It isn't supposed to change the CPU clocks.
 
Are you overclocking the CPU? XMP is also an overclock and sometimes the CPU can't do both a high memory frequency and high clockspeed OC at the same time.

Closest would be K70 RGB Rapidfire.  Has the MX Speed switches, USB pass-through, full RGB and macro control through CUE.  You lose the 6 dedicated G-keys and Hardware Playback that the K95 Platinum comes with.

K95 for sure.. trust me on this.. you will thank me later

Well, if money is not a problem, you can get any of these:

And buy a separate higher quality wrist rest. 

Not at all. I find that my fingers rest on the grip or the bottom of the buttons, which is at the same level as the grip

SteelSeries Rival 300 is also good
I have average hands and I fingertip grip it
 

I've been on an abyssus for the longest time.
 
It's a fine fingertip mouse, and it's worked, but its sensor isn't super amazing and it's a bit small for my taste.
 
I would recommend an EVGA TORQ X5 (not the laser, the optical one) as it's got a similar design (bit bigger but only just), fine switches and a pretty great sensor (the Pixart 3988).
 
Yes EVGA makes mice lol

nah, but i feel colors
