Well... Games like HL2 have physics bound to a CPU thread, so if you use a PPU with HL2, you might have no performance increase, because the source code is not writen to access or recognize the PPU. You know when you open up the console in CS S or HL2 and it shows you the amount of physical/logical processors, your processor(s) speed(S), process instructions, your video card and the amount of RAM you have? The source code isn't written to search for a PPU, so you may not have any performance increase at all. I could be wrong though....
