EGPU setup: TH05 output with HDMI capture input

Hi all, have been following the forums for a while and am thinking of taking the plunge on a new egpu setup, using the following:

Lenovo T430s (thunderbolt version)
Bplus TH05
HD80E HDMI capture card (as discussed in the “Play PS3/X360 on laptop screen using new HDMI Input Express Card” thread)

I am planning to run the egpu off the thunderbolt port and pipe the picture back to the laptop screen via the HD80E. My idea was that laptop screen performance should benefit from the unrestricted bandwidth.

Does anyone see any issues with this setup? Anything to watch out for? Is it going to be worth doing it versus a standard expresscard setup?

Many thanks!

 

How about any lag from HD80E? Does it apply some sort of compression which might create some input lag and for some games that might not be acceptable.

 

Well, there has been quite a bit of discussion on this in the thread I referred to above (apologies dont know how to link to it). It seems lag is not an issue when using the HD80E to just pass through the signal. There is lag when users have tried to record the signal (which clearly I wouldn't be trying to do).

I know the cost will be an issue, but it seems like an interesting setup to try for.

 

With that setup, you're looking at a cost of $400 plus the GPU, just to be able to play games using the notebook display. If you're on a budget, you're much better off buying a powerful gpu with which you can afford to get a 20% performance hit yet still achieve excellent frame rates for a notebook pc. When your main goal is to have a portable setup, instead of a fixed gaming station (hooked up to lcd tv etc.), an expresscard solution is less complicated, cheaper and with the right gpu, it will be equally fast. The $250 that you save, makes the difference between a 2gb gtx 660 and a 4gb gtx 680.

 

I still don't get what's this for
