I currently have a Logitech G700 and to be honest, I love it.  It's always chewed through batteries pretty quickly, but lately it seems to be going through them much faster.  So much so that I started dating the batteries to see how long they last.  
 
Case and point, I put in a new battery on 10/24, just had to replace the battery today.   From Monday to today, I've probably used the mouse for around 24-26 hours give or take.   
 
So it's off to look and compare.  Corded mice are not out of the picture, but they could prove problematic when (if) I finish the new build, mainly because it will be several feet away off to my left, and I am pretty sure a corded mouse would not do so well plugged into a USB hub.
 
 

If you buy a quality USB hub preferably USB 3.0 it will do fine. I bought a cheapo USB 2.0 5 plug hub at el Walmarto and it had sever input lag. I'm sure you can find one at a reasonable price OR just a simple USB entension cable would work as well.

I've had the razer naga for several years now and it's still going strong. I've been thinking about the Corsair Scimitar
 or this Venus mouse, seems pretty good for under $40.
 
Does your keyboard have USB? I run mine through the keyboard and it works fine.

I have a Corsair mouse and I was so happy with it I bought another exact model and it is still in the shrink wrap plastic.

I was thinking to myself as I read your post "of course it does!".   And then I learned that I am incorrect.  So despite the expense of this keyboard, it does not have a USB pass through...  
 
For the record I have a Corsair K95.  And the pictures out there showing a USB plug lie. Or they show and older/newer model.
 
 

That's strange. My K70 has USB I would assume the K95 does as well.

I've returned Razer products in the past because their required software was so bad. I'd never recommend that brand of computer hardware.
 
 

 
Razer never even made it far into serious consideration.  I've read and heard about way too many issues with Razer products.   Another consideration is the background software.  Don't want half a dozen configuration programs going on at the same time.   And I'll admit that I am used to and like the Logitech set up process.

I've been using the Razers for several years. I'm on my second Razer now (first one broke when I dropped it on the tile floor) and haven't had any issues.

My 2 year old Logitech G500s is still working fine, i can't notice any wear marks on the side of the mouse or on the mouse 1-2 buttons. 
 
 

Im finding it hard to give up on and/or replace my G700. The G700 does come with a cord, but it's so stiff that I hate using it, so I picked up several more rechargeable batteries.
I'm waiting to see if anything remarkable happens around Black Friday.
