I have 2 r9 270 crossfired and i am getting lower framerates then my friend's 750 ti.

I have 16 gbs of ram - 2400mhz
he also has 16gbs, but only 1600mhz

Processor: fx 8350
Friends Processor: g3258

My motherboard is a 990fx killer($103).
his is a Gigabyte GA-H110M ($45)

Why is this? i paid $340(for the gpus) vs. his $135(for his gpu).

In league of legends for example i am not able to go above 300 fps, but his easily goes over.
I am only getting 130FPS avg.

And yes i do have the crossfire bridge connected and already enabled it in my settings.

in just about every game he is able to out preform my computer, I don't understand.
From forums online I see that one r9 270 is superior to the 750 ti, am i doing something wrong?
My cousin has an 280x and from forums online i see that crossfired r9 270s are supposed to out preform the 280x, but i am unable to out preform it.

It might be AMDs drivers and dx11 restricting your fps. I don't know league of legends but if there is a console you fps might be capped somewhere. When DX12 comes out you'll be more happy with your framerate.

Yes we have the same settings and resolutions.
My fps in league is 130 avg and 190 max, his is 350 max and 260 avg.
Both of my gpu's is at 100% usage I'm sure.

Hopefully :/ I am just upset to see that my 2 graphics cards aren't used to it's fullest potential.
and in game i set the cap to unlimited.

After disabling crossfire and running on one card, I am able to hit up to 250 FPS(beginning of the game) and averaged around 135 so its about the same as if it were crossfired...
