That laptop has it's own dedicated video card, or GPU in the 970M, and the 970M is the best midrange discrete mobile GPU out there right now. I'd say you'll be good for the new stuff and great for light gaming for a good few years to come.
I like Panda Free AV these days, seems to perform the best in synthetic malware tests. The problem with Microsoft Security Essentials these days is that most malware attacks are designed to avoid it. Could save you some CPU time on MBAM since it's looking for both.
If you're keeping things around $200 the GeForce 960 and AMD R9 270X are solid choices for 1080p gaming. The nVidia driver experience is better than the AMD one and the cards tend to run more efficiently these days, but at lower price points like this one they can be appealing.
I tend to like MSI's cooler design right now - http://www.newegg.com/Product/Product.aspx?Item=N82E16814127844
I imagine all the people here waiting for the Bombcast looking like the hollows collected at the entrance to New Londo Ruins.
I'm watching a hockey game and checking during commercial breaks and intermission. Now that the Stars have let in 5 for the 10th(!) time in 28 games I'm watching the game less and less and checking twitter more and more. The real Dark Souls is at American Airlines Center.
The Stars have given up 3+ goals in 18 of 28 games this season.
If you play 15 on PS4 I'm doomocrat there as well :D
