I have the DQ6 ordered as the P5B-VM was a complete fiasco.
If you took the time too do a google search on the "motherboard model +review" you would have read several reviews that says it overclocks very nice with the later BIOS updates.
Also, if you read the Gigabyte page on the motherboard, you would have read that it's 16x and 4x, not 16x and 16x.
