hi guys which is better and im an nvidia fan not ATI at 2 gts 250 or 1 gtx 275???
GTS 250 SLI is faster than a GTX 285, so if you have a SLI motherboard, they would be the better choice.
Now, for a bit more money you could get the Radeon 5850 which would give you a bit better performance and DX11, though there are not any games out currently that makes good use of this.
So, I guess it comes down to DX11 and PhysX, which do you value higher.
