A new pc

So because i'm borderline retarded i would highly appreciate someone's assistance in helping me build/buy a new pc, i want to get back into renegade and the old pc i used is kind of buggered, so i thought it would be easiest to just start afresh

i want to be able to play renegade, starcraft and maybe some of the new games that are coming out/are out such as outlast/the evil within etc etc, those newer games are probably the highest standard of games i'll use to play

so the help i need are basically a list of parts that i'll need or a direct link to a pc that i could buy, i don't want to be spending too much, but i don't want to just waste away money on the cheapest parts for a pc that won't last.

i would be eternally grateful and appreciate it hugely! i miss the server and playing renegade, so yeah

many thanks in advance, and hopefully someone can help (i'm serious i'm extremely stupid, you'll have to explain too if you have the time)

I bought it on Cyber Monday, so all the parts were a little cheaper.

I recommend using PC Part Picker or use the domain of whatever country you are from. EDIT: I see you are from the UK, you can use this

Another good website to check out is the buildapc subreddit lots of people give tips and if you use pcpartpicker then you can post your finished build on there and some crazy pc nerd will make it better for you.  Personally I put mine on there and somebody increased its performance and saved me $90!

If you have any questions, I researched a bit before buying the parts (of course!) and I am willing to help

Also I haven't built my PC yet, am waiting until after finals to do so, so I can't tell you how well it works haha
