I have a Asus KNF 5-SLI MB Dual Socket 1207 pin with a quad core Opteron cpu @ 2.1Mhz in each socket for a total of 8 cores. I've just purchased a ATI 6950 2G card and have read that underpowered cpu's will cause the Video card to bottleneck. The threads that claimed this issue I believe were single quad socket . In any event do you think I will suffer performance with these spec's?? I'm working around to trading these 2 cpu's out and replace with 2 of AMD's 6 core cpu's for a total of 12 cores . I have to let the new wear off of them for a bit to save some $$ so I'm stuck with this current configuration. Will I suffer performance that is quite noticeable or not?? Thanks for any insight to this discussion
