Well, that's a difficult one, in my opinion, as the A-series processors come with a GPU capable of actually doing things, especially compared to the Intel HD graphics GPUs, but the intel processor has more processing power.
Be wary, though, if you chose the intel one, because the GPUs in newer Pentiums are inadequate for most things, while the a8 has a GPU that's able to play video games at it's very most capable.
addition: er... actually, I just took the time to read what you said again. I don't see why you wouldn't buy a GPU with the a8, other than the fact that it comes with a whole 8570D WOAH (the d symbolizing what of itself it chokes upon when trying to do great things). I'd say get more powerful; if you're able to throw in a dedicated GPU with your $65 processor but not with your $65 processor, I think you should be rethinking your priorities. You should move up from pentium G to i3, at the least, if not i5, and still throw in some graphics, unless you're just using dolphin. For dolphin, the i3/i5/i7 GPUs are more than enough.
