Hi guys, I need help choosing graphic card. I have a slim case Dell computer (C521) with Nvidia integrated graphic card - 6150LE. It does not perform well in Vista. So i'm planning to upgrade it. But i do not know whether or not the Geforce 512MB 8500GT (low profile) can run well on my pc since my pc came with stock - a limit power supply (280 watts), and I heard that the Dell's PSU is underrated. Is it true? If so what is exactly the wattage is if it is not underrated? Can my pc run the card?

Kevin,

What is your cpu? at an average, with the 8500GT, core2, 2 hdd, 2 banks of ram with a quality PSU - load should be less than 300w. If its underratted, I'd say that PSU might just go around 180-220w.

my processor only single core, AMD Athlon 3500+, 2.5GB RAM (2x512MB + 2x1GB RAM), DVD-RW drive, 160GB hard disk (with 2 partitions)... thats all... Oh ya, i have a PCIe x16 slot as well... but i dun have AGP slot. And my card only support low profile. Is it ok to run? Someone told me can run 8600GT but i'm not very sure.
