I have a friend that's upgrading his GTX460 to an MSI GTX670 Power Edition. He has an i7 950 on a P6x58d-e mobo, 6gb (3x2gb) and a Corsair TX750 PSU.
We were thinking about running the GTX460 as a Physx card but weren't sure if the PSU would be able to cope, or even if there would be a big enough performance gain to want to try it.
What do you guys think?
He thinks he will also be overclocking the CPU, he wants to aim at 3.8ghz using a CM 212+ and also has 10 fans with LEDs and cathodes in the case. Would that push it too far?
