For after effects workflow
I work on a dual quad core machine with Nucleo and 12 gigs of ram so there is enough raw power to handle things. However I find that sometimes it's not the raw machine power but the way that you deal with the OS and the hardware that slows it down.
I must have things running very quickly as the design process is usually a slow process I don't need anything else to be slow.
I could not imagine how many mice I have gone through in getting the right speed and accuracy settings. From tweaking registry settings to buying expensive gamming mice. The problem is I am usually working on big screens and the simple test is I want to flick the mouse from the top right to the bottom left start button without having to lift the mouse and do a two stroke dance with it. It pains me when I see designers working like this.
I have found that the Razor line of gamming mice are brilliant. I have personally worked with the Diamondback and the Copperhead. Both of these sample at resolutions that gamers need but are perfect for speed/accuracy.
I've also investigated every mouse pad and surface imaginable and the one that works for me is the steel series. It was fairly expensive but if you want the precision you've got to pay for it..
Logitech g15 gamming Keyboard
I like the functionality of this keyboard. It has loads of programmable keys an LCD display for showing CPU power, time/date, media display, count down/stop watch. I always have it on cpu/memory power as this is the most relevant for me.
The programmable keys are very hand when doing repetitive work and are very simple to set up.
