Personally, I would suggest you sell your PS3 and use the money to buy a Xbox 360. Most of the bad problems (such as the 'Red Ring of Death') have been fixed in the newer models (so buy new), and overall the game selection is good. :celebration: And no crappy PC viruses to worry about.
There's a slight problem with this idea.
The Xbox 360 version is said to have the problems this time around, and the PS3 is supposed to have even better frame rates and less bugs than the Xbox 360 version.
And I'm sorry to say, but the RRoD has not entirely been fixed. I'm pretty sure I saw some reports of hardware failures even on the new Xbox 360s. The problem has only been dulled quite a bit, not eliminated.
As for PC viruses, with a great antivirus (Avast!, MSE, and Avira are amazing free ones) and common sense, it's easy to avoid viruses. And with Malwarebytes, if one somehow gets through, it's easy to remove them.
For the OP, I recommend still getting the PS3 version. Next to the PC version, it's the best one available because it has the least amount of issues and better performance when compared to the Xbox 360 one.
