Geforce 7600GT or 8400GS in Diskless MD?

[Thingie]

Hello,

I want to set up a MediaDirector and connect a diskless MD to it. I have a GeForce 7600GT and a Geforce 8400GS. The 8400GS has a special processor that will do all the HD calculations and so offload the CPU greatly. I will use the Diskless MD to watch movies and tv. Now I'm not sure which card to use in the MediaDirector? Does the MediaDirector do all the work and does it not matter which VGA card is in the Diskless MD or is it the other way around?

By "Media Director" you probably mean Core or Hybrid. 

Anyway I doubt it will make much difference which card you pick apart from that I would expect the 8400 to use more power and thus generate more heat.

Yep I ment the Core. Ok, if it doesn't matter I will use the passive cooled 8400GS in the Diskless MD.
Thx
