That's probably not a great choice. My lappy has Radeon 3650, which is a little faster than the 4570, and Eve on full detail is too much for it. The 1366x768 screen is possibly a bit low res too.
Hmm I have to admit I`m wary of buying 2nd hand/refurbs
Refurbs can be very good value, although even going that route I think you'll struggle to get a suitable laptop for £500.
Dell Outlet is good if you're wary, anything with cosmetic damage is flagged up as 'scratch and dent' so you can avoid those easily if you want. Just looking right now they've some refurbed Studio 17s for about £600 with an i7 processor, Radeon 4650 1GB and a 1600x900 screen.
