oh snap. i didn't know custom 280s were out.
i'll tell you this much. i've owned 8 asus products and the only one never had issues (my 2560x1440 monitor which i paid $600 for). i would go for anything but xfx or asus. MSI and gigabyte have always been good to me.
avoid xfx cards like the plague though. personally i own an XFX PSU, but it's actually a re-branded seasonic.
