Go to solution Solved by Vek1313,

I have built a PC with two XFX 280x's in crossfire and I am still struggling to run lots of games. I have 8gb of RAM, 60gb SSD for OS + 1tb harddrive. I have an FM2+ AMD 7850k APU and an MSI A78-G41 Mate motherboard. 850w gold corsair psu.

 

I have no idea whats wrong as was wondering if you had any insight you could share. I thought it may have been that the crossfire was between one 280x and the apu's intergrated graphics but both cards show up as running i crossfire when i look at the catalyst control center. 

 

Thanks, any help will be much appreciated

It is your shitty CPU, right now I would pull out the 2nd one and keep it safe from dust and anything else and then crossfire the integrated graphics with one of the 280x if you really want crossfire. Then upgrade that cpu and mobo to intel so you have no worries of future bottlenecks, and when you do that you can add the second 280x in.

doesnt necessarily need a Intel CPU. could get away with a stronger AMD one so he doesn't have to drop a extra 60-100 on a mobo also. higher end amd chips will not bottlneck 280xs in MOST cases.

What I was saying is get a decent Intel chip for no worries of bottlenecks and there is the always ready upgrade path for when he needs to.

If he moves to Athlon (like 860K) then yeah he doesn't need to change motherboard, but if he moves to FX instead then he still need to change the motherboard.

I have yet to see someone buy a low end intel chip, then replace it with a higher end chip for that generation. by the time they want to upgrade, they will be the newest socket/cpu. not some (at that point) old platform. 

 

imho though. you may yourself, just seems a massive waste of money tbh

If he moves to Athlon (like 860K) then yeah he doesn't need to change motherboard, but if he moves to FX instead then he still need to change the motherboard.

this, a 860K would be great, if he was going FX at this point its better to just go intel. Really depends on how much he wants to spend.

Would an i5 4690k allow me to use the power from both GPUs? I know i would have to change out the motherboard.

Yes. An i5 will not bottleneck.
