like I found the gigabyte ga-990 ga-990fxa-ud3 one in a cheaper price but idk the asus says all this cool stuff there around the same price but the gigabyte is 20$ cheaper I'm getting the amd FX 8320 that's why, my gpu is a amd 7970 oc edition, I want better performance I heard the asus one had better bios changing menu but I want the best so what do you guys think? Also when they put R2.0 or R1.0 what does it mean? And what's the best to get in that meaning?
