I was thinking to buy acer v3-571g but when i read the reviews of its gpu it was really kinda low of.So please tell me that which of these two is suitable for me & if you know any other please recommend me it also under my budget.
It all depends on what you want by "gaming"
the company i work at has plowed through so many HPs we will never touch them again. Based on that alone i would go with the Acer machine. We have had great luck with Asus, MSI and Acer.
