i have a crazy idea......save up all ur money......sell ur parts piece by piece, work for about 1 or 2 months, they buy a whole new system. hows that? cause the stuf fyou have now isnt that great either. Speaking of which, wat Processor do you have? and wats ur FSB Speed, thats probably whats holding you back. because if your computer has a 4x AGP slot and 250 Watt PSU. i doubt you have anything higher than 200MHz fsb and over 1.2GHz. Check ur system specs.
