Yea I wasn't suggesting the op didn't do well for the budget of the parts listed but it's already a low end psu, there's worse than the 950 but it's no gaming monster, the cpu is about as low as you can go as well as the motherboard and case (outside of using a pizza box). It's already going to be a low end gaming pc as it is, maybe lower mid range at best and cutting another 60 pounds off it is going to make it a slideshow for pretty much anything other than solitaire.
No fat left to trim and if it's 60 pounds over budget in its current state I think the op would be better off with a console. They'd get more consistent enjoyable game play out of it. Either that or save up a bit, if anything I'd be looking to improve some components...
