Is this good enough laptop....? please help...?

Yes, definitely. That's one of the fastest mobile processors and best mobile graphics cards on the market, with a decent 6GB of memory. The only thing that would really make it better at this point is if it had an SSD instead of a normal SATA hard drive, which would speed it up even more. But it's really not going to get much better than that in a laptop, you'd have to go to a desktop.
