Help needed for a computer noob :P

[Noir_Proxy]

Hi everyone. I am currently looking to buy a computer from here for under £700. Sadly, I am not very good at understanding the system specs of the machines and I was wondering if someone could help me.

I am wanting to purchase a unit that can play Dawn of War 2 and Starcraft 2 on max settings as it's all I ever play I am currently on a laptop with a GT 8600 and I can only achieve medium graphics and some on high if I want some framerate lag at times.

I was looking at the Titan Xenomorph and it seemed like the best choice? But you guys will obviously know better than me. Is there a better one or did I pick the right one?

Thanks!

I was planning on getting the Geforce GTX 470 1028MB, so is a 5770 better than that? Between the Predator which is on sale and the Xenomorph, which one would you guys choose? If you wanted to play those games on ultra? I do have £700 to spend on it after all

Also can the motherboard fit two cards for in the future?
