Let's put aside the SSD topic.

It's really hard to get the 580 or even 480/470 card in any of the european stores. Could you recommend any other GPU with quite good ROI? I have about 800$ to spent on GPU's alone and want to get from them as much power as possible with best Watt ratio. Any ideas? Don't want to wait couple weeks/months for 580/480/470 to appear again in stores.
