Help with 1st build

[z6f]

I'm building my first ever computer soon and I would like some advice.

My budget is £300 and I want to do some light gaming on it. I want to play games like Portal, Mirrors Edge, Cod4 etc. Playing modern games on medium would be a nice thing too.

I currently have 3 builds but I don't know which one to purchase.

My questions are:

Which is the best for gaming?
Can I get better components but get them cheaper or relatively cheap?
Most importantly, will the PSU work with everything?


Thanks in advance.

I think the second is better, those components are pretty good.
