Before this I had 3 GTX480's in SLI, changed due to overheating-, scaling and money problems. In a few days I'll be rolling with 2xGTX580 3GB @ 972MHz
yea if your sitting on 2x 580 3gbs theres no reason to upgrade. im on 2x 6950 2gbs great cards they run everything I want at the settings I want. but i have that itch i need to scratch so 7970 with its overclock potential will give me something to tinker with. add a second one later for some extra fun.
Thats what its all about but in the end its still a moot point the cards not shit as you put it.
still faster overclock vs overclock
972 is roughly 20% faster due to non linear scaling closer to 18-19% increase over stock
that puts the 580 3gb give or take at 1920x1080 and higher at 2-4% faster then a 7970
Sapphire HD 7970 atomic is still 41% oc = 38% increase so 7970 is still 35% faster give or take and at the ultra high end GPU segment AMD multi gpu scales a bit better then SLI does, so with 7970s in xfire on mainstream titles 2x 7970s at 1335 core as per Sapphires launch would be around 40% faster then 2x 580 3gb at the same price point.
so at this point same price larger performance benefit. and the game I play most just dosent like SLI which is kinda sad as previously it loved SLI aka Total War series
Shogun 2 responds better to Xfire then SLI where as every previous game liked SLI and hated Xfire. It all boils down to games. and right now 2x 6950s are 10% faster then 2x 580s in Shogun 2. 7970 in that title destorys everything else. cant wait to try that game out and test it again. to see what happens.
altho same can be said with other games. like Lost Planet 2. where you needed nvidia gpu to really enjoy that game. or better yet 2x nvidia gpus.
eitherway your point of the cards being crap is rather invalid.
It boils down to user experience and games played.
Ive honestly had 0 issues with drivers from AMD as of late, skyrim xfire was the only real problem and it was solved with radeon pro .
now my 4870x2 on the other hand i had some issues with at release. but I digress 7970 is faster and will remain so untill Kepler launched in which case ill sell the 7970 or 7970 xfire and buy 2x Kepler gpus. depending on price
