4 out of 5 eggsFantastic, apart from one thing.

Pros: Fits in the NZXT M59 case like a glove, plenty of room for 2x460s, boots nice and quick and has excellent over-clocking potential.

Cons: The only reason I gave it 4/5 instead of 5/5 is because it lacks an SLI bridge, even though it's advertised that it's an SLI-ready board. It took me ages to find an SLI bridge by itself (eventually had to get one from a friend.) Sure, I could have ordered one - but the board should have come with one in the first place.

5 out of 5 eggsGreat features for the price

Pros: SATA 6Gb/s, USB 3, RAID, Whats not to like! It does what it is advertised to do. Marvell RAID chip boots faster than any other RAID capable motherboard I have worked with.

Cons: The slow boot is mostly due to the Marvell onboard RAID chip. That is to be expected with RAID.

Other Thoughts: I haven't owned this MOBO for a month yet, so my review is a little preemptive. the MSI product page says it supports SLI, I will have to wait and see. Also Ubuntu linux does not fully support the P55 chipset, ex. I cant get suspend to work. Not a motherboard con, just something to be aware of.

3 out of 5 eggsConcerned

Pros: The Board works, it has Sata 6 ports which I wanted for my Crucial Sata 6 SSD. It is the cheapest board with this option. Shutdown and application loading now much improved (likely due to the SSD drive and better processor)

Cons: I am running an i7 750, 2 gb DDR3, and the Crucial SSD drive. Bootup is significantly SLOWER than my old CoreDuo 1.8, 2 gb DDR2, and regular 7200 hard drive running Win7. It is like the Board stalls for 5 seconds on the MSI splash screen before even trying to boot Windows.

Other Thoughts: Anyone else had this problem??? Fixes in BIOS??

5 out of 5 eggsWorks Great

Pros: Works as planned.
i3/i5/i7 compatible.
Price.

Cons: None so far.

Other Thoughts: I used this Mobo to build my first PC. I wanted to do a relatively cheap build that I could upgrade later if I wanted to make a gaming PC or whatever. I'm running it with an i3/4gb ram/350w ps/cheapo ATI 4350 video card. What can I say? It worked like a charm first time I turned it on, and a few weeks later it hasnt blown up or anything. Now I have the option of putting in a nice processor or a couple of video cards if I want.

I was a little trepidatious buying this considering it had no reviews, but it works great!
