Hello, I just recently purchased a second 7870 and this one is a sapphire ghz and my first one was a gigabyte 7870ghz. I've been playing a lot of games with it maxed out and seems to get a constant 60fps. The cpu is running at stock 3.4ghz but I've noticed that crossfire doesn't get any good fps on Battlefield 4. So is my i5 bottlenecking these two cards? Also the graphics cards are running at matching speeds

lmfao... I found crossfire fun to experiment with, but in the long run when I built my first Quadfire system 4 x HD3870's it was probs the biggest waste of money I ever spent, although it didn't stop from crossfire'n 2 x 4870's later, it was grate when it worked or games it did work with but still money would of been better of spent on a good 1 x graphics card based system .. I don't bother with crossfire or sli any more. but if ya new to it, then it can be fun tech to have.

large spikes tend to point to what they call micro stutter have you tried running game with crossfire disabled see if its smoother

yes bf4 is a buggy mess, don't remind me that I wasted my money on it at launch as well as premium for it :(

turn vsync off, and you have the newest beta drivers for the cards? A few updates ago they fixed crossfire stuttering supposedly

it's probably just the buggy game itself then...I can play it 60fps no problem with my single 7950 on ultra, but it would randomly crash, or crash and tell me my gpu needed to be upgraded to one with at least 512mb memory....when the 7950 has 3gb, it's utterly ridiculous lol.

I've got 2x 7850s (OC) and they weren't bottlenecked by an 8350 (the i5 is marginally faster than the 8350) and I was never bottlenecked. I would say the i5 is fine and you probably have an issue with drivers or maybe vsync is enabled. First try Vsync. Then try the drivers (as Battlefield 4 is relatively new and older drivers may make it run slow).
