Friends I spotted something strange in VGA game test. please follow these two links. http://www.overclockersclub.com/reviews/powercolor_r9_290x_oc/8.htm http://www.overclockersclub.com/reviews/sapphire_radeon_hd_7790_2gb_oc/6.htm As you see settings are same but why in first link HD 7870 gives 35.1 FPS and instead HD 7790 saphire 2GB gives 36 FPS? 7790 can never beat the 7870 .
