Is a GTX 940MX graphics card adequate for low-medium level gaming?

I've been offered the chance to purchase my first gaming laptop for my birthday, (I'm only 14 so I can't yet produce the funds for a good one) and I discovered the $550 Acer Aspire E-15 which contains a 940MX. I only plan on playing titles like SWTOR and other role playing games of the same level, Modded Minecraft, and possibly Overwatch. I don't plan on playing hit titles at all as I know I'm not ready for this. Is this the best possible choice I can make for under $650? My parents won't seem to nudge towards anything over $650. Also, I ll be receiving this laptop after February 12.

How do I set my home spaces in Minecraft for PC?

Got Minecraft for Christmas and I'm told I should be able to set my home base and name it and stuff but I keep getting that my command is not valid when I use the commands /sethome and /sethome home (the later is when I try to name my base). Am I doing something wrong or is there a problem with my game?

Can only play Minecraft demo?

I bought a minecraft account and played with it for awhile. Then I wanted to give the account to my sister. I changed email to hers, password to her choice and now I want it back. She can't play because it says it was registered under a different email. We switched email back but it still only lets her play demo. Ideas?

Tips on how to start my first series on my gaming channel?

Ok, so about 2 months ago I have started a gaming channel. Most of my content has been done is either funny moments of some gameplay, or some builds I have done on a minecraft-like game. By far, my most popular content is the minecraft-like content, but I don't want to rely entirely on that type of content. My channel is more of a general one, but I do focus on games where I can involve my audience in some way. So I want to try to start a series. I was thinking a let s play, but I'm not sure if that will work out. What will you guys suggest?
