I tried playing around with one core, my system didnt like it. I think if you are benching at 4.6 your not doing so bad. Never actually ran any tests but I have to assume that 8 threads would be better than 2, or even 1. If you can keep your temps down and run at 4.8 or above with one core then you might want to try. Like I said one core gave me no free ghz. Hey just watch your temps and see for yourself. Im not running a classy maybe it will be easier for you. Make sure to submit cpuiz score if you boot with one core real high.
