Which laptop to buy?........?

Have been plannin to buy a laptop for quite sometime now but havent really been able to decide upon which one to buy.... A friend of mine suggested lenovo over the others... M not really sure if i'd go with it unless i'm taken into confidence that the money i pay for it is really worth it.. Plannin to dole out abt 50k on this... Lookin forward to one which has a dedicated graphic card, a good processor.. Do u think i can have one with a blueray drive for this amount?... Guys plz do come up with a few suggestions... Don't mind the brand as long as the laptop performs well......
