okay. here is my computer specs, pentium 4 socket 478 (the old one) 2.4ghz (not dual core) 1.2 gb ram DDR1. But i have a pci-e slot. now, im planning to install games that require dual cores. Can i play them? I will just buy a high end pci-e graphics card. In my knowledge, I think processor clock speed will only affect the loading of the game. Right? PLease I need an exact answer. No guessing please.
