I'm upgrading my motherboard to the ASUS A8432-MVP Deluxe so i'm stepping away from my AGP graphics card and going PCI-E. My cpu is a AMD 64 3000+ and I was actually eyeing on the HIS Radeon X1900XT. I read a couple reviews and what I found was that I needed a high cpu to get more juice out of the card. I don't know exactly if my CPU meets that qualifications .. and certainly I do not know what graphic cards are out there anymore .. to many models (x800, x1600, x1800, x1900) .. my old graphics card was a EVGA Geforce 6800 (AGP) .. certainly the X1900XT is a greater card then the 6800 .. what is out there for me? I'm down to purchase the HIS Radeon X1900XT without a doubt, just don't know if I'll get everything out of the card with my system.
