well after spending an entire afternoon i managed to get my 7950 gx2s running in quad sli.
the problem is im not getting any real performance increase.
as a reference i play cod4, with the single gx2 i manage 85fps (i use v sync) and sometimes drop to about 30fps depending on the map.
im still getting those fps with quad sli. if i turn off v-sync then i can average 150fps but i still get those horrible drops down to 30fps.
im just wondering could it be my cpu holding things up? ive checked everything else. temps are fine, both cards are working fine too. i have tried older drivers but that made things worse.
my specs are...

amd 64 X2 4200 2.21gig
2gig ocz ram
quad sli 7950 gx2
1000w psu
SB audigy se

I wouldn't complain about 85fps , some people can't even get it running.

the problem with SLI is that the more cards (cores) you add, the less each new card increases performance. In otherwards it doesn't scale well.
