As I know that for a gaming purpose we need a high speed and best performance laptop, but there is very costly laptop exists but we can’t buy. so we purchase minimum price of laptop and modify it through the extending its RAM(memory) e.g. lets say it have 2GB or 4GB ram and it has more than 1 or two slots then we replace its ram and extend it into 8GB or greater . If Laptop have Intel HD graphics then it works more than extremely good or can say it should be differ from old one laptop, because due to this ram memory and processor speed combine together be perform best result.
