Haha, just stick with the MX518 bud ! Just save yourself some pennies - I'm still using mine now.
Out of interest, what's your current spec? Seeming your interested in the new SB..
.None, sold my rig last year when I moved to Canada.
Im back now and need a pc for uni, but tbh, I'm still thinking about SB, I don't game (maybe once or twice a week if im lucky) and I don't do video encoding. I think a BE555 and Gigabyte 880 ud2h for £120 would probably suffice.
Gonna wait until tomorow and see if any SB laptops come out thou cuz that's what I ideally would like to get.
Ah right, so you ideally want a laptop then - you're not after building a comp?

What parts do you need? Everything, i.e. case (all internals), monitor, speakers, keyboard, mouse, etc or ..?
