Gigabyte EX58-UD5/Extreme Discussion Thread

[Nhawk]

I am considering buying a GA-EX58-UD4P MB.
I don't plan to liquid cool it (XigmaTek 1283 will do I think), but it will be in a fairly cool basement. I only plan to run a single video card (right now 4870).
I won't have more than 3-4 HD on it (now Velociraptor, Seagate 1.5TB, WD500GB).
Is there any point in going for UD5 or putting Extreme BIOS on the mobo?

I bought a 920 D0 chip and plan to get OCZ Platinum 1600. (I will likely OC the chip to ~4Ghz)
