what bios for gigabyte p55a-ud3 ver.1

hey guys,
in the middle of building this new computer, just waiting on my psu and cpu cooler to arrive
so i got the gigabyte ga-p55a-ud3 and a intel core i5 750 quad core, what bios should i flash the motherboard to?

I would download the newest available bios for that board. Gigabyte has some great software for directly downloading the newest bios and flashing it for you. Check your driver CD for other software and it should be there. Also welcome to the forum
