R9 290 Vapor X Crossfire Performance issues

[ace1ndahole]

Hi forum, recently I have "upgraded" my PC by adding a second R9 290 Vapor X for crossfire. The performance is horrible in Frostbite games, and when I play other GPU bound (not CPU bound) games like Hitman Abs and Tomb Raider, my computer would crashes, hang, or the game just become so chugged or stutter so bad that it's impossible to play.
I play at 1080p (looking for a 1440p monitor atm).

My budget Rig:
2600K @4.6ghz w/ H80i noctua nff12
ASROCK Z77 WS
R9 290 Vapor X Crossfire
Kingston HyperX Fury 1833 Ram 8GB dual channel
Seasonic XP3-1200W Platinum
2 MX100 256GB SSD in Raid0

My friend has almost the same build but gets way better performance than me in benchmarks like valley, and unigine. During gaming he always gets better FPS even though he game on 1440p while I game at 1080p...
4790K @4.6ghz
Gigabyte Z97 SOC
R9 290 Vapor X Crossfire
Gskill 1600 8GB RAM
Cooler Master V1000 watt
840 EVO 120gb

Any help or advice would very much be appreciated.

Why get a second 290 for 1080p? a single would be fine for even 3 1080p screens!
Battlefield and other frostbite engine powered games are usually better optimized for Nvidia. Except BF4. BF4 is the firsty BF series that is more leaned toward AMD.

As for the other games, try updating drivers. Know that NEWER drivers are never the best, you should find those drivers that suit you and best optimise for your specs.

I said earlier in my post that I'm looking for a 1440p, and it's my choice to upgrade, so why bother asking "why".

I have also tried 14.9 and 14.11beta with no success, the thing i'm asking is my friend almost have the same build except the better CPU, is it possible that my system is chugging because the 2600K is not powerful enough?

And frostbite games run just fine on AMD, friends get constantly well over 110fps on 1440p in BF3 and BF4 while I can't even manage 100 on 1080p, is our CPU that much of a difference?
Also the thing is I can run BF4, BF3, and Dragon Age Inquisition EASILY with a single card and get well over 90 fps on max setting, but when enabling Crossfire, the FPS just tanks and would crashes or freezes my computer like I said earlier. I thought my windows 8.1 installed was bugged and did a re-install and the problem still exists.

What temps are you hitting and what is your average fps would you say? Also 1 290 for 3 1080p? I can tell you from first hand experience while it will run it, if you want acceptable frame rates and high settings it wont run it well. I think 2 290's for 1440p may be slight overkill, but it's probably the same thing I'd do. Your cpu shouldn't be causing that much of a problem btw, youre 100% sure that crossfire is enabled in the control center?
