Nice upgrade!!

Thanks!  What is the blue ribbon may I ask?

 
Very nice Mods Rig. Good job.     

Hey nice clean build man, very nice upgrade too from Dual GK204-400-A1's to Dual GM204-400-A1's 
 
But I gotta love this pic man, It just does it all!

Very cool how you have captured the colored lighting, what camera did you use?
 
As your MODS RIGS Page goes, the pics are not showing up, to fix this make them no larger than 1000 x 1000 pixels and nor larger than 2MB.
This should fix your MR page for not showing the pics

That is a very nice Camera you have there  
The one I use is an old Sony CyberShot DSC-V3 from 2003
Btw get an avatar man, would look neat, here one I made of your GTX 980's:

Interesting benchmark results. I was thinking about the same thing and upgrading to the 980 boards. The reviews I had seen showed a single 980 benching very close to my 680 SLI but I don't see enough performance increase to justify the expense of twin boards. I need to see what the 980Ti looks like.

Depends on what performance boost you are looking for.  For me, my in-game fps @1600p has almost certainly increased by at least 50% - especially after the increase in vram from 2 to 4gb.  I will expect this to increase as newer drivers are released.  I wouldn't use 3dmark as a real-world example though.  But yes, the speculated 980ti will certainly increase performance, question will be how much more and if it will be worth the cost. imo 4k gaming is not fit for purpose at the moment, the performance is just not there.

Totally agree. @ 1080p 144Hz.  680 SLI's are more than enough.  I'm completely happy at 1600p, but 2gb vram was beginning to stretch it.  I don't think ill be upgrading anything for a couple of years, and by the time 4k will even be feasible financially & performance wise, it'll most likely be time to build a new PC.  4-5 yr+ cycle for me!    

To be honest, bf4 was definitely a vram vram hog with ultra textures.  It's just the way of things as game tech progresses. 1gb was massive, then 2 etc. Generally grows & matches increasing resolutions.  However, SMAA should be the way forward. Brute forcing 4xmsaa is getting old, but the need for 4gb with increasing resolutions greater than 1080p is still there.  1080p in general, shouldn't need more than 2, but at this point it's more about how much gpu horsepower is needed to run the software. Unless lowering settings is fine or devs become more efficient.  Bf3 caused me to return my 570's with 1.5 gb vram and wait for the 680's in the first place,  the vram stutter was annoying.  

IMHO the 980s are a perfect upgrade coming from 680s. Good job.
