Another better-than-you-already-have laptop.
Isnt ps4 coming out soon anyway (release is about 7 months away)?
After it comes out, no one will care about ps3 anymore.
So I can propose another option, lol - ps4.
Depends on what kind of gamer the OP is. A smart one. A rich one. A hardcore one. Something else. Both. All the above. None..ok you get the point.
I personally would NEVER buy a console on release. First, there's usually not a lot of launch titles that I usually like (usually movie crossover titles, garbage ports). Second, you'll be buying it at its highest price. Third, you also are buying the first edition of the hardware aka possible issues. I usually wait for the 2nd price cut as well as possibly hardware upgrades.
How I see it is, do you really want to game on the laptop? Laptops with decent graphics card are much much more expensive than whatever the PS4 will ever be. It'll be at least 1k (and this is a low number Im pulling out of the air). Depending on the games you want to play on the computer, geting a laptop with integrated graphics can be useless if meant for gaming. Also consider what other games you'd like to play in the foreseeable future too, making graphics cards a pain to deal with when gaming on a laptop and not a desktop.
If you haven't had a current gen console (Wii, PS3, 360), a PS3 is the better choice for gaming than the laptop. The PS3 will be decently priced with enough games to last you for a while. Some sites I've seen said there's going to be a bit more price decrease on PS3 due to the PS4 coming out Plus, some games would be cheaper as they are greatest hits games. Are you serious about being a hardcore gamer or is this going to be a hobby?
Those are my opinions. Rest is up to you on how much money you plan on spending. Whatever you choose, good luck and hope you the best
