alright well first day i get it it be very sluggish . I do not know what be wrong with it , because compare to my old nvidium 9800gt ddr3 it be much quicker then this thing . after tinker around with some setting on the driver software the laggy-ness be fix . all you have to do be increase the speed of the graphic card and you 'll be run fine . now as for performance I be not sure yet but I will get back to this review when I test it out on some game .
