Mechanical Keyboard and new Mouse

[Cropels]

Well, yesterday I was playing BF4 and maybe of you noted that I was getting stuck in too many places.
My keyboard is a "Magic Eagle" and my Mouse is a "Spectra" http://imgur.com/a/fpUgC

Well, my keyboard can't detect more than 4 keys and when I press 5 keys, It locks himself by 3 or 5 minutes, beside this, the mouse is a great choise for gaming... except when the scroll don't work

I'm thinking to buy another Mouse and keyboard,
Keyboard : http://support.logitech.com/product/g15-keyboard
Mouse: http://gaming.logitech.com/en-us/pro...e-gaming-mouse

I never tried something of Logitech. Do you guys have another suggestion???

PD: I use the Keyboard for gaming and Adobe's Stuff (Photoshop, Premier, After Effects)
