There is a X360 Carbon board you know.... >_>
Newer games will demand better TVs. There is a VERY high chance that ProStreet for next-gen consoles will require 60Hz/HD-TVs. If you want to play ProStreet for your 50Hz TV, then buy the PS2/Xbox version. That demands less from your TV.
I know about the other 360 carbon board but i wanted your ansewr chingy as you know most about nfs games, and i know you spend alot of time here so... anyway i have my answer so thanks
