Hi new to this site and eGPU. Read for three days strait. my learning curve seems to be still quite high. I have a Acer 8951g with a i7-2630qm sandy bridge with 16GB. there is a spare ePCI slot free (for gps module). Can i use this port. also confused about tolus values and using setup program. Will this work on acer 8951g spare ePCI port. Will i need setup program. i have nvidia optimo. Can the setup go from internal gpu on the road and external at home with min setup each time. What is the best system and card i can use. (internal gt555m) Is it worth it. Will the external card have alot more gain running with restiction compared to my gt555m Thanks
