I saw someone selling these (ATI X1400, NVIDIA 7900GS, NVIDIA FK1600M PRECISION M90) and wondered if they can be used on my machine. I have a Gateway W350a, mobo is T-1628, 3GB RAM, Turion x2 64 TL-60, ATI 1270. I've looked at my mobo and the cooling components of these GPUs won't fit. Can I remove the cooling unit and install the board alone? I'll be using the machine for browsing, videos, and photo processing; gaming is negative due to the age and specs of the setup.
