i had the same problem and was looking around for a new notebook. ihad some performance issues with my previous one, lackness of gpu proccessing and couldn't run multiple monitors at the same time for a long time, i wasn't able to calculate molecular foldings and handle very big chunks of data at the same time with it, by the way that machine had a first-gen i5 and nvidia gt330m (1gb of anciency). so i ought to buy a new laptop; my little goliath.

anyway this is what i am trying to say: define your needings then go shopping, or ask with that way.

my needings was as yo can figure, was listed above. so i bought an lenovo a z5070 < http://shop.lenovo.com/us/en/laptops/lenovo/z-series/z50/?sb...: >

you know there is a huge scandal and they are trying to cope with that with giving huge discounts! i think it is a good time for buying a lenovo, if only you'll run it as a linux box. by the i hate windows and i'm so lucky they don't care. i think windows should be a keyboard company, their keyboards are definitely awesome. < update was for keyboards >
