I have two 7970's in my current rig with a 2600k. Unfortunately I'm running on the z68 platform so only one slot runs at 16x and the other runs at 4x. This is pcie 2.0 btw. Would I see an increase in frames per second if I crossfired the second card, or would the 4x be too much of a bottleneck?

Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
7970 crossfire question
- Thread starter outers
- Start date
In my personal experience with Crossfire, PCI-E 2.0 at 4x makes for poor scaling. If you are simply interested in gaming performance (not mining), now would be a great time to sell both your 7970's and grab a 780, or 780Ti. Probably could get a 780Ti for what you could sell your 7970's for.
I'm a miner so I gotta stay amd. I'm just wondering if I'll stay above 60 fps in bf4 if I run both in crossfire. As it stands I get drops below 60 fps on certain maps and it is really terrible.
What mobo do you have? I'm running a p67 with ivy bridge and get pci-e 3.0 @ x8 with xfire or sli. You sure yours doesn't do at least 2.0 @x8?rhansen5_99

You should be able to run bf4 60fps at 1080p almost maxed out stuff with just one card so you should be fine. Hardocp has a nifty playable review for settings. What board are you running or is it off risers for mining?
