RE: Pedals and Yoke
As long as you're getting decent frame rates now, you will be able to enjoy having the yoke and pedals. In my opinion, the CH gear is the only way to go for the price. Anything beyond that and you're looking at $1000 for the pair. Be sure to get the USB versions and they will certainly be compatible with your next system.
