I was in need of quality AMD Opteron and Intel Xeon based high performance Rackmount servers at a good price so I searched around on the Search Engines. And atlast I found High performance computing Systems at http://www.hpcsystems.com/, which is AMD platinum partner providing high density 1U quad to 5U 8-socket Rackmount servers providing up to 32 cores with 256GB of memory capacity.I hope this would be helpful for people who are in need of quality servers.
