depends what Res you are playing at, if you playing at 1440p or above (or over 3 1080p monitors) the 4GB may help..

If only at single or double 1080p/1200 the 2GB will be perfect..

Super cheap price too..

cheers at the moment 2 monitors 1080p max but near future when cockpit arrives 3 so would 4gb be a better option although it has a smaller core clock and boost clock

I think a 4GB card may be better for you then.
