Sorry Linuxs version of Aero doesn't require a 1GB Ram requirement, darn them FOSS heads for optimizing compositing and all them other features in less than 1-10MB.
Other than that, most Windows system really won't saturate most of the high end equipment you put into a computer anyways. Unless you're doing extremely specific stuff, such as rendering, compiling, folding, etc. Which Linux ( in most cases, until you get even more specific and add .NET and Windows only programs ofc ) can do just as easily. And aside from those things, there's not much to really stress a system and put it to the use they're made for, gaming can add a little but alone by itself isn't enough to really use a system to it's full potential. No system will.
Most people here with $1000++++++++++ machines, are going to fall under the above about the truck. It's more "bling" or "bragging rights" than anything else in most cases.
Not sure if serious. I guess my Linux HTPC box just has good luck then.
