Yeah i've seen performance go down with 3 or 4 cards before, I think you need an insanely strong fast clocked CPU to get big numbers out of Valley. Perhaps it will favor Heaven a bit more?
hi thought I would add a sli 970 result but on 2560x1440p so the standard is 1920 but I run dell 1440p and not many results for this setup on here so thought add this on
cpu is @4,2ghz
gpus evga gtx 970 sc acx x2
memory=2400mhz dominator platinum
also if people interested also have 3 d mark score as well been asked about 970s a lot but see a lot 980s but not many of these I have no coil whine and I have the revised firmware from evga site and they work awesome
here is 3d mark result as well if its a problem message me and can remove 3d mark result
