Help! First time trying to build an AMD system. I bought a Soyo KT-600 Dragon Plus and an Nvidia 5900 Ultra. I also have a gig of Kingston ValueRam on Windows XP. I have a Soundblaster Live Value card that I transfered from my old system. Just got done downloading all the driver updates and the system locks everytime I launch a game. It runs apps just fine. I can play music all day, so I don't think it's the sound card. Will the KT-600 board run the higher end video cards or do I need to pick up something with more horsepower. My processor is a 3200+, if that makes a difference. If a dxdiag or something would help, let me know and I'll post one.
