Re: 2 x 260GTX 216 vs 295GTX
Here, in the EU, the cheapest GTX260 core 216 costs 209E, and a 4850X2 costs 289E.
Check the performance in the games that you are going to play, and decide.
Also, think about things like CUDA, PhysX, DX 10.1, drivers, H264 HW Playback, ... or think about the possibility to add a 2nd 4850X2 in the future.
I think that the performance gap between 2xGTX260 core 216 & the GTX295 is very small to justify the price difference, but, you might prefer the single slot solutions for future upgrades.
