i bought a gaming laptop a few weeks ago from novatech. it's the x80, the one with the orange trim around the edge, over your budget though if you could be tempted it's a fantastic laptop. but my son has the x60 from them and plays football manager live on it just fine. it cost about £600 i think. i am not a techy geek but he plays fm live on that as well as things like half life, bioshock, portal with no problems.
