Improvements? Unfortunately the only one I can suggest is getting better RAM. What you should have done is put a little more thought into a computer, or at least not bought such expensive parts just to have "moar powar". It would be a real waste to redo that computer after you already bought everything.
CAS latency, which is kinda more important than the clock speed (but 1200Mhz in a PC like that is laughable, 1333 is the bare minimum for high tier computers, 1600-2000 is the better range) is basically the time it takes between when the computer tells the RAM it needs something, and the point where it actually serves it up. The lower the better. Explaining the specifics of it can get tricky when dealing with what the cycles are vs how the speed effects it, but to keep it simple do this.
Take your CAS, and divide it by your speed.
10/1200 = 0.0083
Thats the time it takes for your PC to get stuff from the RAM. If you were to bump up the speed of the RAM to 1333 you would get a faster time because
10/1333 = 0.0075
Lower time equals faster speed. But dont be tricked by faster clock speeds being faster. A 2000Mhz kit with a higher CAS can be beaten by a 1600 kit with lower CAS latencies. Finding the balance between speed and CAS is where you will find your higher performing RAM kits. For you X79 board, Id go for one of these kits:
Mushkin 32GB 1600 8-8-8-24 timings
G.Skill Trident X 1600 7-8-8-24
Im sure there is other ones but I just did a quick search on newegg.
Stay away from dual Titans unless you just want to throw money away for a tiny bit of bragging rights. You can pick up two 7970 Ghz cards and save a good bit of money, or go tri or quad crossfire with the 7970's and beat out a SLI Titan. The titans are largely just fluff compared to the love they get. You can get more performance out of other cards if you do it right.
IPS monitors are not hard to find at all, and only slightly more expensive depending on your size and OMA. Sub-24" and you can find them for $200-300 easily. They only get really pricy when you hit bigger sizes like 27-32". The quality difference is insane though. Well worth the extra you will pay. Check out Dell's website for them as Dell's IPS monitors and monitors in general are nice, and they have constant deals on them. Just pick one you like, bookmark it, and wait for it to eventually go on sale.
For example, heres the one Im using and have loved it since I opened the box.
And if you can ever get those temps under control, I would recommend bumping up your CPU. Having all that money in something like that and at least not bumping it up just seems so casual. You dont need to, but you really could.
Its not really a bad build at all, but it just seems ill thought out. Like you just focused on spending money, and not putting it to its full use, which is what at a core, the enthusiast $4000+ computers are trying to do. No reason at all to spend so much if your not pushing that extra power around. Otherwise, a sub $1500 could do pretty much anything that one can at almost no visual difference. Unless you are running on more than 2 monitors though.
