I do not troll Nvidia cards and personally have no opinion on which is better I am just restating some facts.

static benchamarks maybe but please show me any benchmark you would like to run and ill do the same.

I had 2 580 lightnings and sold them for the current setup. I am pleased to say t hat the tri fire setup is quite a bit quicker in games.

3dmark 11 favours the nvidia based GPU's a fair bit as there are some bugs with the ATI cards. This is not reflective of real world performance though.

And believe me, I am no fan boy, all my GPUS were Nvidia up until the latest setup.

Well of course 3 will beat 2, but would you mind getting the links for me I dont really feel like surfing 6 pages of posts.

the 580 is undoubtedly a more powerful card than the 6970, however 1. crossfire scales slightly better than SLI & when you put a price comparison into play, ie 3x 6970 or 2x 580's I would think its fairly easy to see what will give you the best performance outcome.

Thank you finally some one understands the difference between 2 and 3

plus your cpu will bottleneck the cards as is

get 2 6970 lightning off tiger for now
Zzz. Kinda surprised you were too lazy to search for it.

And at your above post, of course he was talking three cards vs two. That's what the OP was asking about. And I assume you missed why the OP was asking about 3 vs 2 or you wouldn't have typed what you did: 3 6970's are roughly the same price as 2 580's. Price was the comparison.

OP snag the 6970's or like others have written a 6990 (if you can find one for a decent price, good luck with that), and a 6970. Unless you are looking at 3GB 580's the 6970's run all over the reference design. Even with an aftermarket cooling setup and beefed up VRM's like the Lightning models. That being said, I assume from the prices you linked you are looking at the 3GB 580's? If so they are a fantastic choice, albeit at a price premium. 3GB is more than enough for any game at the moment (so far as I know), and should serve you well for a long time. But unless your talking multiple screens then that extra VRAM is worthless and your much better off with the 6970's. At any resolution the 6970's will still beat the 580's unless you hit a VRAM wall. Not something to worry about unless your going with a multi-monitor setup. However, if your going this route, you'd better be playing in Eyefinity/Surround or your wasting money.
