I was hoping that bulldozer would let me upgrade the 2 1090t's but from the review at overclockers, I might actually be better off with a P2 980 in some cases. BD is all over the map in terms of performance. It's clearly optimized for multi-thread integer performance which means i probably won't get much of an edge in boinc - since it's all floating point.
Oh well. Guess I'll have to wait for SB-E and hope Intel charges a reasonable price.

edit: oh, the 20k is just due to network issues and backlogs of wu's - which is starting to become annoying.
