Searched the site along with google and am struggling to see if I will see many benefits from taking out my ATI 2600 and purchasing a second user GT 120? I just fancied an upgrade to take my mind away from those sweet 27" imac screens and also am hoping that an improved 24" ACD is released or even a 27". Obviously the new displays need the mini displayport socket so was wondering if I would see any benefits from ditching my 2600 and getting a cheap GT 120? I mainly use Imovie, Iphoto, web browsing etc and know that the gt 120 supports opencl so I guess thats a minor improvement. Hopefully the GT 120 is a slightly better card?
