What are the minimum scores you recommend?
Are you talking about videocard, right? Then you may choose any AMD card >=5670 OR NV >=9600GT and there's no need to test it with SVPMark.
I don't understand why CoreAVC is listed with Madvr and SVP
On my AMD X6 software decoder can take up to 15-20% of CPU (it's like loosing one core from six). So with hardware decoder (like CoreAVC or HAM) I can get another "core" for SVP calculations for free
