First things first, I would like to thank all the members for their relentless patience while i tied to learn my way through building a gaming desktop.
I have bought the parts and completed my first ever build yesterday and it is great. Something really great about putting all the parts together and then powering on and the system actually works hhehehe.

CPU I7 3770k
GPU, Dual Sapphire HD7970 Vapor-x 6gb edition in corssfire.
Motherboard ASRock Fatal1ty Z77 Professional Motherboard

windows 8 professional.
I have 3 1080p displays in eyefinity, however i do game on 1 at times.
My concern is as follows, While I run 3d mark I get a score of 9300 for a single GPU and then 14970 for crossfire. However when I go to play games there is virtually no FPS improvements, I tried, Crysis 1, Crysis 3 and batman AC and I can not get any improvements.
Crysis 3 for example on a single 1080 pm monitor with all maxed out settings gets me around 70 fps, however i do not get better with crossfire either, so when i go to multi monitor gaming its drops to under 30 FPS which is odd given that these GPUs aren't exactly cheap.
I am wondering if the CPU is the bottleneck, however thought the 3770 k was quiet advanced for purely gaming purposes.
Can you folks please advise your thoughts on what could be the issue.
ALso I have no idea how to overclock a CPU, if that might help.

I am using fraps for FPS, some games a very stuttery such as Skyrim with just over 60 FPS maxed out. Battlefield 3 plays flawlessly with constantly being over 150fps and well into 200 fps very often.
Crysis 3 hovers between 35 and 65, which is disappointing given these cards cost quiet a bit, I could have gotten and gtx 690 for better performance.
Ah well, I guess i have to live and learn.
My question though, does the cpu have anything to do with this? could there be a bottleneck?
Since I've written you my last message, my computer started rolling Crysis 3 (1920x1080) at only an average of 14-15 FPS. I also tried playing World of Tanks with maximum settings (1920x1200) ( www.worldoftanks.eu ) and it runs at only 18 FPS (sometimes 8-9 fps) and my VGA card heats to about 67 degrees centigrade. Could anyone help me solve this problem? Where could this issue be coming from?
Thanks a lot in advance.
*Update* I tried testing in 3dmark 11 and I get the same scores. Could the above issue be because I only have 33 GB of 111 free space on my SSD drive C?
I think that it is ok that you get 70 fps in crysis 3.
I have a Sapphire Radeon HD7970 3GB Vapor-x graphics card. I tried benchmarking with fraps in crysis 3 and I get 28-29 FPS.
P.S. Is the corsair power supply enough for running crossfire? I have a Corsair hx1050 (gold certificated (90% efficiency)) power supply.
Yes the power supply is enough to handle crossfire. I have since traded the 2 HD7970'a for 2 gtx 680's which work a lot better despite lower vram.
