I think a lot of them will work, which is why it isn't discussed much. If you aren't gaming, you will want a low power consumption card. I use an Sapphire ATI 4650 DDR3 in Win7-64 and it works fine. My main uses are general office and light CAD. The card can even do a little gaming if you'd like. And best of all, only $50 (or less). That's my experience at any rate, I'm sure others will have other options to consider as well.
