Building my own PC

[Chad]

If you somehow 'obtain' the OS without it damaging your budget, I'd say this: http://uk.pcpartpicker.com/list/dYhLPs
*** Same build as above but without optical drive and sound card: http://uk.pcpartpicker.com/list/7PGYgL ***

If you are buying your OS, I'd say this: http://uk.pcpartpicker.com/list/ncF9NN

There isn't a huge differance between builds, but the OS one doesn't have a optical drive or sound card which you don't need but are very handy to have. But if you use Steam for games and have no use for a drive then don't have one. And if you always use headphones you don't really need a sound card.
I believe all the builds are around €700 but they may be under/over because I'm in £.

Looks great. Yeah. I download all my shit, never use my optical drive. I think a sound card is uneccesary as I can just purchase some speakers.

Thanks for the suggestion, I may just use one of these (altering stuff slightly)

Yeah man, that build will run all of the most recent games at a decent setting with good FPS. I'd still say keep the main components that I suggested like the CPU and GPU (Or swap it out for a slightly better one if you can afford it) and if you need add more RAM. But for the budget you have I'd recommend that or something very similar.
