I have just placed an order for a high end gaming rig. As part of the spec I opted for 3 x GTX 285 cards in SLI. Just as I was about to confrim order the new ATI cards came out. The guys building my PC suggested that I go for 3 x ATI Radion 5870's instead as these are DX11 cards. I will be using this PC for gaming and 3d art rendering. My question is which is the better option. the ATI has the DX11 support, but the Nvidia cards have the Physx etc. I have spent a lot of time web looking for an answer to no real conclussion. Any constructive advice would be gratefully recieved.
