K, this is leaving a few components out but is a fairly nice budget mid-range gaming rig.
CPU = Core i5 2500, 209.99 USD (Note: this is not the unlocked "k" series chip, so I have selected a board that reflects that. For a little more (40-50 dollars), you can get a "k" series chip and board by downgrading the 460 GTX for a 450).
GPU = Asus Geforce GTX 460 768mb, 159.99 USD (You might be better off going with a Radeon card, but I don't know much about these and what would be considered the equivalent for the 460's price point. I say this mainly because the motherboard I selected only allows for Crossfire and not SLI).
Motherboard = BIOSTAR TH67+ LGA 1155 Intel H67, 104.99 USD
PSU = OCZ Fatal1ty OCZ550FTY 550W, 69.99 USD (It's cheap, but at least it's modular)
Memory = G.SKILL 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600, 47.99 USD (This is 1.5v memory recommended for P67 / H67 motherboards)
Total price = 592.95
Edit: Er damn, okay, I forgot about the case -_-; Well, you can probably deduct from something to accommodate that.Edited by jivenjune - 3/15/11 at 9:16pm
