yewlregarding the 4770k; you wont get any different fps with the i7 (hyperthreading) in tf2 - in fact i cant see hyperthreading benefiting you in any games currently
what it does it essentially add 4 'virtual' cores to the 4 physical cpu cores of the 4670k - but no games at the moment can utilize more than 4, rendering the virtual cores useless for gaming
I see thanks for the response
