I presently have Nvidia Geforce 9400GT 512MB GPU, all is working great. I have on order from newegg a new Gigabyte Radeon HD 7750 1GB card, but after reading previous threads here on tom's hardware about AMDs Catalyst Control Center driver problems, I am thinking of sending that Radeon card back when I get it and not install CCC on my Windows 7 64-bit computer. I'd rather keep my good working Nvidia than have problems with AMDs CCC. Is that a good move on my part?
