Graphics card help

I'm cheap, so I've narrowed down two cards within a good price range of each other, both under 50 bucks. I'm not looking for blazing speed or the best graphics known to man. I don't need to run anything like Half-Life 2 or anything like that. Just an upgrade.
Anyways, I've narrowed it down to an ATI Radeon 7500, or a GeForce FX5200.
This is where I'm stuck. I'm hoping some people here with knowlege about these things could help me out a bit.
P.S. Right now I'm leaning heavily towards the GeForce, but I'm not certain. It does have 128 MB memory over ATI's 64 MB, and is slightly cheaper. But heck, I dunno
