Well that didn’t take long. Over at Guru3D they took a pair of the new GTX580’s and put them through the wringer in SLI configuration, with screaming results. With such amazing performance in 1 card, two cards winds up bottlenecking the CPU which can’t feed them fast enough. When all is said and done, what’s the result? Well, first off you’re gonna need some serious wattage to pull this off:
Power consumption then, well it is high. When observing Crysis Warhead, which really is tremendously GPU intense, we notice power draws well over the 700+ Watt. You do need to be aware of that, each GPU has a 242W TDP, that’s nearing 500 Watt already. Then add a nice spicy processor, likely overclocked a little drawing say 175W~200W and then the residuals like chipset and devices really can accumulate to significant numbers. But hey, this is the extreme high-end arena, it never has been any different. It’s just that over the past years we as consumers and press have become much more critical about this topic.
In addition, if you want to go triple-screen stereo then you’ll need the two cards in SLI configuration. But if you’ve got the cash and the power, it’s phenomenal performance.
