This is probably true on the hardware side, and definitely in the performance vs. price ratio in my experience. But in terms of software, no way, all the crap that is installed on PC's nowadays (to keep cost of hardware down presumably) is crazy. First thing
I do when I get a machine from an OEM is wipe it, much much faster without all the stuff they install.
Oh dear god yes, OEM Windows installs are often a complete mess of useless junk. I was referring purely to the choice of hardware inside.
