Sorry, but the best driving game on the market today can only be found on the PS2 system, and that's GT3. Its worth the price of PS2 by itself. Graphics are insane, the handling has always been its trademark, and the quantity of cars to choose from, is second to none (all real cars I might add). Unfortunately its not available for PC because it could've looked real nice on a computer system.
The handling is great if you have never raced a car before. I found it to be extremely unrealistic. Some of the greatest dynamics come from NFS5, Driver, Carmageddon series especially TDR2000. Damage, oversteer and understeer are fantastic
