Ya, to be honest you can build a much better budget com for around $300. My friend is an idot and he bought a 9250 pci (I used a 9200 AGP for my old family comp) and Mine beat the crap out of his. I told him to not buy pci cards cause they suck, and then when he builds a comp fro his brother what does he do? Buys a pci GeForce 6200... I've yet to playtest mine vs his, but let's just say he plugged in an old Geforce Ti 4200 to see what the card was and how it played, and his fps in Source jumped quite a bit. (also, he was rendering it on a HD TV...)
I'd say ask your parents to chip in a little more and buy a s754 Sempron processor (I suggest the 2800 or higher), the stick it on a G6100 motherboard (nForce 4 mobo, has pcie x16 and onboard Geforce 6100 (not as good as a descrete 6200, but it plays CSS in 12x7 on high (no HDR, AA, or high refelections of course) and gets 30+ fps pretty well. Plus, you can later buy a pcie gfx card, like a low end DX10 later. Then get a cheap SATA hard drive, a case (the X-Qpack is pretty good for it) and a DVD burner. Pop in 512-1gb mb ram and it's a sweet budget machine. Honestly, do yourself and your bro a favor and just spend $200 more for something that works.
