What is a good video card, that can handle video rendering in real time.?

I need a video card for a 150, maybe a little more.|||Assuming that $150 is your maximum price, I suggest the ATI Radeon 5750 for ~$145 on Newegg. I don't have much experience with NVIDIA cards (being an ATI fan) I think that the NVIDIA GeForce 220/240GT card would also suffice, for a cheaper price. But I'm not entirely sure on that one. I think the GeForce 9800GTX would also do fine on this for a bit more. I suggest checking Newegg for prices, they're the cheapest and they're the fastest.
