Fastest mac mini configuration?

[drifter088]

I am thinking of getting the faster configuration.
What would be the fastest Mac mini for 3d rendering/model work?

2.7GHz Dual-Core Intel Core i7 with AMD Radeon HD 6630M

or

2.0GHz quad-core Intel Core i7 with Intel HD Graphics 3000

Wondering this myself. Leaning towards the quad 2.0.
