I am trying to build a 64 bit RHEL Server. I use my system only for running lot of VMImages and analytics softwares. I am not into games. Trying to build a 64 bit system basically for large memory access to rum both 64 bit and 32 bit VM Images. My choices as far as CPU in concerned are between i7 870, i7 950 and AMD Phenom X4 945. And for the mother board Gigabyte X58AUD 3R and MSI 890GXM G65. The price difference between the Intel option and the AMD option is almost $400. Any comments. Which would be a better option.
The Hyper-Threading on the I7 CPUs will not benefit you as much a physical core. For hosting VM you want physical cores. If you can't consider a Phenom X6, then I would agree that the four cores on the I7 950 would be the way to go.
