I am wanting to make the upgrade from 1080p gaming to realistically widescreen mode (single monitor) at 1440p. I have been buying the components I figured would be acceptable step by step as money has become available. I got a QNIX 27" as an interim Monitor (which I intend to become a 2nd screen) when I started to notice issues with the fps ..which might have been going on all this time but the low fps lock on the old 1080p monitor may have hidden.

I currently have:
QNIX panel I've OC'd to 100mhz at 2560 x1440 + old 1080p monitor
i7 4770k cpu (not currently overclocked)
1x R9 290X reference card (not ideal I know)
1x R9 290X ASUS custom cooler card
16GB DDR ram
Samsung Evo 500GB ssd
MSI Xfire ready mobo I believe (will update when I get home)
Corsair 1000w gold sli/xfire ready psu
Windows 8.1

I "feel" something is wrong with the FPS for this setup is low I rarely top 45fps averaging around 30-35fps at the native resolution of the monitor, which concerns me as I was honestly expecting much more, and would mean even staying at that resolution and going widescreen would decrease performance even more.

As examples currently playing:
Alien Isolation (downscaled to 1920x1080 to get smooth/playable fps)
Shadow of Mordor (~30fps)
Total War: Rome 2 (which averages 35fps on the benchmark iirc)

Is this normal performance (Everything admittedly on ultra for example) for a Xfire PC @ 2560x1440? or could there be something wrong somewhere? This is my first dual GPU system btw.

Things I've tried so far:
Different drivers (latest gfx drivers and the beta drivers)
Checking for software running in the background/malware scans/etc
Making sure Xfire is on (heh)
Only using a single monitor to see if the 2nd one significantly affects performance.
Fresh windows install.
I am of course running items fullscreen.

Feel free to ask any questions, give instructions or anymore information and I will try be as forthcoming as possible thanks.

Update, did further testing last night.

When taking out the ASUS card my fps average at max settings jumps to 56fps... If I use the asus card individually or include it in the xfire setup (As either the primary or secondary card it stays at the original ~30fps.
