GTX 580 vs AMD 6990s Tags: Graphics Cards Gtx AMD Graphics Last response: March 17, 2011 8:54 AM in Graphics & Displays Share tkinz March 16, 2011 3:41:19 AM I am trying to select an ultimate graphics solution for a three monitor system, all of which are around 25 inches (if that helps at all) I want to know weather i should use 3 way SLI with GTX 580s, or if i should use 2 way Crossfire with AMD 6990s More about : gtx 580 amd 6990s Maziar a c 169 U Graphics card March 16, 2011 6:16:57 AM Neither 3-way SLI or quad crossfire scale as good as 2-way SLI/CF. So your best option is to get either 1 or 2 GTX 580's or 1 HD 6990. 2 GTX 580s>1 HD 6990> 1 GTX 580 m 0 l megamanx00 a c 107 U Graphics card March 16, 2011 4:29:24 PM ^ a single 580 can't drive 3 monitors Anyway, it just depends on the game you want to play. Some games don't support 3-way SLI well, and others may not support quad crossfire well. Just look at this triple GPU scaling article http://www.tomshardware.com/reviews/crossfire-sli-3-way... Considering the work AMD has done with eyefinity though I'd say go with the quad 6990s. Either way you go though, such a system is going to be pretty loud. You may want to go with water cooling m 0 l Related resources GTX 580 1.5GB vs AMD Radeon HD 7970 3GB - Forum I7 2700K and GTX 580 1.5gb vs I7 3770 and GTX 670 4gb - Forum GTX 580 vs. HD 7870 - Forum Help me chose!

Only one game where 3way crossfire didn't scale very well... all the other 3way sli sucked and 3way xfire did good. Instead of 2x 6990s go 3way 6970s, the 6970 gpu is a little faster than one of the gpus on the 6990 (same as the 5870 vs 1 of the gpus on the 5970). m 0 l lmulder March 17, 2011 3:54:41 AM Although to be honest I'm sure a regular SLI GTX 580 setup would be just fine. m 0 l Anonymous a b U Graphics card March 17, 2011 8:54:46 AM Don't you want eyefinity? m 0 l Can't find your answer ?
