From what I've seen around, the Hercules are the unquestioned STOCK performers. They also use TOP quality parts. I tend to see Hercs up top for stock and then BBA, then Gigabyte, then Creative. Those are the standouts.
I'd specifically stay AWAY from PowerColor, usually their memory is inferior, and their cores sometimes even have issues (like the bottom of the BIN chain).
Take a look at <A HREF="http://www.hardocp.com/article.html?art=NDgz" target="_new">this [H] article</A> and see their experiences with P.C. Check the overclocking section in particular.
Sapphire's not bad, but still they have had the occasional memory issue (but I haven't heard any for the R9800 series, just the R9700 series).
The 2.2ns memory is ONLY found on the 256mb version almost ALL the R9800Pro-128 run the Samsung 2.86ns memory. Also stay away from any that have the 2.8ns Hynix modules. They seem to be just crap at overclocking.
Anywhoo, that's my two frames worth.
