I always recommend picking up an AGP video card or the newer PCI express style video cards. I also recommend the dual monitor output from a video card. I find it impossible to record with just one monitor. It's just inefficient to me. Even if you don't need dual monitor outputs now, you will eventually if you stick with recording.

I'm not up on video cards. I bought a good one like 4 years ago and just kept using it. I haven't noticed any issues. So do some research and get the best video card with dual monitor outputs that you can afford.

Make sure your video card fits into your motherboard.
