yes it is
When a budget of 500 dollars can build a good gaming PC. This can be build piece by piece.
I would reccomend an alienware gaming pc.
currys and pc world are good
When it comes to building/buying a good PC gaming rig I think Dell is the best because they bought Alienware which has always had the best pre built gaming rigs around.
No offense, But do your self a favor and get a desktop gaming PC not a laptop. You would get a better PC for less money
Try a custom gaming PC company like Ironside Computers. Speak to someone there so they can recommend exactly what you need. Their website is IronsideComputers.com
GeForce GTX 260 or ATI 4870 are some of the better cards available today while not being bank-breaking forerunners, and both are good choices for a gaming PC.
Ebay is a good site for gaming.
Its actually the best for gaming,but I would suggest the Q9650 core 2 for gaming.
pretty decent, but not good for high end gaming. I hope you at least have a ATI or NVIDIA GPU and not an intel!
I would say a good gaming laptop definitely. Most games for 360 are also made for PC but there are tons of popular games that aren't made for xbox and only PC.
