Superfast PC configuration [closed]

I have a very specific program that I need to have running as fast as possible. I wish to buy a super-fast PC in order to run it. The program is already written to make use of multiple cores and on an N-core machine it will run very nearly N times faster. The program spends almost all of its time performing integer operations with no disk access and very little IO so I don't care about graphics or hard disk performance at all.

"Server product lines offer six-core cpus. If you're budget limited, though, you will get a lot more bang for your buck by moving to Linux -- that will allow use of all available cores, memory, etc. The porting effort is probably less than the licensing of the high-end Windows version you'd need.

I'm assuming, since you're very performance oriented, that you're already using a fully compiled language (not .NET, for example), at least for the performance critical portions of your application."

For $2500 you can buy 8 PS3s. Link them all together with ethernet and set up one of them to be the "leader" that gives out workloads. You'll have a much faster setup than something that would be in a $2500 PC. Each PS3 has 8 SPE's (Processors) and one PPE (Power Processor Element) that acts as a controller for the 8 SPE's. You can realistically only use 7 SPE's as the system steals one from you. So 8 PS3's times 7 Processors is 56 Cores. Considering you said your code scales N-Core that is 7 Times faster than two 4 core processors on a single motherboard.
