What GFX card are you using? I have a 2010 MP with an ATI 5770 so if I do go this route I will need a NVIDIA card with CUDA. Any real world performance suggestions would be greatly appreciated. Software and video card as expensive as my bare tower is a little daunting without knowing the facts. Currently I am using color but have played with a REAL davinci with control surface and I am in love (I can't afford the davinci control surface). Thanks!
