laptop buying uncertainty

I am interested in buying a laptop mainly for playing games but i dont want to spend much money
well i was looking at the alienware 51m whatever it is but that is rather pricey
well could someone who has it tell me what they think about it
with my config it was 2500 with 3 year warranty cheap processor.. no point in getting good proc on 2100ram

and also i heard that there are clones out there for like under 2grand. could someone point me somewhere or tell me about something please because i dont want to end up with a crappy cheap laptop heh
