PC Build for Specific Game?

[n300zxtt]

Hi I am looking to build a pc, but its for really just 1 specific game.

The game is Euro Truck Simulator 2 and its req the following specs.

Recommended System Requirements
Windows 7/8, Dual core CPU 3.0 GHz
4 GB RAM, graphics card with 1024 MB memory
(GeForce GTS 450-class equivalent or better)

I want to be able to run it on full spec connected to my 37 inch HD TV. I have been reading up on bits for the build for days and my head is about to explode.

Now i think im set on a GPU card HIS HD 7850 IceQ X 2048MB GDDR5 PCI-Express Graphics Card (H785QN2G2M) and CPU
Intel Core I5 3570K Ivy Bridge 1155 3.4Ghz 6MB BX80637I53

Allthough i may only need the 1024mb card like a PowerColor AMD Radeon HD 7850 PCI-Express Graphics Card

As you can see im starting to loose the plot. can somebody help me with a suitable case, motherboard etc. I am looking for WIFI connection, either in the motherboard or if cheaper via a card. No idea on what Power Supply i need, but i guess 8gb ram maybe a good idea. i guess a near £500 build?

I maybe overspecing myself and spending more than i need as i have seen a good spec I7 advent Tower PC - Intel i5-2320, 8GB, 2TB, DVDRW, 2GB HD6670, Windows 7 - New ** System isn't OcUk and so to neither is the pricing ** which looks like it meets what i need?

Ohh and my son will probally migrate from minecraft on his xbox to the pc and my daughter will probally do the same for sims 3 from the laptop to it.

Thanks in advance.

This runs the game fine, would i loose much with the £399 system with the i5 rather than i7 chip?
