ive upgraded to a 660 and am happy to say the i get about twice the performance over my old 650 in 3Dmark. i am very pleased with its performance. ive been running furmark just too see how my new graphics card holds up. i ran furmark for about 6 hours and the results were good my gpu never went over 62 c and my computer didnt crash. however i noticed when my framerates exceeded 60 fps my computer would emit the slightest buzzing noise, its not a problem as annoyances go, but im wondering if i should consider it a problem as far as issues with the card should i be concered? or does your graphics card do the same?
