Why hello there!

My mining setup:

7870GHz Edition (OC'd Core 1100MHz)
Diablo Miner ~392 Mhash/s

Flags are -v 1 -w 256 ... which were recommended in the Diablo Miner thread's OP.
I feel like I should be getting more Mhash/s though 

IIRC, these are very similar numbers to what my old 6970 was getting.
