If you are looking for an temporary upgrade for just a year until you can get a new card, then try to dig up and TNT2 Ultra. My friend had one on a 650 Athlon computer and got 80-85 FPS at 1024x768 with vsync off.
If you can spend a little more money, $150.00, then you might want to look into the Kyro II.

The MX is definitely a good card and Morgan is right about the performance. You will only see a hit in performance when playing the big games.
The only way to get a GeForce 2 DDR(not GTS)is to buy a used one. I don't know of anybody who has one for sell.
I could send you my CL 3DBlaster Banshee AGP 16MB SDRAM, LOL.
