I have a budget of €500 and I am looking for a gaming laptop. I saw a second hand Lenovo Y510p(i7-4700mq, 16gb RAM, Dual GeForce GT 755m SLI) for sale on eBay and I am considering buying it. Are there any other more powerful gaming laptops for €500 that I could pick up second hand online(or new if possible) that will deliver better gaming performance. This laptop is quite old so I don't know how it will fare on newer titles.
