Well I tried several performance tweaks from this thread.

I noticed on the 700wx the registry value for CompactionCritPrio256 was 0xFFFFFFFF which is a -1 in integer form. I didn't know you could have a priority setting outside of the 0-255 range. Anyway I changed it to a value of 80 with bta2dpsnd drv at 60 and wavedev at 125 and at first it seemed to really make a difference when also overclocked at 520Mhz. But after tweaking it some more and coming back to those values again it was lagging as bad as ever. So I'm not sure now. Anyway, something else for you guys to fiddle with.
