When I asked you didn't say you had AGP!
You
REALLY don't want that card. Trust me. If it's so cheap-arse it doesn't have a FAN, you're going to suffer in any game you try to run off of it. It's so stripped down and underpowered that it doesn't produce enough heat to require a fan unit, just a passive heatsink.
That's a no-no for choosing a card!
Further, while in PCI it's one of the highest available numbers of GeForce available, that doesn't negate the fact that the Ge5000 series is widely regarded as one of the worst decisions ever. Terrible cards.
[EDIT: ***I only looked for NVIDIA cards because that's what you've listed so far, made me think you were only looking for them!***]Okay, in your original post you said under $100. Lower if you can but under $100.
Well, for $96 you can get this AGP Ge7600GS (about 1 million times better than a FX5600)

http://www.newegg.com/Product/Product.aspx?Item=N82E16814136008Or if you really don't have that money to spend, here's a Ge6800XE (budget card I'm guessing, still better than a 5000-series card) for about $60
http://www.newegg.com/Product/Product.aspx?Item=N82E16814141060Here's the link to the search I pulled on newegg.com The Ge7300s are stripped down budget cards for the 7000 series, but they have 7000 series cores, which are better at everything (even stripped down) than the 5000 series cards. However, if a 7600GS is available for the same price as a 7300, ignore the 7300.
Basically, 5000 series is for when you have no other options. You have other options so don't consider it.
