I have an Asus and I love it.
I also bought an Asus in January. Works fantastic. Ran me about $1800, which is significantly more it cost to build my desktop, which has similar specs. I needed a quality laptop to keep me occupied during extended chemotherapy sessions, and you can't just throw together a gaming laptop like you can a desktop. My other laptop is not made for gaming and gets pretty warm just from playing video. The Asus stays cool no matter what game I'm playing so far, which is reassuring.
check out themalake laptop coolers. they help a ton. will extend the life of your laptop by years.
I have a laptop cooling tray. Not Thermaltake, though.
My Asus model number is G75V. I play a whole lot of games, but I think the most graphic intensive games I've run so far were Skyrim and maybe Resident Evil 6. Both ran flawlessly on maximum settings. That said, I'm perfectly content playing games with textures scaled down, so this should last me quite a way into the future. Graphics rank distantly behind gameplay, story, amount of content and ease of control in order of importance for me, so the next few generations of games that release should run pretty well with the settings scaled down, if I need to. I tend to get 5+ years of solid gaming out of a computer, usually only upgrading out of necessity or convenience. I'm not the type of guy that buys a new video card every time one is released.
But having one that's capable of running beastly games and making them look beautiful is nice, I won't deny that. If I had unlimited disposable income, I'd definitely upgrade every chance I got.
