I upgrade from a gtx 260 . this video card work the first day i get it . I be run bf3 on ultra setting on 1080p without any lag . when I boot my system the next day , Windows 7 keep lock up due to a NVIDIA driver issue . I do not matter if I use the latest driver off of NVIDIA web site or the driver provide on the driver cd , Windows continue to lock up after approximately 30s . evga be a great company and honor its warranty . I hope to get this issue resolve ASAP . until then , I have revert back to my gtx 260 . my power supply -lrb- Antec Quattro 850 W -rrb- be not the issue since my gtx 260 consume 201w tdp and @ 36a on the 12v rail and the gtx 670 only use 170w tdp and 30a on the 12v rail . Update : EVGA 's customer service rock ! the send I a replacement card and it be run as expect . all dx10 and dx 11 game be run at a average 60 + fp with graphic setting set to the max at 1080p . the temperature of my card do not get above 62c under full load either and it idle at approximately 27c .
