<----Note the DATE of this review! Then read on........

Pros: Still running after nine years. Seriously, this is NOT a joke! Had this rig put together in 2007 by professional builders (Mysterybyte) in Halifax, NS, Canada. Had one HD replaced and replaced original GPU with Zotac GTS 460 about 5 years ago--that's it! Have run this rig at 2.4 GHz nearly every day (wrote two books on it), very seldom OCed for games-playing. No problem except lately: GPU driver occasionally blank the two 1440x1080 monitor screens.

There's not enough "eggs" to give to this review!

Cons: You kidding! Beat this record!

Overall Review: Now gathering bits to build an i7-6700K system (sorry, no Wins 10 for me!) in a Thermaltake Core P3 open frame chassis: Nvidia 1080 GPU, Plextor M8Pe SSD, Cryorig r1 CPU heat sink fan, ...more.

Works great with a few hang-ups

Pros: Compatible with almost anything.
Decent size.

Cons: Had a uCode error with Core2Duo processor. Updating the BIOS fixed this problem.

Overall Review: The size is prefect; all the inputs are in good spots. After the BIOS update, have not had a problem since.

better hope it work

Pros: when it works it does well - be prepared to upgrade the bios to accept even Core 2 Duo

Cons: This is my third P5B motherboard and it still doesn't work. I've RMAed with ASUS and get old repaired (?) boards back. The second one worked for a month. Since I'm paying the shipping and the phone bills (no 800 #), I'm going to try another brand.

Overall Review: Anyone can have a bad board once in a while. It's how they solve the problem that makes the company. ASUS fails miserably.

I wish I'd not held the first board so long before building the computer. Newegg has to be better to deal with.

AWESOME!!!!

Pros: Overclocking !!!! this thing is awesome. I overclocked my E6550 C2D from 2.3ghz to 2.8ghz without effort at stock voltages. FSB from 1333mhz to 1600mhz without issue too. For the price.... well worth it. Also supports 1333 FSB processors. 3DMark06 CPU score over 2500, which is the same score my son got on his Quad Core. hehe

Cons: None

Overall Review: Need to update to one of the newest BIOS's for this kind of result. I have BIOS version 2001 on it now. Using Patriot RAM PC6400 (PEP22G6400EL), and Sapphire Radeon X1950GT

It can suck

Pros: Kinda cheap.

Cons: The original BIOS doesn't support many CPUs and you may have to borrow an older CPU from someone JUST to reflash the BIOS.
Even the latest BIOS doesn't support some of the basic overclocking functions for my Core 2 Duo e7200 cpu (like changing the Vcore).
S3 suspend still leaves all the case fans turned on.

Overall Review: Overall, this is a bad board. One of the main points of buying an ASUS is its _supposed_ ability to overclock. I think many people have issues with this board and missing overclock options, even with the newest (2001) BIOS. The fact that the fans spin when doing an S3 suspend is really annoying too. You need to REALLY research to see if there are issues between your CPU and this board before you buy.

Very picky memory

Pros: 4 internal sata, comes with sata cables, the on board thing which name is lost to me....basically this little pass through for the hdd light, power switch and front led buttons, you can put them from the case onto this big jumper, which comes configured for the mobo, the bios is nice and looks easy to overclock when I do get to that....

Cons: lets begin, very very picky as to what will and will not work on it. check the asus website if you do decide to get this board, to make sure their small selection of memory is available. the board is also very flimsy, when installing components, it seems like it wants to break.

Overall Review: onboard audio is so-so. the memory and flimsiness is kind of a real pain. ok board if it suits you, just beware...

Perfect

Pros: Perfect, absolutely no problems. Switched up from a 478 socket machine to this, using a Q6600 processor. Worked fluidly.

Cons: None I have noticed

Overall Review: Possibly the best bang for your buck. Since the latest BIOS revision comes on this board, there are no installation problems.

Picky with memory, otherwise fine

Pros: Has a lot of options, came with 4 sata cables, and also included was a kind of pass through for your case cables, power button hdd light and such, made it easy to plug right in and avoided some mind numbing few minutes of most other motherboards

Cons: Very very very picky with memory. Check on the manufacturers website for exactly what you can use and in what quantities. Also, drivers are not in a format, nor could be extracted to run with nlite for a custom os disc.

Overall Review: If you are ok with its flaws, its an otherwise good motherboard. I just don't happen to be ok with its flaws
