Well first of all, "Bang for you buck" in the computer world often times results in a crap machine. I'm not a dell fan at all but i must say they make a solid laptop. I am very partial to compaq laptops. They are very good about keeping their warranty true and will give you a quick return on a problem.(I know this for a fact. I had a HDD die, common in laptops from what I hear.) The R3000Z (think that's the rigth model) looks like an outstanding piece of machinery. You can spend about 400-600 bucks on it and make it really top of the line for a laptop. So you are looking at rougly 1100-1300 dollars. I would upgrade the video card and the processor and I think anyone would be set.
Toshibas are great laptops as well.
Voodoo would be my choice, those are pricey though. Great gaming machine with great battery life. Also they just look cool.
Alienware laptops are crap. A friend of mine bought a 2.8ghz intel and got sent a 2.4ghz! He also noticed it was painfully hot and so he sent it back and had a HUGE amount of problems with the return and after a month he still didn't have a comp! So he got to talk to a head offical at alienware and he told him to buy a dell or something because their laptops had a big problem with overheating!
Hp makes good laptops, but not quite as good as compaq IMO. Wierd how they are basically the same company but Compaqs are definitely differnt.
