I'm running an ASUS A88X-Pro mobo, with an A10-6800K APU oc'd to 4.4ghz, 4gb of Patriot Viper Xtreme memory oc'd to 2100mhz, and a 650 watt Ultra power supply. I would like to know what dedicated GPU to upgrade to. I've got a budget of right around U.S. $180. I'm not interested in any fanboy B.S., just want to know what card will be good for running most games at 1080p with medium to high settings. Games I play include World of Tanks, and World of Warships, Skyrim, also big fan of the Assassin's Creed series too...
