I have a workstation computer paired with a Pentium D 805 and a nvidia quadro fx 4400, and while I'll use it for general use, would it be okay to play light games on it? (like shadowrun returns and bioshock) I understand the quadro line isn't meant for gaming I plan on replacing it with a amd gpu. I just wanted to know if it's okay for casual gaming with it's limited memory how do they handle 3d games? Also I cannot find the geforce equivalent for the fx 4400/3400 any ideas what it is?
