thats the one josh! i think its far better value than your dell options, but at the end of the day its your decision. What it all balls down to is what you use your computer for, if you use it for light office/student work you may as well save a few hundred pounds/dollars (for my American friends)
and get a lower spec machine and spend the rest on chocolate, beer and one of those cool chairs that have heaters and vibrate.....anyway
i know how much of a pain in the backside buying and getting the right machine is, so best of luck and i hope i can help as much as i can.
Also anyone is welcome to get me one of those chairs for Christmas, there only £200!
