Well,what we we can say there are a lot off different products in the market.
You can hear that Acer is cheap with high spec provide but quality bad~But they did some of the Acer user use it without any complain.
Just like there are people say that ATI GPU is provide with high performance in a low price then Nvidia GPU.
They say that ATI is bad in quality and Nvidia is good.....I think it's depends your luck....nothing can be perfect...
Just get which suitable your choice and your budget. If you want the best then don't complain about the price,pay more and you should get the better
