errmm... this might not be the place to ask but i seriously dunno wer else shud i post this..

ok.. juz wanna know that when they say 'NVIDIA GeForce 9400M graphics processor with 256MB of DDR3 SDRAM shared with main memory'.. does it mean that the graphic card will actually used up 256mb of my ram memory and cause the laptop to be slow?

so if i upgrade the ram of the laptop..does it help? coz 256mb out of 4gb is really not much wat..zzz dunno whether i am correct or wrong..

and is 'NVIDIA GeForce 9400M graphics processor with 256MB of DDR3 SDRAM' such a bad graphic card?? becoz i am planning to buy a laptop that can runs well with autocad.. i am a engineering student..
