This is a great HD3850. My graphics card went out in my secondary PC so I needed to get a card fast and on a budget. So found this ASUS HD3850. It is factory overclocked more than the regular HD3850 at 1100 MHz and has the giant heatsink which is very effective. At idle, temps run 38-42 ○C and up to 69 ○C while being over clorate is no HD5770 but the ASUS HD3850 plays all my games prefect with no problems: 2010 Aliens vs Predators, Batman Arkam Asylum, Crysis, and etc. all on high settings!cked during gaming! Most reviews knock the HD3850s and of course its Frames
