i personally like AMD but when it comes to performance AMD doesn't compare to intel, while they cost more per cpu their cpu's have a better refined cpu manufacturing process taking them down to less than 45nm. they have hyperthreading which allows them to have up to 12 threads on a 6 core processor and 8 on a quad core, hyperthreading increases performance in a lot of tasks over AMD.
i just can't wait until AMD comes up with a processor that can match intel's core i7 series in performance in all aspects. Currently AMD doesn't have any comparable chipset, at a lower mhz than the 1090t the core i5 760 almost scores as high in the processor arithmetic test within Sandra.
