Thanks for all the help guys. I too am considering building my first PC, and it's pretty daunting . . . but I agree that the Tested article is quite helpful, if a bit beyond my budget at this time. Thanks again. For now I'll have to stick with what I've got, but I'll get around to buying the parts eventually.
This may seem obvious, but I think your labors can be for naught unless you hook yourself up with a nice monitor. I just bought myself an ASUS VS247H-P and it is awesome--greatly improved my experience until I can build my own. I used this review guide for monitors to buy it.
Are you all pretty much partial to the i7 processor? I've seen almost universal acclaim, so I think I'll buy it.
