NFS Underground was great, but was a little unrealistic. I really thought NFS Porche Unleashed had the best drivability, but now is a little old and won't be taking advantage of the nice 3D graphics cards that we've been upgrading too. I run a Xtasy 9600 256 MB DDR AGP in an old 1.3 Ghz with 512 MB SDRAM. Still works ok, but will probably be a little choppy with GTR. [After trying there was no chop evident even with running full graphics at 1280 X 1024 32bit ] I'll give a try though. I hope the Full version will have Multiplayer capability and maybe internet play.
