What xenon for 80 channels

I would like to buy octa cards for 8 transponders and xenon server.
My question: what minimum xenon processor i need for about 80 channels + descrambling by oscam all 80 channels. I don't want transcoding.
example :
2 x Intel Core Xeon X5550 @ 2.67GHz Quad Core Processor's
24GB Ram
