It's a nice feature in the games that supports it. I personally don't care much for it, since I have a hard time telling the graphical difference.
Physx is a software engine that takes use of Nvidia's CUDA cores and using those to render. AMD/ATI uses the CPU to render Physx.
Only a very few amount of games supports Physx.
And indeed, a 500W PSU will be plenty even for a GTX 580.
If you strictly only game, as mentioned, the 2600K will proove no benefit over the 2500K at all. the 2600K primary has HyperThreading, which benefits in apps that can use up to 8 threads. Games cannot.
You can also get, as mentioned, 2x GTX 560's (no TI) or 2x HD 6870's. Or even 2x GTX 460 - they will all give you better bang for the buck while outperformind your current GTX 570.
If you choose multiple GPU's, remember to add a PSU with 4x PCI-e connectors. Like the XFX 650W. Very solid PSU and will serve as more than plenty. Even if you wish to add another GTX 570 later (if you buy it in the first place, of course).
Any questions ?
Btw, consider the ASRock Z68 Extreme4
motherboard which is $20 cheaper.Edited by p4p3r - 7/22/11 at 5:05am
