I am currently in a little dilemma. I have a outdated 9800GTX+ which I am going to be upgrading, but I am not sure which card I should choose. I do some light gaming (mainly Call of Duty), but I mainly use my computer for graphic design. I don't use GPU heavy programs like 3DS Max. My programs of choice are Cinema4D and Adobe Photoshop CS5. From what I've read Both the Quadro and FirePro have drivers for these cards, but is it worth the extra money over gaming cards for light programs like Photoshop and Cinema4D?
Gaming card under debate: GTX650Ti
Workstation cards under debate: Quadro 2000 or FirePro v4900
Well it looks like you everything here the choice is just between workstation or gaming, but in my opinion I would get a 650ti because it is well worth the money considering how cheap it is, it has the capability of great gaming, and I have a friend who is a graphic arts major and uses the new 650ti in his build and is thoroughly impressed with its performance. The 650ti whould have no problem performing at its best in your rig.
