Not sure whether to go ahead and get a few new parts (i7, new case, motherboard etc....starts to mount up though!). Or would you wait for X99 chipset and 800 series of GPUs? Just wanted some input/thoughts really.
 
Oh or to get a new mouse and keyboard been using an old sidewinder (performance has been pretty good for the price) and a R.A.T 3 for over a year now! 

Alright sweet, probably will do. Been looking at the Black Widow Ultimate and the Ultimate Stealth. Not sure which switches I'd prefer, the quieter orange ones or the clickly greens. 

The primary components of your system look good, I wouldn't upgrade.  I would look into peripheral upgrades though, such as mouse/keyboard but more importantly audio (unless you happen to have a really good audio setup).

I went ahead and treated myself to a Deathadder (got it reasonably priced from Amazon for £48) and a Blackwidow Ultimate...the 2013 version with the blue switches not the new one with razers own! :-D......I just use my Soundworks speakers.

Good enough mouse choice though not so much for the keyboard choice.  Still better than your Sidewinder though.

well the onboard audio is awesome these days unless your doing your own audio stuff, so good speakers maybe 

Not awesome but definitely improved if you have one of the high end Z87/Z97 motherboards.  There's still a big difference between Realtek ALC1150 and a good sound card.  

only if your willing to spend the money, I bought a Xonar for my computer and sold it again, because my x540 5.1 sounded the same on it, or the onboard audio on my previous p35 board I sold 2 weeks ago

Maximus VI Formula oboard cant touch my SoundBlaster Z, i tested it for a few weeks. The Z is much louder, clearer and can deliver more bass when needed.
