The deathadder isn't an MMO mouse, it's ergonomic. I play SC2 competitions, and it's the best mouse i've used personally, I find the logitechs too long and hard to pull back with as a result of their design, but if you've tried both in person it's all a personal preference. The G403 is another solid option.
All the stuff I mentioned is high quality, and the Mugen 5 can cool on par with mid tiered AIOs for less than half the price.
If anything the Corsair AIO presents more of an issue for replacement through potential leaks which they've had in the past.
3600MHz will net you practically no gains over 3000MHz which is pretty much the most you want.
The real cost comes from the Trident Z RGB part of it.
3200Mhz is the absolute highest you should go for gaming, 3000MHz is the best value. I've also chosen LED sticks.
Keep in mind most are running 2xxxMHz sticks, in addition to the fact a higher RAM frequency won't really say anything.
Bog standard is 2133/2400, 3000 is well above that.
You're getting a much more powerful GPU that can run most games at 4k ultra 60fps no problem.
Given you're new to this wouldn't it be beneficial to take advice from others?
I mean I work with hardware most days at a store, so it definitely helps in parting out builds.
If you want water cooling i've put in Fractal's new Celsius S24 which is one of the best available on the market atm.
Still comes out cheaper.
