looks good. performance per dollar is quite bad with a GTX295 though.
2 GTX260 with 432 cores together cost 260Eur and a GTX295 with 480
cores costs 370Eur. the 295 only occupies 2 slots instead of 4 with
2 GTX260 though.

scales linearly.

a single table occupies around 6gb, you can expect to fill 12gb per month
with a GTX295. For the sorting you may need another 6 or 15gb of temp storage.
that depends whether we dump stxxl which is slow and hungry (in the way it
is used now) for our own sorter implementation.
