Hi all, Very new to this and anything tech, hopefully I'm not posting in the wrong place, feel free to nuke if so... So... After reading all I can and hassling people extensively on reddit I have got close to what I think is an egpu I can get my head round and build. Bear in mind I didn't even know what a riser was before reading up on builds. Or a barrel plug. PCI I had heard of before... So so my parts list is: single fan 750ti card Akitio enclosure 120w PSU with correct plug. Im pretty confident they all just go together and work fine... So on to software... I installed 64 bit windows 7 a while back on my rmbp 2012 (650m) and have read something about needing EFI mode which is only from 2013 onwards. I am aware I am sounding like an idiot here. I've also read about some software by a user here that you can buy which might help? Basically I'm lost at this stage, reading all the guides only helps a certain amount as I have no real clue what I need to be checking/what instal I have so I hope someone much wiser than myself can point me in the right direction. Im aware I am clueless, but believe nothing's impossible with a bit of research and a friendly hand... I hope this post is ok. Apologies if not.
