CPU utilisation with Soft CAM/oscam descramble

[pekovi1]

Hi All!

Do we have any forum member here who can share his experience with soft CAM descrambling?
I am considering to use quad or octa DVB-S2 PCIe receivers and descramble the TV channels via o s c a m, but I have no idea if it would work with about 40 TV channels. 20 SD and 20 HD. Can someone share with me what is the CPU utilisation with SOFT CAM decryption?

If it can work what x86 CPU would you recommend to use? If I would like to try also video transcoding for several HD channels to transcode it to lower bitrate does also GPU have any influence on the performance?
Any help is much appreciated.
Thank you.
