I suspect that which is better is software dependent.
I was actually thinking about this performance issue as it relates to XCode development. Actually development in general. You would think the quad core machine would be a better platform. I'm hoping to see some tests / benchmarks relatively soon.
The new Mac Mini's are very cool. It's a shame they couldn't get the AMD card and the Quad-Core into the high end model...too much heat I guess.
Either way it's a great update. I'll likely get the Server with 256SSD/750HDD model because the purpose if for media, FCP-X and such. I think the Quad Core chip, even though it has the HD3000 will serve me better than the Dual-Core i7 + AMD card.
