There are many sites that are rich in information about the available online poker tournaments online. There are many tournaments like sportsbook poker, pacific poker, winner poker, titan poker and many more. I tried almost most of the games in http://www.casinostoplayat.com/. It was a good enough site and good response from the site.

I assume you are talking about what individual tournaments are the best of the best so I will give my opinion.

PokerStars, Sunday Million – $215 (16:30 ET) 1st = somewhere between $200,000 – $260,000

PokerStars, Sunday Warmup – $215 (13:00 ET) 1st = somewhere between $100,000 – $150,000

PokerStars, Sunday 1/4 million – $11 (15:30 ET) 1st = somewhere around $25,000

Full Tilt Poker, The Sunday Brawl – $256 (14:00 ET) $350,000 guaranteed prizepool and you get $40 for every player you knock out.

Full Tilt Poker, The Sunday Mulligan -$216 (19:05 ET) $200,000 guarenteed prizepool

Full Tilt Poker, The Double Deuce – $22 (16:22 ET) $200,000 guarenteed prizepool

It depends what you’re looking for. You might want to try a few poker freerolls first and then get into other tournaments and rake races. Try http://www.TrueMoneyGames.com for example, you’ll find a rather low participation which is pretty good for faster tournaments and less opponents, especially when it comes to guaranteed prizes.
