one of the best motherboards for z77 and SLI. if you are looking at this now, probably one of the few options left. not a big fan of ASRock's driver website though. i just let windows 8.1 do its thing and didn't really bother with the extra stuff asrock offers on their website since this is going to a purpose/secondary rig that will only do csgo/fps. but i'll delve into the software optimization a bit later.
