An R7 240 is good for the cheap price of $60 USD. It's almost 2x better in performance than your typical newer integrated GPU.

First of all Minecraft is a low resolution graphic game. Next if your having lagging problems that's nothing to do with the computer, that's all down to your operating system (WINDOWS) once you get that into your head you Just might do something about it. For the passed 8yrs I've been telling people like you the same thing. Minecraft was/is a Linux game that Mickysoft bought for 2.5 billion dollars, like they bought Linux Skype for god knows how many billions of dollars. Micksoft have lost million and millions of users they all moved to using Linux. Mickysoft in their infinite wisdom thought if they bought Skype they would get all their users back then they thought they would buy Minecraft and get ever more deserters back into the windows money grabbing fold, once people learn there are other operating system then they move to them. Now the thing about using Linux there's umpteen alternatives so when Mickysoft bought Skype and Minecraft people moved to there alternatives no way are they going to be forced back into the Mickysoft fold. There are 10 minecraft alternative games there are 6 skype alternative, With Linux users they are spoil t for choice. So now you know that your problems are caused by window…
