How well can this new iMac run Dolphin?

[AVCP333]

Trust me, I know what you're saying. I'm getting the base RAM and storage options from Apple and then upgrading those myself, so the final price comes in just under $2,500. Also, about half of the final price will be paid for, so my out of pocket cost is about $1,250. Which is fine by me. When you say "OS X problems", are those driver related problems? If so, then I'll definitely install it on the Windows side. Will there be a difference between running Dolphin on Windows 7 or 8?
