7970 hands down
ive had
4870 xfire
5850 xfire
6950 2GB xfire
6970 xfire
and i sold out and am going 7970,
in the majority of games ive played dual gpus offer a higher average frame rate sure, but in MOST titles minimum FPS has been SLOWER then a single gpu,
now if a 7970 is avg 70 vs 6970s avg of 90 but the minimum fps is 45 on the 7970 vs 25 on the 6970s guess which setup feels better 9 times out of 10,
I dont care what bullshit numbers people want to pull its only PART OF THE EQUATION!
Im an FPS whore, the more the better especially in first person shooters like Bad Company 2 and Battlefield 3, where anyone whos gamed with me, from my 5850 to 6970 xfire setups the performance change from that and from switching from AMD to Intel cpu, showed an immediate improvement in my performance in game, in terms of score per minute K/D you name it, so ive always wanted more FPS till i hit my sweet spot.
Now while the above is true in shooters, ive noticed in games like Skryim, Fallout New Vegas, Last Remnant, Singularity, and others, that there would be rendering issues with multi gpu or other issues
for Skyrim and New Vegas it was 0 scaling
for last Remnant / Singularity / bulletstorm it was rendering issue,
etc etc, of anyone in this thread ive changed gpus probably more often and gone dual gpu out the gate on release day for each gen,
I say right now, 2x 6970s are WORSE then 1x 7970 in the majority of games due to how the game feels in terms of responsiveness,
and considering BF3 had an update that gave most 7900 series users a nice fat 15-20% performance bump, the crossfire 6970s dont even stand a chance anymore,
now if we look here and add 15% - 20% to the 7970s FPS here we see the 7970 boost to 71-74 fps essentially exact same performance as the 6990 and this is before adding one of those nice monstrous overclocks
now add in a 16% overclock w1zzard managed on his sample giving an average of 14% more performance add another 14% on top of that base 62 thats another 8 fps bring the 7970 up to 79-82 FPS lulz
