Also I am looking for at least a 512mb video card.
Any help would be great thanks!!Your comp comes with a 300 watt PSU by default. If you have not upgraded it, then you probably won't be able to get a great graphics card. There are, however, some DECENT low power graphics cards that you could get.

These are all the fastest cards with no extra power req:

Nvidia GeForce GT 210 through 240
Nvidia GeForce 9400 GT through 9600 GSO
Radeon HD 5550 through 5670

You can find all these on newegg.comThank you for your help. I think I will stop by bestbuy and get EVGA - GeForce 210 512MB DDR2 PCI Express Graphics Card. $40 dollars doesn't seem to bad for it imo.
