If you're gonna buy a gaming laptop, then the 40GB SSD seems a little tight. Anyway, if you really want a lap that has a SSD then you gotta stretch your budget even more... unless you're looking to splurge all your money on the SSD and give up on the other components.
I'd say drop the SSD. It isn't really that much worth the money given your strict budget. Also good configs on a 17 incher will cost you more. You gotta settle for a compromise.
Check the Dell XPS 15 with the following custom on its 47k version:
-Core i7 2630QM
-6GB memory
-2GB GT 540
The rest are the default components on that version. It will lack the bells and whistles but for a true gamer I guess that would take a back seat in the face of performance. Also the 540 is slower than the 555 but only a tad slower. The difference will not be glaring.
With this config you can play on max resolution but with other visual effects like AA, AF, etc turned to medium. It will definitely look good, if you that's what you're bothered about. And the best part: It sets you back by only abt 58k, which is within your budget. You could probably buy a good keyboard-mouse combo or a gamepad with the extra dough. Or you could consider a 9cell config if you're the kinda guy who's on the move a lot.
There is also the HP dv-4 3000, but it's got only a 14" screen(which I'd say is a big minus for a gaming laptop) and no Core i7.
As for the rest, good gaming laptops that come close to your reqs are way above your budget. I did a market search myself for a gaming laptop only recently with a budget of 80k and couldn't find a lap any better than a more buffed up custom version than the XPS 15 I've suggested for you.
