You need a supercomputer to run this game

[Swoosh So]

£400 and you could build a pc that will play stw2 using parts from the old one probably cheaper in the usa as we pay VAT on everything here. Im talking about playing it well tho.
Around £130 for a quad core processor or a good dual core.
Around £80 for your 4gb ram.
Around £120 for a decent graphics card such as the nvidia 460.
Around £80 for a decent mobo (you can get cheaper ones also around £65).

You can probably convert those prices in pounds straight to dollars we get ripped off for everything in the UK.
