If you are getting a laptop for gaming, then be prepared to play in low-res and with most of the effects turned off. If you spend at least $2000 you might be able to run new games at good quality for about a year.
You can get a comparable desktop for $600 though, so please understand how much you are paying for portability, and if it's really worth it in your situation!
I have a desktop that is comparable to that alienware laptop, and it can run games OK but not great...
you said desktop would be better... so what would be the best gaming desktop?
actually, all i care about is the price (plus minus). how much would a good gaming pc cost?
