IPS panels are not good for gaming.
Get a monitor with fast response time and good contrast ratios. Samsung PX-2370 is a good gaming monitor in your budget
I would take exception to that.
I game on an ips monitor without any problems. Which one...well....Dell U2311H
I've read that but I've read many posts at thinkdigit forum and people using U2311H are saying that they are getting pretty decent gaming performance.And as you can read in my post I'll be watching a lot of movies too.
And also as I'll be connecting it to my brand new Dell XPS I prefer a Dell monitor
I would replace "decent" up there with best. Awesome colours and contrast on this ips without any ghosting whatsoever.
But for movies. Its a MUST buy.
I would suggest Alienware OptX AW2310, to go with the look of your XPS

But check with Dell if they are selling U2410 in India, also based on IPS Panel and has got HMDI, when I bought my Dell S2409 with them it wasn't listed in their site but they quoted that model in their conversation. So call/mail Dell and check if they have U2410 here.
Both of them are around 25k.
I was eating so I couldnt type much. Wait till evening for more IPS spamming.
One thing is for sure if you have 18k to spend and still ditch an IPS panel then well...wait for a bountiful of regretting later on.
