I'm building a gaming pc. i'm new to this, so i would like to know if this is any good? PROCESSOR: AMD Athlon(R) II X4 640 Quad Core MEMORY: Corsair(R) XMS3 8GB DDR3 GRAPHICS CARD: ATI Radeon(R) HD 5770 (1GB) MOTHER BOARD: Asrock(R) N68C-S Motherboard HDD: 1000 GB POWER SUPPLY: Quiet 700W Power Supply Thanks
That Asrock N68C-S motherboard is a microATX board with just one PCIExpress 16x slot. What can you possibly cram onto that board that is going to need 700W?
Save yourself some money. A 400W PSU is already more than plenty for your config as stated.
As far as playing graphics intensive games go, the HD5770 is a decent lower midrange card. You might want to use the money saved from getting a more appropriate-sized PSU towards a better video card instead.
Consider a GTX 460 1GB, or HD 6850, for better gaming performance. Not much more than the HD 5770. And go with a Phenom II X4, instead of Athlon II.
