Need advice on these's pc's

[mastic]

Im looking to buy a gaming pc on a budget, seen a few links and dont know which to get. I also do the usual with torrents etc but dont watch films on the pc. My budget is £400 with P+P, or collect from manchester area.

1st one is the Aldi pc but you know what its like to get one of these ( 2 to a store and no more lol) but i dont think it will play new games with its graphics card and it only leaves £11 change out of £400 lol
