I have an Nvidea GeForce FX 5200 that seems to work great for me. You can probably up pick something similar at CompUSA, that's where I bought mine. I think it cost around $70. Also Like Sams says, you might want to get a bigger hard drive. I have a 160 GB internal and a 250 GB external drive. And also more memory, like 1 GB. You didn't say what kind of processor you have. That is also important. I have a 2.8 GHz Pentium 4. With that I get pretty good rendering speeds.
