Alpha Clients CPU/Memory Usage :(

So on my laptop (I'm a student who is not trying to invest in a desktop simply to play a game), the new client takes up so much and basically lags slightly when up from taking so much resources to operate. So I wouldn't be able to do much multitasking with it open. When in-game using the new client, it is better if I close the client and leave only the game open otherwise I get fps lag from it trying to run the client and game together. Which means I would be relogging after every game. If this is going to be the new client, will it be closing like the current client does majority of the time and reopening at the end of matches? I love the new look but damn, I'm sacrificing a lot of resources when I personally care more about the gameplay than how I am getting into the game.
