I'd say its really only down to your resolution of your monitor in your case boarder.
If your monitor can hit at least resolutions of 1900*1200 then yep, go get it. Otherwise imo you won't be getting price for performance. My res is 1680*1050 so unfortunately there isn't really much point in me getting one. Suppose I could future proof and get one then upgrade my monitor.....

get an GTX280 then you have the option of sticking a second one in sli... if you need, nott hat the X2 isnt a good card! its slighlt better than the 280 BUT its £100 more and only fractionally better.
