People seem to want to get into arguments over video cards but here's what I think: Win2000 Pro or XP Pro- latest versions and upgrades. Makes a huge difference- plus a recent graphics card from the past year or two, with the LATEST drivers from the manufacturers- not Beta drivers- but one's they feel are very stable. I'm using ATI Radeon 128MB and and Matrox 64MB cards, and the drivers are probably one year old. Since I am not an active gamer, but like to play some (once in a while) with Flight Sim, Train Sim and my favorite- Crimson Skies (since I am SO DAMN GOOD at shooting down my opponents- big ego booster) I don't really have the VERY LATEST- which may also cause other problems. So anyway- POSER Pro-Pack, Bryce, Vue and Daz Studio all run great on my systems and basically am having no real problems with anything! Not familiar with XP Home, but the rest of your system sounds really good. DEFINATELY get an AGP card, unless you can support something even faster- whatever than might be!
