Nice thing about AMD is the interchangability of coolers. Socket A, 754, FM1: they all use the same cooler fastening system.
I bet it is the same for 939, 940 and AM2/3/3+ as well (But alas not for F, C32 and G34, but they may be interchangable amongst themselves).
So if you are in possession of one or more real good cooler(s) for older AMD systems, then there is a very big chance that the cooler(s) may serve another round.

Speaking about RAM plans: My new FM1 Mobo can even be stacked up to 64 Gb of RAM, in 4x16 GB not-yet-deliverable sticks.
But there is a big chance that it will not be able to use 64 Gb of 1866 or 2133 RAM, at least not very soon.
The present manual mostly does not go further than 8 Gb setups and already warns that the black slots -you are supposed to place the first two sticks in the blue ones- may not be usable at very high memory speeds (2133 to 2400Mhz)

GEIL 1333 can be fast, if it is the 7-7-7-24 variant. Only G.Skill (7-7-7-21), OCZ and Corsair (7-7-7-20) offer better, according to the F1A75 manual.
Those 7-7-7-20 puppies are not garuanteed to work in all four slots though. 9-9-9-24 offers you more chances for a future 32 Gb.
In fact GEIL 1333 Mhz 9-9-9-24 is the only 16 Gb setup listed in my F1A75 manual (GET316GB1333C9QC 4x4)
