system upgrade for the computer challenged

[SC/KG_Butcher]

thanks for the advice i forgot to mention that i will be upgrading to win 7 64 bit .This wont be the only game i will be playing so i want to get maximum benefit from this upgrade too as money is pretty tight at the moment.I also need to upgrade my track IR at some point because its a version 3 so that needs attention.Fortunately i have CH pro pedals, throttle, Fighterstick etc so they will keep the cost down again.I also am getting a new camcorder and will be wanting to do some editing there as well and some you tube posts so i have to factor those in to the equation
