Overclocking ASUS

Are ASUS boards easy to o/c? I was thinking of getting this one.

A7V266-E KT266A
SOCKETA
ATX
AGP
5PCI
ACR
DDR
ATA100
W/ RAID

And what do all those mean? I know what some of them are, but what are the ones like ACR and ATX?

Yes they are easy to overclock.
The atx refers to the style of the motherboard ie it fits in a atx case.

Not sure what acr is probably one of the riser slots no one uses.

Anyone else have some experience with ASUS?
