Well, people say you can get about 30-40FPS on high with one. But I'd opt for a Haswell chip rather than an Ivy Bridge chip.
Why is that? I know very little about this type of stuff, still researching could you please elaborate?
So after much internal debate I think my best option is to go with a core-i7 cpu (w/HD 4000 internal gpu). From what I have seen this will give me what I want to play on med to high settings. But most important it gives me a good base point to go from in the future. I will probably end up adding an additional GPU in the future should I decide that I need one, but I beleive its the best bang for the buck.
So my new question becomes, how big of a PSU do I need. The websites I have been looking at say I need less then 100w PSU?!??! If this is the case then I can just go with a nice little <$40 psu and save even more money..
