well i would like to use my new poker but it doesnt have F keys so that aint gonna work. i usually play with an IBM Model M but recently have been playing with a QFR with blues.
for DOTA2 i have to have a keyboard with Insert, Delete, Home, End, Pg Up, Pg Dn because that is how i setup my inventory. just like it is on the screen. i also use the arrows and the 0 numbad key for abilities. so for dota 2 i like the IBM Model M since it is the only full mech board i own.
other games if i can i play with the xbox 360 controller. i really like it. i use a PC with a GTX 680, i7 3770k, 16GB DDR3, SSD up the ass etc.
