What's the Best Gaming Pc for me to get?

I'm getting (or want) a gaming pc. The one atm just won't cut it so i need a new one.

I have looked everywhere for something with what i think i want but i'm really don't know what to get. I wanna play games like Total War, Civilization 5, Sim City, Sims but also stuff like 7 ways to die, the forest, Arma 2, 3 and DayZ.

I really don't understand pcs that much and have always been a console gamer and although i have read numerous reviews on why it is best to build your own i really don't want to. I want a system (low-med) capabilties that i'm able to upgrade as time passes, where i can then learn and understand more over time about how stuff really works.

i'm thinking about getting an Alienware X51 R2, as they are apparently good for console games?

i reall don't know which to get, i think i want something like:

-intel i5, (i have an i3 atm and don't think i need an i7 but would like to be able to upgrade in the future)
Nvidea or amd (would prefer nvidea from what i have read)
1TB/2TB (don't know really)
Power (don't know)

this is the problem i just don't know what i need and where to go.

any help would really be appreciated and just so you guys know i will have around £500 - £800 pound to spend but have no, monitor, mouse, keyboard, anything.

is it even possible with this amount or am i better of getting more cash and upgrading or anything.

Thank in advance

Added (1). Also i would like to have GDDR5 is possible.

What Computer/Specifications For A Computer Would Suit Me?

I want to play games like Minecraft/Call Of Duty/League Of Legends.

I want to spend from 250 to 350 pounds. I do not want to spend more than that for a computer.

I'm not too concerned about high end graphics, but I also do not want a slow desk top.

Will I get a fine from Walmart?

Ok so heres my story, I'm 14 and I got caught stealing a Minecraft toy for my little bother. They took me in a room and asked me a bunch of questions. Eventually I had to call my older brother to pick me up and one of the guys said I'm going to get a fine, but the thing is another guy before said since it's less than $40 I won't get a fine and this might not go on my record… Another thing is a while ago my step-brother got caught stealing from Target and they said he was supposed to get a fine as well, but he never got the fine. Anyways it's been like over a month and I haven't got a fine so I wanna know 2 things.
1: Will I ever get a fine or are they just trying to scare me so I don't steal again? (Which I won't do again)
2: Will this go on my record and if so, how will this affect me in life?
I live in Las Vegas, Nevada by the way.

Should I record my voice with a gaming headset or a pro mic?

I have a YouTube gaming channel. I've been recording with my new Apple Earbuds that come with the iPhone 5 or the iPod Touch 5. I'm travelling this summer so I will buy some stuff.

I will buy the Razer Kraken Pro (green with mic). Should I also buy the Blue Jeti or should I keep my money and record with the Razer Kraken Pro mic?

I'm small and just starting on YouTube. I have like 120 subs.

If it matters, I upload Minecraft (mainly), COD, Skyrim, Left 4 Dead 2, and maybe some League of Legends and other games in the future.

My gaming laptop ran games cleanly yesterday, but now they lag today?

The games I played were

Hawken (I think that was the game's name, the one with mechs)

CoD 4: Modern Warfare

Minecraft

PlanetSide 2

Now they all have the same kind of lag (after ever second or two there's a second of slowdown then back to normal then slowdown etc etc etc)

Also my laptop (windows 8.1. Still this gaming one) started making random noises once in a while for no reason (that usb sound one… Or the one where there's a confirmation popup if you were installing something) but there were no messages at all…

Then when I would be typing it would just disselect the typing thing and I have to click on it again.
I only had this laptop for a few days.

The only things I remember downloading today where the GeForce Experience, Skype… And then CCleaner(but I downloaded CCleaner after I found the problem because I wanted to fix it with CCleaner… Didn't work though)

Added (1). What I'm getting are lag spikes of death. Like in minecraft where you lag every 2 seconds… Except I get that in all the games on my computer. I tried fixing whatever I installed that made it lag (I'm guessing the NVidia GeForce Experience drivers) by restoring the system but the only problem I got was all my desktop icons deleted, windows apps all have to be re-downloaded and all of a sudden it says my windows thingymajig is expired on the Store App.

Can snow lay in minecraft?

Iv got a big minecraft town and would think it would look great it snow could lay all over it. Is this possible now or in the near future.

How to lose weight and get back into shape?

As of now I'm 14 years old 140 lbs and I'm at least 5'3. I have not been a big kid all my life, I'm actually not BIG but I'm getting there. Anyways I started a really serious habit of playing Minecraft, Cs: go, Dota 2 for 16 hours a day (about a year ago). Every day, also I've had a concussion recently (6 months ago) So I have not had any physical activity since then to this day. I'm a shy kid even around my family and I'm embarrassed to say to my mom that I'm tubby and want to lose weight because everyone thinks I'm skinny like I have been most of my life. But I'm at the point where if I run up a set of 12 stairs I start to feel out of breath like I just ran a 5k. With no access to gym equipment (I'm also going through financial troubles) besides a treadmill 5-20lbs weights. Not only am I doing exercise to lose weight but to get another habit into my life because I've stopped doing homework and I'm rushing to do it at lunch, in homeroom and many other places. I've started planning this now because it's Summer and I'm finding out now that my grandmother signed me up for soccer (my favorite sport) that I'm really good at but I'm just not in shape to even run a lap around the track. I just need some easy diet, sleep, and exercise routines. I don't want to be ripped though, only toned and get rid of my new born moobs and gut.
