IM a bit confused so maybe some one can help me decipher this, I am attempting to upgrade my cpu, to this Phenom IIx6 1100T , motherboard is gigabyte. GA-MA790X-UD4P now mine has revision RB-C2 also BIOS REV F9 socket AMD 3 step 2 .... according to gig website this processor should work, but 790XT , not 790X , on processor site says similar, I found almost no info on my revision RB-C2 , also if the F9 bios does it have to be exact ? or any bios UP to F9 will work?
