Re: Upgrading graphics card
The PSU is garbage. If you put it in your computer, expect it to explode and take out everything. Brands I recommend are corsair, cooler master, antec, OCZ, PC power & cooling, and seasonic. I'd get one around 600 watts unless you plan on adding a second card later.
Also, what is your resolution? Unless it's very large, you should consider getting the 1GB 6950 to save money.
