I object! Pro Street is the WORST NFS game ever created. Wait for NFS Undercover. You'll be glad you did. And don't get Battlefield 1942 either. Battlefield 2 is WAY better. Period.
The games I would recommend is...
Command & Conquer!
The best series in the world, you'll love the strategy and heart-stopping action with immensely good graphics for little requirements!
A few games from the series I would recommend is...
C&C Generals - Set in a modern setting this game will blow you away with great graphics and gameplay! Be WARNED! It will ONLY WORK ON XP UNLESS YOU CHANGE THE SCRIPTS in some way that I can't remember.

C&C3: Tiberium Wars - Its 2047 now, and things are WAY in the Sci-Fi age complete with a great storyline, and nonstop multiplayer, this is the ultimate Sci-Fi strategy game!
