mouse, coz we are terming it as a gaming rig, i seriously recommend a MS wheel mouse optical priced at 800 bux, coz play with other mouse and belive me u'll have tons of lag at low sensitivty..
naa, there is a particular mdel called "MS wheel mouse optical" which has I.E 3 sensor, where as MS wheel mouse basic has the normal sensor, its the sensor that different
MS wheel mouse optical costs about 800 bux for white and 850 for black :S
and a equivalent of its performance from Logitech is the MX 310 which as u said is 2000 bux, so not a hard choice to make IMO
