So I might be getting a new rig. My current rig is a AMD Athlon II x2 250 @ 3 Ghz with integrated graphics. I can run SSBB at 50-60 fps at 1x IR. I might be considering a i3 2100 build. Or a AMD A8 3850. The i3 will have either GTX 560 ti or Radeon HD 6870 for the graphics card and the AMD build will run on Llano's integrated graphics. Will the i3 be enough for 1080p?
Oh, and can anyone reccomend a good $500-$750 build for dolphin and gaming in general? I want to be able to play at 1080p.
