I have the last gen one, cooling it on sucks balls man. I get 80c cpu temp playing portal 2 for 15 minutes. Hence I built a desktop.
If you want a small gaming laptop I recomend the sager/clevo 11 inch laptop.
It costs $776 for the base price. comes with an ivy bridge i5 and 650m 2GB model(a bit weaker than a 550ti but 2x the vram so trade offs, and it can OC to > 1ghz).
For $100 more you can add the quad core mobile i7, it will add more heat but also more preformance in games that use all 4 cores and like video editing or code compiling. May or may not be worth it.
for $25 more you can add IC Diamond Thermal Compound - CPU + GPU. It will lower temps so its worth it imho.
for $80 you can get "COPPER COOLING UPGRADE - Extra Cooling Copper Heatsinks Applied to the Heatsink/Heatpipes (XPC Service - requires shipment to XOTIC PC: will add to build time) " I'd say its worth it, but thats just me. My brother doesn't have it on his cause they didn't offer it when he got it and his does just fine temp wise but it does have the special thermal compound they offer on it and a cooling pad.
Comes with 8GB dual channel ddr3 1600mhz, can be doubled for $80.
Plethora of hdd/ssd choices, this base model comes with a 750GB hdd.
And many other options that I don't feel like listing because theres a LOT of them.
Also it doesnt come with an OS. for $80 they will put one on it. Kinda expensinve, but thats gaming laptops for ya.
