The performance is far gud, its very interesting to use Win-8, the only dis adv is that the graphics card which is an inbuilt is not that much effective for some HD games, Some times it gets heated up very fast, but the start and stop function is very gud and very fast too. I am using a slight different config; ie; i had installed 4GB RAM, which has been advised by the shopkeeper, the sound clarity is always best in this, videos too. I request you people to install a best anti virus software for this machine. rest all very gud.
