I currently have 2 XFX radion 5770s in crossfire. my main use for my computer is rendering and i am somewhat disappointed, would it be worth replacing them with one ASUS MATRIX GTX580. I guess what i am really asking is, is it worth the $600 i will have to drop. i am currently a student so every penny i pute into my computer i am taking food out of my stomach, would it be worth a hunger strike for a lil while
My guess is your rendering program benefits from CUDA and that's an nVidia only thing. 1st I'd suggesting talking w/ the rendering application provider's tech support and asking what success their program shows ....CUDA is only officially supported on the 570 and 580 in the 5xx series but you can unlock CUDA yaself on any other capable nVidia card using the technique here:
Remember that serious rendering is the realm of workstation cards (ie Quadro) and while the GeForce cards will work for someone who also wants to game a bit, at a certain price point ....$750 and up, the workstation cards will better suit ya rendering needs.
