I am currently running an intel Q6600 with a single 8800GT. Most of the games I run right now seem to be CPU clock limited, since the Q6600's clock isn't that great (2.4 GHz). I've gotten some gains from OCing. None of the games use all 4 CPU cores.
I have a friend that has a spare 8800GT that I've thought about using for SLI. I've heard that SLI is easily bottlenecked by the CPU because of additional I/O, but I don't know if the additional CPU work can be offloaded to the idle CPU cores. Does it perhaps depend on the game?
So my question is: How do multi GPU solutions (SLI/Crossfire) scale with CPU cores? Is having a quad core the same as having a dual core?
