Hi so i have an alienware m14x R1 with and intel i7 2670QM, 12GB of ram, and more importantly a Nvidia Geforce GT 555m graphics card(2GB model i believe) Im looking to add a eGPU since the computer is fantastic with the exception of the graphics card that is pre installed. I'm new to the whole eGPU thing but I do have a bit more info that might be useful. I dont have lightning or expresscard, but when looking into my computer it seems that under the battery there is a wireless adapter and what seems to be 2 more pcie slots. I really need some help as to what adapter I should buy, a nice video card for gaming, how to set everything up (youtube doesn't show too much on eGPU's as far as iv'e seen D: ), and possibly an encloser? Thank you soooo much for your help
