umm...for a laptop, its usually whole configurations...dude, i don't think u can, you know, buy a mobo and assemble a laptop urself.....like a desktop...if u mean the best gfx chipset, i guess it'll be the geforce go 7800 when its released.....till then it has to be the go 6800.....chk around for laptops with tht video chipset....might be the vaio notebooks hv it
rite now go in for lappies wid 9x5 chipset and at least ati radeon x600/x700 class grafix chipsets (eq geforce series). the 9x5 supports ddr2 ram modules. don't go in for the onboard gma. get a lappy wid a dedicated grafix card.
ps: folks he probably wants to buy a laptop and is asking for the config to go in for! obviously everyone knows that it aint easy here in india to assemble a lappy!
