I'm building a new system and looking for a new motherboard currently. I don't know very much when it comes to the motherboard portion of the PC building. Overall I will be playing games on this PC currently what I'm going to get is...
For gaming, you really don't need anything higher than a P9Z77 V or V-PRO
I'd go for the ASUS Maximus V Formula! Woo that board is HOT!
I recently built a new computer, almost same specifications but with 24GB RAM (Video editing hmm) and a Maximus V Extreme. Both the motherboard are almost the same, extreme is actually for extreme OC, formula is for gaming. And the sound! OH the sound on the formula is MIND-BLOWING. No kidding. I've tested it.
Yeah so, if you wanna game hard, there's nothing better than a Formula/Extreme.
Edit: Oh wait, just read that you got an i5. I got the i7 3770K. The i5 is actually better for gaming!
