Using this laptop for about a month now. its a beast in terms of performance. Noo heating problem.for high end games graphics card performnce is very good with low and medium graphics setting. at this range this is the best deal you can get by a mile. great performance, supet design and such a measly price tag. granted. there are a few sharp edges, but I do not think they matter. speakers are good and loud. I use heavy graphics software like autocad w.orks without any issue. I have installed windows 7 without any issues and downloaded drivers from lenovo website. its worth of money.
