Which is better, GA-965P-DS3 or P5B-E Plus?
This is for my new rig, please the advice. Thanks

The BIOS is one difference. Gigabyte uses an Award BIOS and ASUS uses American Megatrends. The Gigabyte rev. 3 board uses a hard fix to enable 1366 FSB while ASUS uses a BIOS revision to accompolish the same. The hard fix allows for slightly better RAM speed adjustment. Either board is a good choice.
