CF unlocked 6950 bottleneck

post #1 of 4
Thread Starter 
If i added an extra unlocked 6950 to my rig would my cpu bottleneck it? Would the psu be enough?

I'd say your ram would bottleneck it before your CPU would.

Also, you may want to repost under PSU's so Phadreus can field your power supply question.

If it is a reputable brand (Corsair, Antec, Seasonic ect) then the psu should be enough, possibly close but should run it. Less reputable brand... fire is a possibility

I'm thinking on running 2 6950 CF and flash them to 6970 with my 750W PSU. If I need a bigger PSU, I think I'll keep it at 6950.

Calculating power usage on gpu is not my strong side
