Building my own pc: amd or intel. PSU. Motherboard. GPU and display?

yes the OCZ StealthXStream II, 500W will work and it looks like you will have a awesome pc and for the money i would use amd phenom 2 black edition just read before messing with voltages you can kill the cpu but you can get major over clocking on it though and the mainboard i would chose is Biostar TA790GX A3+ Motherboard that is the best board for the money as well
