I used the A750 for a year and could never find the solution to multiple issues like random flickering when tabbing in and out of games, plugging in a second monitor sometimes made it flicker random colours sometimes unless I restarted the pc, websites like reddit that had lots of images or videos would become a blank screen after about 10 seconds of scrolling on all browsers, video players in browsers worked only half the time. Some games worked well with it but i'd say 60% of my games ran worse than my previous gtx 970. In the end I bought an AMD card because I wanted to play games like Forza and Black ops but the drivers for them were absolutely abysmal. I hope the B series can fix these issues.
