GTX 570 to Quadro (Need advice)- Hello. I'm building a workstation to use the Avid Media Composer software. For now I followed almost exactly what the Videoguys DIY8 guide says (http://www.videoguys.com/Blog/E/Videoguys+DIY8+Sneak+Peek+Work+in+Progess+Coming+this+Fall/0x094b1737e0a06c495e5178a167fbdbd7.aspx)although I may use the i7 960 because it's half the price of the i7 970. The thing is, the Quadro videocard are too expensive for me. Maybe I could afford the Quadro 2000 but I'm not sure if it's worth it (not the greatest of the Quadros). So I was wondering, what do you think of buying a GTX 570 (the one I can buy in my country is the EVGA SuperClocked) and using the Quadro drivers?. Will it perform better than a Quadro 2000 or maybe a Quadro 4000? I know this questions are difficult to answer, but I'm sure somebody has already tested this. Also, appart from the modded quadro drivers, did somebody try to mod the bios? Thank you very much in advance. I hope this is the right section to post this. I'm new around here.
