No, if only used for physx, it wouldn't bottleneck it. I've tested a 9600gso in a pcie 1x slot using it for just physx and it didn't seem to bottleneck it.
awesome that was the answer i was looking for thanks but, a 9600gso is considerably weeker than a 8800gts and so, it is harder to bottleneck, but the interface slot used is bigger with my 8800gts (PCIE x4)...
so whats the conclusion after knowing that...
bottlenecks or no?
