Right, glad someone warned me! Im gonna put my faith in the stock coolers!

The Palit and Gainward models.....are they just as good as the EVGA ones apart from the obvious warranty bonus you get with EVGA

If you dont OC much your PSU will handle the cards. I know my 750HX easily did 2 570's and they are within about 20 watts of a 580. If you are a big OC'er I would upgrade the PSU though.

To answer your question, there occasionally are apps (games/benches) that come out that don't have SLi support at release time.

In order for SLi to work nV has to make a 'profile' for the game and add it to the driver package ... or they sometimes make a 'sli enhancement patch' to get out the profiles for big-name stuff in between driver releases.

*Usually* the 'bigger' games will already have SLi support when they release, but unfortunately sometimes you have to wait for a little bit. Usually not past the next driver release though. And when new game demo's come out in advance of the game, it's actually somewhat common for it to not have SLi support added yet.

About the worst situation I've seen in the 2+ years I've been running multi-GPU was that it took over a month for SLI to work with 3dMark11 after it was released.

There are some workarounds to this though, ways to sorta 'create' a SLi profile yourself. I'm sure as the need arises you'll be asking us, and a lot of people here are familiar w/the various methods one can try.

The pailt and gainward ones have a non-ref PCB and cooler, which dumps heat into your case which you don't want. if you ever watercool them you will need to get the speciel waterblocks made just for them, the EVGA use the ref pcb and cooler so it dumps heat outside your case and you can use a normal 580 waterblock.

Well you could sli 580's for about $1K (if not more after taxes) or you could crossfire unlocked 6950's for close performance, but only cost you a little over $500, or you could still save money, 3 way crossfire them and destroy the dual 580's for roughly $250 LESS... Just my 2 cents...

Edit> Noticed your mobo has 2 PCIe slots, I'd still choose the 6950's. Roughly 85-95% of the power for less than 50% the cost. Unless you NEED 580's, by needing insane performance in 2 slots and wanting physX, theres no good reasoning behind its price/performance. At 2 slots a 6990 would be better than SLI 580's and in the same price range as dual 580's you can 3 way Crossfire a 6990 and 6970 (or 6950 unlocked). The AMD route is cheaper and faster this time around.

AMD is cheaper... I agree with... performance I don't until you get to triple monitor gaming... Hence is why he asked about 3GB versions...
Apart from pricing, two GTX 580 in SLI is the best dual setup you can get... period... I like knowing that my system has two of the fastest graphics cards available(and there is that premium), and sure they might not scale 99%, but they are close to AMD and will improve upon drivers...
Also going 3d, Nvidia is the way to go with much better support. Also this in SLI will allow 3d on all three monitors. The 6950/70's only have one dual link DVI connector on each card for 3d/120 HZ...
If you are on a budget, the 6950(biosed) can't be beat in terms of price/performance...
Also the 6970's are like leaf blowers and don't seem to be designed in being put sandwiched together.
