I have a HP pavilion p7-1298cb desktop with 12 GB of ram and a AMD A10-5700 quad core processor with integrated Radeon 7660D graphics. It only has a 300 watt power supply so I'm upgrading it to a 750 watt and now need a new graphics card to go with it. I'm trying to go budget so around $100 would be preferred but a little bit more money can be spent if necessary. I was thinking buying a Radeon 6670 I could use dual graphics with my integrated 7660D, because I can get a 6670 for relatively cheap.
