For those apps, (don't you dare judge) I'd use a mac. Apple has always been better, graphically anyways, than IBM. IBM's claim to fame is in sheer processing power, basically what's needed for games and office software, but for photoshop etc, the macs win every time.
Other than that, I'd go with an i7 or Xeon over an i5 or FX, you get all the multi-thread performance of the 8 core fx's plus the single-thread performance of the i5's all in 1 cpu. It costs more, but it'll do more in a broader range of applications depending on where their strengths and resources are.
Edit: ouch, just saw the dates. F. Me lol. Teach me to surf on a phone.
