Build gaming PC rate the build?

I'm gonna be building a PC soon for games and I'm thinking of probably playing Battle Field 4 on it some other games I will definitely play are Skyrim, Chivalry, Minecraft, Loadout, Team Fortress 2. So I've chosen some pieces but I'm not sure which are better than others I'm on a budget of £590 (Pounds) For everything including monitor, keyboard and OS. So far I've built one PC but I'm not sure whether it's that great or not. How would it perform playing Battlefield 4? And Skyrim? On that "built" pc I haven't chosen RAM. Please say how well the "built" PC would be cos it is great for my budget. And "make" one as well with the parts and I'll check if it's in my budget. Please if you are gonna make a PC make one without any incompatibility's.

Wich rpg game should I play on my low end computer?

I'm a new gamer that has only played some rollercoaster tycoon, the sims and pokemon. I have just started to get into actual gaming. I've tried wow, but my computer couldn't handle the online thing. Then I played minecraft for some weeks but I got bored with it. I like training stats, getting quests and planning a strategy. Since a week I have been playing morrowind. My computer can definetly handle it but not something more advanced I think. What I don't like is all the hard names and history. I have been reading a lot about it on the internet but I just can't seem to get into the story. Maybe because I have never liked anything medieval, and the names and history remind me so much of anything like that. Mind you, I do like lotr stuff but I think it's the fantasy thing I really like about it, elves and wizardsss! So I do like the scenery and monsters a lot.
Since I'm a new gamer I have no idea where to start, I have never been into gaming and I can't play any new stuff. So anyone care to help me out?

Exploration based PC Games?

I'm looking for a game that's mostly based on exploration. Something kind of artsy that I can just sit down and immerse myself into. I don't want any suggestions like Skyrim or New Vegas or Minecraft or anything. I want something that's new and completely foreign. A game that's eerie is some parts but has amazing architecture and scenery in others. I'm not interested in Dear Esther, I want something more open. Proteus is a good example, but I want something more than that. I don't want a game that I know I'm completely safe in, if you know what I mean? I appreciate any suggestions.

What is a good video editing software?

So I recorded a minecraft video with fraps, used Windows Live Movie Maker to edit it a bit and saved it. This compressed it from a 20gb file to a 3gb. I was told this was to big for youtube so I got handbrake and compressed it down more. Now my video can only go to 360p.

I have no money atm so I can't purchase anything. Any ideas for a better way to record, edit, and render/compress files so I can get at least 720p on youtube? Any advice would be greatly appreciated.

Which desktop computer should I buy?

I need a desktop computer that is great for Minecraft, surfing the web, checking my email, etc. I was thinking about getting an Apple iMac because my friends were recommending it, but my brother and sister both say an Apple iMac isn't good. Someone help!

Why is my minecraft not using all its ram?

Recently i got a used computer and I play minecraft and make videos of me playin mc. Anyway I noticed it has 2003 mb dedicated to mc but it only uses about 15% of that (about 300mb) and it keeps climbing to about 600mb then goes down to 80mb and starts all over again… Is this a setting or a flaw with minecraft cause everyother game works perfectly without lag
