Aopen tend to sacrifice a little (and i mean LITTLE) speed for stability, which is not a bad thing in my books. They also tend to overclock well although in some cases only after a bios flash (my AX4G Pro wouldn't overclock by even 0.3fsb until i flashed the bios, now i can get my 2.53 to 2.91 effortlessly). I would say it's worth getting.
