In addition, I believe you would require 4 copies of Excel.... and possible 4 copies of MATLAB.

I am not factoring the licensing fees....I wonder The Windows Server 2008 R2 Enterprise can use its own vms or through any vm softwrae like vmware?

If you're not factoring in licensing fees... then how did you come up with the $1500 budget? That doesn't make sense.... The Total Cost of Ownership must include it software costs.

the 1500$ is for hardware only....the software might be rented or leased for a certain time before I get enough paid subscribers.....

speaking of renting or leasing... you may want to look into getting a dedicated server to rent. You could even rent a large windows virtual private server. That way it is virtualized by a company that can handle hardware faults. Licensing would be the same as it would with your own machine. In this case one large virtual machine would work well and could have all the resources you need to run multiple instances of your software.

it is pricey, but with an extra large instance and a 1yr commitment you would pay about $340 per month. I think this is a good deal considering that you get to use amazon's super fast network and reliable storage. You can get good deals other places, but amazon really is awesome. This way you can scale up or down easily based on your customer demand. scaling down when you have spent more than you need on hardware is always painful.

Right now I have it setup with Win8 folding on half the cores, and running four VMs off the other 8 threads.
The best part about the CPU is that it runs so cool, under 42C w/ a h50, and sips power.

So far in my experiences, I've been continually disappointed every time I put a massively multi core machine with slower clock cycles against a blazing fast, smaller chip.

 

I would gladly trade an 8C, 2.4GHz Xeon for a 4C, 4.8GHz i7 any time assuming both are stable.

 

My biggest disappointment so far has been with my 4P Opteron 48C machine. It's constantly being out performed by 3930's in wide ranges of tasks.

thank you for your suggestion...I have looked into these and am still very curious...I am just not sure how these servers work - do I upload all of my software there? - do I need to upload my proprietory model files there???? I do nto trust any remote server to handle my model files no matter what kind of the guarantee they provide...can oyu please help me understand how an instance could be used to auotmated recalculating large excel files 1000 times in sequence? well actually many more times...

sounds very interesting......yes I am also thinking a multicore cpu with enough horse power is needed - even if it has lower cores - the XEON E3 1275 V2 looks great in this regard - even if compared to i7 3930k....what do you think?

I wonder if you have tried running your i73930k for long periods of time..like 10 hours or 24 hours at the maximum load....I wonder how it behaved? lets say for 8-10 hours in a row....at 95% (no over-clocking) - did you see any hints of instability in its performance?
Thanks!

why not look into a dual 1366 xeon set up if u purchase standard 4 core xeons you'll have 8 cores and 16 threads with decient speeds you could probably find the six core variants for fairly cheap since its older. the whole system could be assembled for less than $1500 and would provide massive processing power. not to mention all the perks of the xeons

I know people fold on these setups with 100% processor load for long periods of time

You can't rent software?

Yeah, cloud computing might be another way to go.... http://aws.amazon.com/ec2/pricing/
