I'm deciding on whether i should get a gibabyte gaz77x-d3h or an asus P8Z77 V Pro. I'd like to oc my cpu to 4.8ish. the gigabyte mobo has a 4 pin cpu power connector, and lower power phases. Is the extra 70 bucks worth it for OCing at 4.8? Although not all cpu's are alike, what clock rate can i achieve with 1.3 v on ivy? Maybe 4.7? Thinking about getting an H100i.
