Building a new PC

So my girlfriend's sister is a gamer like myself and I built my computer for about 800 (not including screen) and her computer isn't exactly for gaming it barely runs as it so she asked me if she gave me the money if I could build her one so I said sure but I need some advice she said her budget is $600 (i know low but were both 16 and in high school) so if you could link me to a setup of parts from http://www.newegg.com I would really apericate it

 

For motherboard, look at the ASUS A8N-VM CSM.

It has everything you could ever need, including PCI-Xpress and onboard graphics in the form of nVidia GeForce 6150 chip.

It also uses the latest chipset, the nVidia nForce 430.

For processor, an AMD Athlon 64 3200+ or bigger.

Graphics card, an nVidia 6600GT, ATI X800 GTO, or an nVidia 6800 (or one of it's flavours)

If you can't afford a video card now, the motherboard's onboard can give you time to save and is good for backups and trouble-shooting.

Maxtors DiamondMax 10 with 16MB range of hard drives are fast and reliable.

Coupled with 1GB of RAM, it will give you an excellent system capable of playing any current game.
