Pros easy to install and runs like a dream no issues at all
Cons no issues !!!!!
Pros I can't get past the massive "con"
Cons Video fails under 64bit windows 7. Just watch two YouTube videos in a row and the the system freezes for a moment and then the video resets and you get a message that windows has recovered from an error. Asus knows about it and doesn't care.
Pros All cores are seen every time booted. Solid as a rock in all phases that I have experienced. Not a single problem.
Cons I don't know about the newer 89 series, don't know what the improvements were about.
Summary It was less than a week when I noticed the 890 series boards were on sale. The 880 were not listed any longer so I must think there was something improved upon with the 890 boards. I have had not one problem with my board so I cannot expand upon the con's and pro's of either.
Pros 1) High Quality
2) Easily unlocks hidden cores
3) Easily overclocks your CPU
4) Awesome performance (helped my CPU achieve 4.5 on Windows 7 Experience Index)
5) Comes with plenty of cables (example 4 SATA cables)
Cons 1) Integrated graphics are a bit weak (4.5 and 5.5 on Windows 7 Experience Index) - not really a big deal to me, because I'm not a gamer, so this performance level is sufficient for my purposes.
SummaryTypographical Error: This board helped my CPU achieve a 7.5 on the Windows 7 Experience Index (not a 4.5).

Pros Easy installation and there seems to be a lot more options to configure than I ever will need. A doubble sett of USB3 adds to the usefullness.
Cons For my use the Cross-Fire functionality is overdo. I'd like more regular PCI-E instead.
Summary I installed it yesterday with an AMD Phenom X4 965 Black Edition CPU, 4 Gb Corsair 1333 RAM and only the onboard graphics card and it works like a charm! Layout and connections is standard but offers personalization of settings like no other mobo I've had.
