What would be the best way to go with a $150-$200 budget with an Ati GPU? I have always used Nvidia GPU's. My client wants The full AMD Dragon platform. I was considering 2 4770's or 2 4830/4850's (if really make that much of a diff). For my budget would I be better off running X-fire or getting like a single 4870? He has an I-INC 25" LCD btw.
