PS3 or XBOX 360  

PS3 is powerful and good quality. But the game is small, and can only play legitimate games expensive. And some exclusive game is still quite good, such as Metal Gear Solid 4, there is a God of War 3 can expect. Can say that PS3 is a bit small, refined, specialized, expensive features.

360 Although I think the comrades of his merits, the picture is good, play pirated save money, there is one point among the 360 in the three major console online play is to do the best. At the same time, you play pirated might lead to your host was BAN (found in change machine, and then blacklist your network account), and then there is a need that is 360 times the courage to endure three red risks. The pure character of the fight.

Should I buy a PS3

Well I would think that both systems easily overheat only if your playing 6 hours with no stopping every other day.

I would say you should get the PS3. The new slimmer system is the same costs. Allows blueray and internet connection and can do everything the old PS3 can except for two things. Play ps2 games and install linux on it. Plus it has about 120 gb memory and you are able to remove the hard drive i think. You can always get a cooling fan about 40 dollars but with that you should be able to play those 5 hours non stop and be safer (not completely) that your system worn't overheat. I'm a ps3 fan so its just what I do.

Plus Final Fantasy XIII will look much much much better on the ps3 than on a 360. I can't wait for Versus XIII

Well i think X360 wind in every category like price, performance, game , online.On paper, the PS33 is more powerful but in reality, it's quite inferior to the 360, without getting into too many details, the three general-purpose CPU the xbox 360 has are currently far easier to take advantage of than the CPU on the PS3.

If you buy X360 Jasper , i can't eaily overheat like falcon and xenon. If you are a hardcore fps gamers i think you should buy X360.

I prefer the Xbox 360 for several reasons: it seems to have a larger library of games (at least in the North American market,) it the basic console package comes with more accessories, and the online play has priority updates. The overheating seems to no longer be an issue.
