I'm looking to upgrade my graphics card soon and was looking for advice. At first I was thinking I'd go for the Radeon HD 6770 but I'm not sure that my little PSU can handle it. I was looking at the 6670 as an alternative. Thoughts?
the 6770 shouldn't have a problem on a 350W as long as it can deliver the power. However, your psu isn't good and you should really consider replacing it. It only delivers 180W on the +12V rail which I don't recommend with the 6770. The 6670 should still work.
