I Don't know what to do!

Okay, for about 7 months now my brother and i have been saving for a new computer(we don't have jobs) and i recently decided to get a PS3 instead, and out estimated time to get the new pc is in september and i have enough money to get the ps3 with 80gb, new edition. But my bro declines and says we should wait to get a new pc. I DON'T KNOW WHAT TO DO! Anyone help me decide.

agreed, get a pc if the one you have is ancient and slow

pc has a lot better games than ps3 and a better investment in the long run

ps3 is too expensive for a gaming system, and with a computer you can do lots more than game (internet,music,document processing,printing,scanning,etc.)

wellmy pc ins't slow, nor is it aincent, but not good for gaming, i have like 6 steam games and the only one i can't run it cs:s, but i can play gmod, other stuff. mayby ill get that onlive thing when it comes out, but ill most likely buy a ps3 before a new pc.
