okay, so i want to get more fps in games such as FF:XIV RR, and LoL than i already have. right now, my pc has a i5-2500k cpu and a ati radeon hd 6850. which of the two would be a better choice to upgrade for more fps? i think the gpu would be, but i would like some more feedback. thanks! oh, and i run most games at 1920x1080
