well, afaik you can grab an xt bios out of a Xt fairly easily, but no tools can edit them at the mo, only ati are giving out bios's with increased voltage and are seemingly only doing it for overclockers they give cards to and having them sign nda's to not release them. which is an utter slap in the face tbh, let overclocking twits doing suicide runs have free hardware and the bios's, but not let me, whose paid for the card, access to the bios's so i can increase my overclock for actual gaming. its the one thing ati have done to really **** me off.
now you can't edit the bios, but can you check what your current 3d voltage is Tim, has it changed up to 1.2v, a lot of people are showing lower core voltage on the pro's. so you'd think if someone could hit 850/950 ish with the lower voltage a XT voltage should go further on the core at least, with decent cooling. but its possible flashing an xt bios might just change the name and how its recognised, and not change anything else.
if they change the voltages then yeah, buy up those pro 1gb's, flash an xt bios and overclock the bejusus out of them with silly high bandwidth(are the pro 1gb's ddr4 actually, i haven't noticed).
. Great overclock btw 
(or is there?)
