Hi, I'm planning to build my own PC. First I want to know, what are the required parts I need to run and also make sure it doesn't fry the motherboard. Also, I want my PC to be able to play next-generation games (example : Crysis, Call Of Duty 4.etc), the DVD drive, sound card, Hard drive.etc is all stuff I can worry about myself. But someone please answer my questions : 1) What are the required parts to run a PC I'm building? Also without it burning the motherboard. 2) Whats the cheapest graphic card that has the ability to do this?
