I will chose my GFX card according to this.

Does it use ...

< 1,5 GB --> GTX 580 (1,5 GB)

There was only one guy I saw using a 3GB 580. And he is the only one capable of getting "40 FPS in the dreaded bombers-over-London mission" (settings on medium and high; 1920X1200 resolution). He says it runs silky smooth.

Here is the thread:

The game will use up all available VRAM:



So, for me the choice is obvious.

ok, 2 GPUS won't improve VRAM but doubling GPUS surely will

It won't. Not sure about CF and ATI cards, but with Nvidia and SLI even when you pair the two cards in SLI - you get the maximum amount of VRAM of a single card - it does not double up!

The common mistake nowadays is that dual GPU cards are the solution. They aren't. Dual GPU cards = CF or SLI "on a stick", with much worse cooling / loudness / chance to crap out on you.
