Currently I have an nVidia 220 GT that came with the computer when I bought it a couple years ago. I have a 350w power supply. The motherboard model is MS-7613 (Ionia -GL8E) and the generic model for the computer from HP is "HPE-150t."
What I'm wondering is if a Radeon 5670 or 6670 would work well enough in my computer, or if I should get a new power supply and then a more powerful graphics card to go with it (and if so which one)?
Edit: Would like to add that I want to keep everything under $150
