As the title says. i am going to build my 1st ring in summer, but i try to catch as many discounts as i can because i have a kinda tight budget. I have seen the great reviews about G502, but i am not really sure if it is worth it, as i have also found G602 and razer DeathAdder Chroma for the same price (35 dollars). Should i buy it? (I am going to use it mostly for FPS games, such as CS:GO)
