I'm getting ready to buy a new system - I haven't been keeping up with the latest benchmarks, as far as CPU's and motherboards go. To give a little reference the last system (x86) I bought, was a 1.4ghz AMD Thunderbird, and now it's time to upgrade. As far as setting some parameters, Dual CPUS is no concern (at least not for this system), and somewhere around $600 for the motherboard and CPU. I'd prefer to stick with AMD, perhaps one with one of the Barton cores, but I have no idea on a motherboard. Have Opterons gained any ground? Edit: Minor corrections.
