upgrade from a hd5670 to this and it be a world of difference . I think my computer be run modern game pretty decently before , but the difference be night and day now . be able to max out setting on bf3 , Skyrim , Fallout : NV , etc. . the card be huge and kind of block my sata port , but that be more my fault for not measure first . I be able to get it hook up , but about 4 of my sata port be unusable . overall very happy with this card .
