hey everyone, i am new here, and i am also new to building a pc... so here is my situation:
I need a new desktop, and its main use will be for gaming and music/internet. The games i like to play arent crazy graphicwise, but they have a lot going on...main games i have in mind are Command & Conquer 4, Supreme Commander 2, and Starcraft 2 (as you can see i like real-time strategies).. anyway, my buddy who knows computers pretty well said i could build my own PC for significantly cheaper than a prebuilt from a retail store... My budget is about $500. I really don't want to exceed that much at all. so i did a bunch of research and came up with the following mock-up, please give me feedback, let me know if it will all work together, and any suggestions you might have, i have 2 graphics cards in mind because i don't know which would be better...
My main advice would be to spend less on the CPU, and more on the mobo. Right now, you haven't even selected an AM3 motherboard to utilize the bucks you are spending on your CPU. If gaming is your primary concern, an AMD Athlon II will take you far enough. Overclocked, they run games just fine. Since most games are yet to be extremely heavily multithreaded, the quadcore phenoms will give you minimal gaines.
It's my opinion that you should cut back a little on the hard disk too 1TB isn't really necessary, and use the extra over $50 bucks you save to invest in an AM3 board and DDR3 RAM. If you are willing to pitch in an extra $50-80 for a better graphics card, that's what will really bump up your gaming performance.
Some of my opinions, but I can't claim to be an expert..
CPU AMD Athlon II X3 435 $75
CPU Cooler Cooler Master Hyper TX3 $20
Motherboard Asus M4A77TD $85
RAM Crucial 2GB (2 x 1GB) DDR3-1333 (PC3 10600) Model CTKIT12864BA1339 $58
Graphics PowerColor AX5770 1GBD5-H Radeon HD 5770 1GB $150
Hard Drive Samsung Spinpoint F3 HD502HJ 500GB 7,200 RPM SATA 3.0 Gb/s $55
Case Cooler Master Elite 330 RC-330-KKN1-GP Black $40
Power Cooler Master eXtreme Power Plus RS-500-PCAR-A3 500W $40
Optical Samsung Black 22X DVD Burner SATA Model SH-S223C $22
dial back on the psu 550 is fine
also the hard rive 500GB is good enough
spend that money you saved on an actual gaming card
5570 is not a gaming card in any way
if you do not overclock that motherboard is fine
if the main focus of the machine is gaming you need at least a 5750 or 250 GTS
