^^ The OP seems really stuck on brand and doesn't really understand performance issues at all.
I agree, that lenovo would kick butt, however this guy obviously doesn't really need a good machine at all. Best let him buy his sony.
His priority is that it is branded and "works". God only knows why he is on this forum.
P.S. Both the Ebay sellers I listed have huge good feedback and offer warranty on the goods which are new "open box" machines. I wouldn't suggest something I wouldn't go for myself.
I bought an inspiron 15R n5110 (the one with the gt 525m) proof: see my feedback

The gt 525m is exactly the same GPU as the gt 550m with a lower clock (see notebookcheck) I overclock mine, but even on stock it pillages games.
Anyone else reading this thread looking for a great value gaming notebook need not look further than this.
