My Gtx 680 SC was likely new on amazon and i bought and i was excited. My friend told me about MSI afterbunner that helps cool ur gpu but i accedently put core clock all the way to maximum and my monitor froze and so i had to turn it off i was worried that i broke my gpu but everything seems fine. Its been 2 month since i have this gpu. It was working fine and no problems but one day new update came out and i download it and now i get stuttering on bf3, black ops 2 zombie, and minecraft on max setting..
