Hey guys I have a P6T SE and have had it for a while and just bought an EVGA x58 SLI-3. I do not plan to run SLI, but I did want to buy a new video card and run my GTX 460 as a dedicated PhysX card. Is the x58 a decent upgrade or should I return it and buy something more useful? I already have 10 gigs of HyperX DDR3 1600, i7 975. Was OC to 4.0 but it became a bit unstable. And can I even use 460 as PhysX? Haven't ever done it. Thanks
