Nvidia Quadro FX 4800 good or no good.
I have a pretty beefy system right now and I'm considering upgrading my graphics card. I have an AMD Radeon HD 7570 and a friend is looking to sell me two Nvidia Quadro FX 4800s. I'm torn between the Quadros, an AMD Radeon HD 7950, and a Nvidia GTX 770. Any suggestions between them?
