Well I'm updating my comp. Well I got a 420 watt PSU. Now my current system is 512 MB Ram, 1.2 Ghz AMD, Geforce 5200, and a ASUS Nvidida2 mobo. Now i'm wondering if my next set up which is a extreme geforce 6600GT, 1 GB corsair ram nforce4ATX mobo, will my CPU be able to handle it? In time I will upgrade to 600. But thats not excatly anytime soon.
