Won't a 6450 handle it just fine?
That is simply the name of Intel's 3D solution. AMD and Nvidia have their own little marketing names for the same thing.
Real answer is what series you need for each item:
-Nvidia: GT 430 or better
-AMD : 7750 or better
-Intel: Ivy GPU or better
small correction. for intel gpu. sandy GPU or better. must also be a core processor.
