1.5ghz C2D, 4gig Ram, Laptop - 5box, Vent, mIRC, FireFox, MSN -runnin 30fps on main. I personally recomend Keyclone. Its got great features and for a 1 time fee of $20 you get GREAT support and you don't risk having to use out-side macros and timed delays which are against the TOS and EULA. If your looking for a free software solution check out Octopus.
