Maybe look into a build like this one below, you did not tell us your monitors rez so i fit the best GPU i could in. The i7 860 IMO will be a better CPU for mya, PS work. It would help to know what is more inportant to you gaming or graphic work because you could go the i5 750 with a HD 5850 that will give you better FPS in games but a tad slow CPU for PS mya.
