I have a Gigabyte GTX-460 1GB that I just purchased for a new build upon this forums recommendation. I don't plan on doing any gaming but instead some light CAD/CFD. Should I return the GTX-460 for something like a FirePro V4800? Will there be that much of a difference? Both cards support DirectX 11 and OpenGL. Will the 50-60 bucks I'll save be worth the hassle of RMA? Can both cards be installed on the same mobo? Thanks for the help.
Workstation cards do have differences from gaming cards. Since you're not doing any gaming, it's adviseable to get a proper workstation card such as the FirePro V4800. I have limited knowledge on workstation cards but I gather that they have a very different set of drivers that is optimized for professional applications like CAD so you will see a benefit in those apps. It should be an easy swap to replace it.
Yes... you should exchange it. Workstation cards are built for stability... and as noted, they have a very different set of drivers specialized for workstation programs (as appposed to GTX drivers optimized for gaming)
