@Leochan - Nice. So basically it's pretty much a dual 570 with a larger frame buffer, at least in terms of performance?

I think it's VERY competitive with the 6990, as you said it's more efficient and quieter, and beats the 6990 in 5 of 12 benchmarks (so not half, but close), and does so at the same price with the added benefits of 3D Vision, 3D Surround, and CUDA eh? NvIDIA is clearly trying to be more price-competitive these days.

Would have liked to have this (I have dual 570s).

BTW: Bit of a typo on the conclusions page:

Also, the performance of the GTX 570 essentially matches dual GTX 570 graphics cards, but with the GTX 590 you get that performance level on a single PCB along with a lower TDP.

As long as you don't plan on tweaking the voltages and are limited to a single pci slot. Otherwise stick with the 570's. They'll OC better-ish.

Turns out many reviewers are blowing they're cards when they try to tweak voltages, and some with just regular OC'ing. Seems the problem is either with the Nvidia Power Limit or possibly some of the 12v resistors on the card.

Anyways, seems like nvidia's being price competitive on their best card!!!! Not shocking but I'm loving the effort.

Be careful when overclocking your 570 as well. I think the VRM's on any of the 5xx series aren't really up for high overclocking. Quite a few bit the dust in forum wars. I wouldn't push them much over 1.1v.

I'm liking the results of this card though. I'm glad some of the rumors putting it at equivalents to dual 460s weren't true.

Is pricey for a card though, but still a cheaper option for 4x sli then running 4 cards unless you already have a mobo with 4 spaced out pcie slots.

Something is wrong with your power readings for the 590 under load! From what other sites have mentioned the 590 may activationg its power limiter in both Kombuster and Furmark, which will give false readings and make your temp/noise/power readings unrealistic.

Simply put the power/temp/fan noise readings should be done on the games as you benched them, its all to easy to program a driver to fool one application to make it look and sound good.

For that reason we use Unigine Heaven 2.1 to gauge the power consumption. So the readings are good.

Thanks
