Thanks for the prompt and detailed answers Lief and Alberto ... My 3800+ Athlon is also a single core but two months ago one of my memory sticks shorted and took out my Motherboard and I couldn't find an exact replacement ... but did find a Asus A8N32-SLI (939 pin) and it said it will also accept a dual core CPU ... needing an excuse to buy a dual core CPU, my thoughts turned to SDR and writing a program that can handle TWO or more separate IQ streams from a 4 or more channel sound card (or 2 cards) and summing them together ... if each stream has its unique digitizing noise, a potential 6 db of noise floor improvement could be had ... and with SDR front ends so inexpensive, this dual channel could be extended to the antenna ... just a thought ... anyway thanks to both Alberto and Lief for your efforts to produce the best SDR software on the planet ...
