I got a bit of fun out of Burnout Paradise, but you might find it boring. It certainly wasn't frustrating.
Actually, I have played Burnout Paradise for the PC. The career mode was kind of repetitive, but overall, the game was crazy fun, especially the online play.
If you like the Burnout series, then I recommend Flatout Ultimate Carnage. That is one crazy game right there. There are races and demolition derbies, shit is flying everywhere a lot of the time, and the drivers flying out of the windows... Good times, good times.
There's a game I have found last night. It's called Crashday. It was made in 2006 for the PC, it has racing, stunt competitions, demolition derbies, guns and missles, car customization, a track editor, good graphics, a kickass soundtrack etc. I cannot believe that this game is unheard of, seeing how well-made it is! It really surprised me when I first started to play it!
The car physics are more sim-like, but that just makes it more fun for me, IMO. I'm the most excited about the track editor, as it is a lot like the one in the DOS classic Stunts, where you place track pieces tile-by-tile, easy peasy. This game might become addictive.
Crashday is only for the PC, though. I dunno about your computer, but my computer is more than capable of running it fine. And it works just fine in Windows 7.
