i am currently benchmarking my graphics card and the result tombraider and crysis 3 gave me were astonishing
metro last light ran on max settings with normal tesselation and AA and i achieved a 45-55fps throughout the game (even on the surface)
i am checking fps via evga precision and also gpu usage
it seems on tombraider and crysis 3 the gpu is not showing its true potential

cpu usage is 60 to 75% max
i ran metro and bioshock infinite comfortably
tombraider and crysis 3 are actually giving me a hard time

actually i have very low temps in tombraider (due to 55% load i think) 55*c-60*c max (gpu temp)
my gpu temperature is usually 70*c during games (+- 2*c)
my cpu however has a temp of 73*c during tombraider
should i be worried, by the way there is a lot of dust in my hsf that i am constantly ignoring
also should i get a new coolermaster hsf (i currently have intel stock cooler)
