cool "mew" cards that are just as likely to be overpriced and nowhere to buy them from LMAO.
granted I like the "look" of the Armor MKII and this Mech Z (which appears to be a little more fully closed in than the Armor/Armor MKII, kind of like the Gaming X branding) time will tell. but seriously, if they do not have the clock speeds to back them up, to increase the price of RX 570/580 $120 or more over the actual MSRP is yuck.
put another way, if a cpu cooler costs $120+ (ship and tax) it better be superior to the "reference boxed (clocked) cooler" and in many cases many of these "custom" cooled variants for Radeon or Geforce (yuck) really are not worth the extra $$$ compared to just going reference instead, certainly not $60-$120 or more "better"
IMO...I be damned if I pay extra just for some fancy RGB that I never see anyways ^.^
