Intel X79 Mobos: 4 DIMMs or 8 DIMMs ?

[Epsilon-Zero]

By now many people have heard and seen a few of the Intel X79 boards supporting either 4 DIMMs or 8 DIMMs.

So far at the Gigabyte camp strangely both the basic and extreme motherboards shown support 4 DIMMs with the boards in the middle supporting 8 DIMMs.

4 DIMMs
GIGABYTE GA-X79-UD3
GIGABYTE GA-X79-UD7
GIGABYTE G1.ASSASSIN X79
MSI X79A-GD65
MSI X79A-GD45

8 DIMMs
GIGABYTE GA-X79-UD5
MSI X79A-GD65 (8D)

The logic behind why the more overclocker friendly boards have only 4 DIMMS has been explained that each DIMM will have access to the full amount of bandwidth available and thus avoid any kind of memory bottleneck, but how this will relate to real world performance has yet to be seen.

So I guess my question is what route would you choose?
4 DIMMs = Higher Memory Bandwidth
8 DIMMs = Up to 64GB of memory available.

4 DIMMs is plenty for me... at least until Haswell.
