Yeah Mike I'll swear by the ATI cards. They are great cards for anything 3D. Be it games or renderings from hi end 3D applications, ATI is my recommendation. If you set your virtual mem to those figures, you should see a good increase in performance... less lock-ups and crashes due to running out of mem. For even better performance, I'd recommend defragmenting your hd once a month even if windows says it doesn't need it. Your hd won't need to work as hard then. :)
