I've been doing some further reading on the subject and I think my original post is incorrect. The statement about 99% being written to run on one processor is the most confusing, because it fails to allow for HyperThreaded single core processors. I am not a programmer, and have waded out past the shallow end. It should be very easy to test the efficiency with which PowerSDK deploys 2 cores over a single core. Benchmark a system running a single core processor with PowerSDK running along with several other programs that the original poster mentioned that he would like to keep running, then using a tool like Sysinternal's "Process Explorer", look to see how balanced the split CPU load percentages stay when PowerSDK is fired up (while the several other program are already going). I hope this makes sense.

And four cores working simultaneously would certainly run circles around it? Well no, only if the application that you are running is multithreaded and thus can take advantage of the extra cores - remember that about 99% of all software available today is programmed to run on a single core processor. Hence it isn't multithreaded and thus in the vast majority of cases you won't see a speed up, as the second, third or fourth core is just sitting there idling, or handling simple operating system tasks that don't eat up a lot of processing power in the first place.

Time to change the CPU and Mother Board. I have both a SRD 1000 and 5000. I run a lot of stuff in the background for biz (CS4-Dreamweaver, etc) and use 4 monitors. I have been eyeing the 6600 CPU's for $189.00 from Tiger Direct. I would love to hear from others if this is the way to go and a suggestion of a good Mother Board to go with it. Also, what is the SDR software designed or best suited for - Duel - Quad, etc? -- _______________________________________________ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kb.flex-radio.com/ Homepage: http://www.flex-radio.com/ _______________________________________________ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kb.flex-radio.com/ Homepage: http://www.flex-radio.com/ -- "Sapristi nabolis!" -- Count Jim Moriarty _______________________________________________ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kb.flex-radio.com/ Homepage: http://www.flex-radio.com/
