Quote - ATI Radeon HD 5970...the way to go !!!

Don't invest in any ATI Radeon graphic cards if you want to use all newest improvements in VUE 8 / 8.5.
 
These newest versions of VUE is optimised for all new NVIDIA cards with CUDA technology.

Any ATI cards have not CUDA !   

The best choice for VUE is:

cheapest card =  NVIDIA GeForce 9600 GT

medium priced = NVIDIA GeForce 9800 GT

high priced =  NVIDIA GeForce 250 GTS

Any ATI Radeon is NOT PREFERED for newest Vue !

Good shoping !  :)
