I want to buy a PC that runs 99% (?) of the games of today?

Intel Core i5-4460 around 200€
Asus B85-PRO GAMER LGA 1150 around 110€
Asus STRIX-GTX950-DC2OC-2GD5-GAMING around 210€ (you should put half your whole budget on graphics card)
Kingston HyperX Savage 16 Gt KIT (2 x 8 Gt) around 80€
Crucial BX200 480 Gb SATA III SSD around 150€
ID-Cooling SE-214X around 30€
Cooler Master Silencio 550 around 100€
Corsair 600W CX M around 90€
Windows around 27€-150€ or just go free linux.
That should be around 1k€
But I would wait till rx 480 has come on market.
Plus you didn't said if monitor and keyboard and mouse should be included.

Yo soy de España tambien, donde tienes pensado comprarte el pc? en tienda fisica tipo pcbox, pccomponentes o amazon?
No te guies mucho por lo que te dicen aqui, ya que el precio varia de un pais a otro, por ejemplo el del comentario de arriba te pone una 950 en el presupuesto por 210€, cuando en pccomp por ejemplo esta a 180€
PD: monitor teclado y raton entran tambien en el presupuesto o solo la torre?

Don't ever consider apple products for anything, never buy that garbage!

My friend is selling a good PC for 300

Well, you're going to want Windows to get as many games as possible, and I'd recommend i7, 16 GB RAM, and at least a GTX 9**. Unfortunately, you're rapidly cruising for over 1k that way. Also, $1000 is vastly different from 1000 Euros or 1000 Pounds, so you might want to specify.

JUST DO WHAT I DID AND BUY A GT80S -002

THE LAPTOP IS AN ABSOLUTE BEAST
WINDOWS 10 has amazing system management and memory management and runs everything best

Don't get a PC right now. Both Nvidia and AMD are releasing new GPUs at this exact moment, jumping from a 28nm(which they have been stuck with for about 5 years now) node size to 16/14nm node. That's enough to render previous-gen cards entirely obsolete for new builds.

Wait for a month or two until market demand for these new cards stabilizes.
