Let's cut it down to http://www.google.com/search?hl=en&source=hp&q=core+i7+versus+xeon
And cut it down again to "find benchmarks" then compare. The problem is that it is doubtful that a great answer will emerge except you will pay dearly for the XEON solution (ECC RAM and more!)
If computation is the goal, did you research possibly tapping into CUDA?
I want to buy a computer to use as desktop to run very heavy computational jobs. I want to work in both Linux unbutu and windows 7. I am going to use LAMMPS software in Linux environment which is capable of using as much as available core. Two different configs were recommended
1- Core i7950 and ASUS P6T
2- 2*Xeon 6530 (two 6530 processors) and super micro X8 DTLi
I know that prices are highly different but I have following questions
* Is xeon cpu capable of being used as desktop and is compatible with windows 7 and linux
* which one of the above configurations would work faster (for my usage)
any help, highly appreciated.
