It's a FACT that they're continually releasing new code. You and others continually ignore this and continue to spread the fud. What happened to waiting until the NDA expires for reputable reviews, hmm?
Various people with press kits around the web have stated that for the CHV, there are 3 beta BIOS - all of which were released very recently ... the latest one, late on Friday. It was also stated that the latest one improved performance significantly across the board. The leaked reviews on CHVs do not use this BIOS. The leaked reviews on other boards most probably do not use latest either. More revisions are expected.
I doubt if it's intentional as some people are saying (though early engineering samples may have been intentionally crippled), rather that management said it was launching and their coders are scrambling to finish optimising everything. Bad publicity, sure ... but everything points to this NOT being final performance.
