Its not for a certain use to be honest, Like i said i work 7 days a week and i love my tech and have seen the sr-x at a gadget show before, i love the look of the sr-x board too (i know many dont because of the position of the ram slots)
Use wise, i do a lot of gaming, a lot of video editing (for work) and music production, And recently ive got into game creation and animation for the games so it does take a lot of power. the i7 might well handle it i was more just general info about them.
I dont use a lot of stuff which would need a workstation as such but my love for tech just takes me to the higher specs on everything.
I know there a lot of dreamers out there but its annoying when the genuine get tainted with the same brush ....
