Purgatory Glory posted:Wow, I clicked purchase expecting to be taken to a link calling me a gullible retard. Instead it really asked me for $159.00 for 3 aquarium rocks in a bag. Machina Dynamica started as a joke, but people started sending them money. It's much more obviously a joke now with products like this -- but check out some of their earliest pages in the Wayback Machine. To provide context, isolation platforms for speaker cable are actually a thing audiophiles buy. The theory being that your cables being on the ground increases microphonics from vibrations and increases the capacitive effect of the insulation. You can find tons of testimonials about how much of a difference these make at the margins! I am actually having a ton of trouble trying to find a place that sells these, but you can see a picture of what I'm talking about here:  Audiophiles go through fads, and around the time Machina Dynamica popped up these were super popular -- and on the theory that more expensive is better -- sites respected by the community were absolutely selling versions of these for $100+ each. EDIT: Linked the wrong product, having trouble finding the exact one I am thinking of -- which were platforms for just the cables and not your entire rig. Isolation platforms are definitely still a thing people buy -- mainly for vinyl. You can easily spend thousands on these, with some fancy ones based on extreemly strong magnets and ferrofluids. Meanwhile -- research scientists that need to isolate highly sensitive equipment from vibrations use platforms floating in pits of sand. A $20 solution.

https://www.pugetsystems.com/labs/articles/Thermal-Paste-Application-Techniques-170/ I think thermal paste voodoo is the closest thing we have to random-rear end pseudoscience. I love how the author tries 20 different patterns and insists on a best one, even though his own chart shows that they're pretty much all the same.

INTJ Mastermind posted:https://www.pugetsystems.com/labs/articles/Thermal-Paste-Application-Techniques-170/  A 2C difference under load simply from using a different pattern of the same paste seems reasonable enough. I mean, people chase similar gains when arguing about various coolers. At least it's something that can be actually measured empirically.

I've always done smooth spread myself probably based off of advice I got in 1998. So it's good to see that it's still effective. I did have an Athlon XP that scorched through the thermal pad and ran bare metal on metal for what could have been years as far as I could know, on an ECS board, no less. The takeaway I got from that is the spread probably isn't so important, so long as the HSF is on there tight enough. And to never trust the pad on a stock fan if it's got one. It's been all Ceramique for me from that point on for both GPUs and CPUs.

Just to prove that it's really difficult to gently caress up thermal paste...when my sophomore roommate was building his first custom computer, he spread out Radio Shack-branded thermal paste onto the bottom of his HSF assembly *with his unwashed finger*, adding none to the CPU. He later had to redo it and did it properly...and he got better temps with the finger-spread Radio Shack paste than he did doing it 'properly' the second time with Arctic Silver.

Also, paste application is CPU dependent, according to Arctic Silver, anyway.

It wasn't that long ago that image quality mattered, like the generation before one of 'em (brain's telling me AMD) ripped off the other one's AF algorithm more or less entirely and it's been pretty neck and neck since then. Both of them have solid AA tech, no real difference there anymore apart from the details. Nobody seems to care about AA anymore, though, it must all be good enough now that resolutions are getting higher for enthusiasts at least and perf is better carved out of other stuff. I'm really out of the loop on all this crap now, I still like my 780Ti and I haven't even played the witcher 3 since it came out and my preorder turned into a game. I have however beat Crimsonland and also Red Nation on my laptop, which has a GTX 540m in it and overheats regularly. The point is, buy AMD

Intel could fix this simply by putting a thin plastic cover over their heat spreader-covered CPUs that demarcate exactly where the core rests beneath it. Covering the *entire* spreader plate isn't necessary, since the bulk of what needs to be cooled will be in that area. Hell, even just a picture that shows where the actual die rests on the chip without the spreader would be enough. Vertical/horizontal probably indicates which 'direction' the rectangular die rests on the chip, latitudinal or longitudinal. And seeing as this is Haswell without a heatspreader, I can see where you'd want to follow along the line of the die:

Isn't the point of a heat spreader to spread the heat? So you'll need to cool everywhere not just over the core.

cat doter posted:I'm sure the difference between a horizontal and vertical pattern are very thermally significant For a non-square die, potentially yes. The PDFs linked on the Arctic Silver page actually show this pretty well by showing what the die looks like under the heatspreader and the area you want the compound to spread out over for ideal performance. If you do it opposite to the direction of the die you might not fully cover the important area. For a GPU or older/mobile CPU without a heatspreader patterns don't really come in to play, you want to actually spread the compound on the die as thinly as possible while still covering the entire thing. Thermal paste is only there to fill microscopic gaps, you don't need much of it to be effective as long as it covers the appropriate area.

Both of them have solid AA tech, no real difference there anymore apart from the details. Baseline AA is cheap and getting fancy isn't worth the cost at higher resolutions, especially now that monitors with higher DPI are coming out that really diminish the effects of aliasing.

At 2GB the 960 is alright but it's not really seeing any improvements at 4GB because of the low memory bandwidth so it makes sense to pick the 380 every time.

The 960 shows very real improvements from the 4GB framebuffer. Taking into account delta compression and the different clockspeeds, the real world bandwidth difference between the 960 and 285 is incredibly minor.

The 280x is still an option around $200. Quick googles shows you can get them around 190 to 220 bucks after MIR. It handily beats the 969 from the benchmarks I've seen.

Your link has like six fps at best. It's mostly margin of error. I am not sure I'd bother, with other more powerful cards around the same price point.
