Well the topic is pretty self-eplanatory. I'm eagerly awaiting the Ivy Bridge launch for my next build. In the mean time, I've been treated to the Z77 chipset launch so I've gotten a good taste of whats going to be available at launch as far as motherobards are concerned. The two I've picked out are the Asus Maximus V Gene and the ASRock Extreme4-M.
The problem I'm having is that the ASRock only has 4+2+...2? power phases whereas the Asus board has 8+4+2 phases. I know that more power phases = better overclocking stability, less VRM wear, cooler VRM operation, "smoother power delivery", etc. etc. But what I don't know is how much this difference really means in real life. I'm not the gamer I used to be, and the Maximus V seems like much more than I really need. I am however partial to Asus and ASRock mobos because they are feature rich, have the best UEFI's, good fan controls, and I like their aesthetics (for what it's worth). I also want to move to mATX, which generally sacrifice a few phases compared to ATX boards.
I'm just trying to figure out whether or not the Maximus V is really worth the extra $70 for me. I will overclock my future i5-3570K keeping stock voltages, but I'm never going to be shooting for any records. I am planning on keeping this computer for 3 generations (2nd generation after Haswell). The Maximus V looks like a better board all around (as it should be) but I'm trying to be practial here and am thinking that the ASRock board might be closer matched to my needs. I can afford either board, but $70 is $70. I can always use that money to make a good dent into my HTPC upgrade later this year.
Maybe the P8Z77 M Pro is a good compromise between the two? It has a 6+2+2 phase design. Please help me decide, PLEASE
