour compression to make up some of the deficit. I agree they should have never gone out of the door with 2GiB VRAM, though.

Yeah, I was talking about situations where you are actually fighting stuff, well, outside of over crowded FATEs at least. Though I get pretty good numbers in Foundation, like 58-70 FPS even near the crystal or at the bazaar, maybe because I have an i7-4790k?
