Hi guys
I have a problem. I'm going to change my old 3650 graphics card for something new. I'm works mainly on sketchup autocad and Corel. Quadro is too expensive so i need somethink normal ..

Current equipment:
Q9550 + P5Q-E
4gb ram
raid 0
Eizo 1931 [planning to buy an additional monitor 24 "]

My models can be quite large, 2 million and 1 million line of face
The question is. What will be more efficient:
1x GTX 470/GTX 560Ti
or
2x GTX 460/GTX 550Ti

general rule a more expensive graphics card or two at the same price
