So I'm willing to buy a new desktop for me, and I'm building it in site www.cyberpowersystem.co.uk . I chose i3-3220 as a CPU and HD 7850 2gb as GPU. Is it enough to play Dayz (ArmA 2 mod) , Minecraft, BF3 , League of Legends. Also I want to make videos with this system, will it render the videos fast, or should I chose something else? I chose those because my budget isn't big . At the moment as it is configurated it costs £588. Any opinions?
