@Tech Inferno Fan: thanks for the reply. So basically i have to replace my monitor, am i correct? Also the other options require an external PSU to power up the video card, right?

Incoming wall of text, sorry about that Maybe i did not give all the details of my setup. Existing hardware: 1. MBP 17'' with switchable graphics (Intel HD 3000 and AMD 7650m) with MacOS 10.9 with latest patches 2. Thunderbolt display What i would like to achieve: 1. Video card upgrade using e-gpu without investment in a new display (means i would really love to reuse my existing display). 2. An external enclosure which will hold an NVidia card (GTX760 or above) without having an external PSU (and as far as i understood the ViDock has a 200W PSU which would be enough for the GTX760 which is rated at 170W) Based on the research so far the TB display works on Windows ( AnandTech | A First Look at Thunderbolt on Windows with MSI's Z77A-GD80 ) and has an "usb" audio card. Because the laptop has an Intel GPU then Optimus and compression would work as well. What would not work under Win EFI boot is the on-board sound card (which is really not a problem). If i could completely bypass Windows and make the whole thing work under Mac OS it would be perfect. Based on the above what would be your recommendations? Can i achieve what i want without changing the laptop or the display? Thanks a lot! Edit: the video card can also be an AMD one.

My Macbook has an AMD 6750 discrete card and an intel gpu. In your case (i see you have a 750m) can you use gfxcardstatus to toggle the e-gpu as primary video card? Edit: i was considering a ViDock 4 Plus Overdrive (Two 6-Pin/320W/329mm) since i already have the Express Card slot in my MBP (but i could give a shot to a TB enclosure although as far as i understood the performance difference is not that big). I was simply wondering if already having a discrete GPU won't be a pain to get over (and require a windows installation + disabling the AMD card). Also, i am currently in "reading" mode before making a buying decision (i will however post here before i make up my mind in case there are some unanswered questions).

I only use OSX so that won't be a problem. The reason why i am asking is that i have a switchable graphics MBP (17'') with TB and i only play under OS X. I was wondering if the e-gpu can be used to render games (you can try playing SC2 which has a "free" version).

Hello, Thanks for the reply. Can the card be used to render any opengl game? Also, if i understood correctly the architecture is: laptop - tb - enclosure-external display (hdmi or dvi). Am i correct?

@gothic860 is the card usable in Mac OS 10.9? Have you connected anything to it? Can the signal be rerouted to a TB display? Thanks a bunch!
