Hello,
I have a friend that has a decent gaming rig, He mostly plays Minecraft with it but he wants to run shaders and something like LB Photo Realism at the same time. However his 4770K's Integrated GPU can barely handle Shaders at 1920x1080p. Unfortunately i do not know if a EVGA GT 640 4Gb would surpass it enough to make it worth it. I believe that it will with no problem, but i prefer to have a few more opinions on the topic.
