I have a Sony Vaio PCV-RS520, 1 gig of RAM, P4 (3.00 Ghz), and a Radeon 9200 series. I'm one of those guys who does well to upgrade his RAM and put a wireless card in his computer, so bare with me. Here's the deal, I am quite happy with my set up right now. For instance, I had fun playing games like half life 2 and doom 3 and have never had trouble running software like adobe illustrator and the rest of the creative suite. I imagine that half life 2 and doom 3 can look better and maybe even have better framerates, but I hate bad framerates, so I feel like I would have noticed if they were hurting. Actually now that I think of it, I did have to turn down some things in doom 3 to get it running smoothly. One thing I am disappointed with is how slow my video editing software, sony VEGAS, runs. Because I want to start getting more into this I am wondering if upgrading my video card will improve my computer's ability to run this program and others like it. Is there a card that will help me out with programs like this and with the next generation of video games? What are the things that I need to take into consideration besides budget when I look into different cards? Which cards do you recommend? I'm not too concerned with budget, but the $300 cards seems too steep out of principle. Can any card go in my computer? How do I find out what can go inside?
