Got a 7870(Pitcairn) for my desktop (Win 8 - 64 bit) while waiting for my old card to go in for warranty replacement. Not overclocking for now, because my desktop isn't great on ventilation.

Running 13.4 Catalyst and APP SDK 2.8

On my dedicate mining machine (Win 7 -32 bit) and with my previous desktop card (6770), I used BFGMiner with no issues.

Now, BFGMiner (3.0.2 win64) crashes out instantly unless I am using poclbm, which even though the console hasrate is high, it is giving me garbage performance on every pool I try it on (Eligius, BTCGuild, Deepbit). I assume this is due to poclbm and stratum issues.

If I use CGMiner, with any kernel, including poclbm, there are no issues including with stratum, other than poclbm tends to overstate its hashrate in the console.

Any ideas on what I can do to get BFGMiner to run? I would rather use the same client for all my machines.
