New HD5570...stuttering on startup??

I upgraded graphics cards from a GeForce 7800GT 256mb to a Radeon HD5570 1gb. After I installed the catalyst drivers and restarted, the computer stuttered to draw any new frame and was unusable. Any ideas?

My other specs:
Asus A8S-X mobo
AMD Athlon FX-60 cpu
2 GB PC3200 RAM
500 PSU
