Summary: I just built a new desktop using this M5A87 MB with a Phenom II X6 1090T and it screams! I had no problems installing everything and the MB performs really well. I have taken the OC route all the way up to 4.0GHz and managed to stabilize it at that speed at around 51°C (and that's on air cooling).
Summary: What I like: Asus. I'm brand-loyal to them and this board affirms that decision. Bios. Easy to navigate and adjust, and fairly explanatory. Overclocking. Excellent control of everything. What I don't: Parallel and serial ports. Its not 1995 anymore.
Summary: I bought this motherboard to replace one I had bought last year, mainly for the USB3 and SATA3 connections. I had an accessory PCIe x4 card for my previous motherboard so I could use my SATA3 drive and external USB3 drive. I also have a SSD SATA2 drive used for my main C: drive.
