Selecting the 770 model would be just perfect, i just don't see the reason to give extra 300$ just for the lasy 130MHz more.
More. That's giving the wrong money just for the brand. Again. It's stupid. Go at www.gamepc.com -> http://www.gamepc.com/shop/custom.asp?rig=noteb5300
choose the 770 model for the CPU
2x1GB DDRII 533
make the hdd a 100GB 7200 rpm one
add a TV Tuner
and an Audigy2 ZS
and an 802.11G with bluetooth
and a Logitech G7 cordless mouse(best for gaming)
Sound like a 770$ less than the Dell. I'd say paying less for a better machine is cool enough.
