Summary: 4GB version GTX680 for £405 including postage which is a very reasonable price indeed. Arrived quickly, well packaged and no problems after 2 weeks of heavy gaming. Cons - The reference design stock cooling is tremendously noisy at 80%+ fan speed.
Summary: I bought this for a new build. I'm a Mac person unused to building PCs and I was nervous in case I damaged the card in the build process. But it's powerful and perfect for the gaming and development machine I've constructed. Not noisy.
Summary: I've purchased two of these now and put them in SLI and these are the cheapest 680s I could find. Although they have the reference design, with a slightly adjusted fan profile they reach max load temperature of 65 degrees in furmark and are around 30 degrees at idle. They both have boost clocks slightly above the stated boost clock and can max out most games at 2560x1440 with 60fps (as 2 680s should).
Summary: Simple to install and provides high performance graphics with excellent management of power consumption and noise. I bought this as my second GTX680 on a new build. I can't honestly say that the extra on card graphics memory has made a noticeable performance difference, but as it didn't cost any more it sure hasn't done any harm. All of the usual GTX680 benefits to which the many online reviews refer.
Summary: Okay, so I upgraded from a GT 640 to a Palit GTX 680 and of course it was a huge upgrade. Even tho I can run BF3 70+ fps and black ops 2 150-200 fps I'm still a bit disappointed. I play WoW with 240fps in arenas but in stormwind i get from 30-80 fps only. This is on ultra settings. This is of course good but the problem is that my friend has an Radeon 7850 and gets around the same fps as I do on most games.
Summary: I received the first Palit revision of this card based on Nvidias reference card, however the performance is excellent regardless with operating temps varying from 26 idle to 82 while stress testing (99% load using FurMark), typically heating to ~68 degrees under reasonably GPU intensive games (Battlefield 3 / Metro 2033).
Summary: I've had a great time using factory overclocked cards in the past. I figure that if they come with extra power connectors and custom coolers, then they're more likely to be stable than anything I could do myself with a stock card. After two years with a Palit Sonic Platinum GTX 460 I thought I'd go with the same company again, and I'm very glad I did.
Summary: performance is breathtaking, triple fans keep it cool under heavy loads. pretty quiet, too. overall, very good addition if you have a fast system and want to make it even better. (if you don't already have a fast system, sort that out first, otherwise the PC will be struggling while the graphics card sits waiting.
