Hello guys, I am looking to upgrade the CPU on my Dell Precision Workstation 490. It is currently running 2 Intel(R) Xeon(TM) CPU 3.00GHz. My Bios is running firmware A03. I am not sure what is the fastest processor I can get for this WS. I was looking at the Intel Xeon x5365 3ghz quad-core. Is there anything faster than this that is compatible with this system? Thanks
