because "Gaming Computer" (ex: prebuilt packages) are for suckers. Slap the word "Gaming" on a standard optical mouse and it'll sell for 2x$.Yeah why can't they sell a gaming computer as cheap as some of these consoles. Or realistically, maybe a couple hundred dollars more.
I built a pc a year ago using mostly components that were available 2 years prior and earlier. From that state the only upgrade (or component <6mo old) was a GPU.
Theoretically, my 3yo pc was upgraded at less than half the cost of any new console. I performs well enough to run UT3 @ max in 1680x1050 while recoding fraps @ 30-40fps ave.
The market is $$ driven. Until a majority of it's supporters (consumers) gain the lego-level knowledge it takes to assemble PCs and the desire to spend 10min doing so, prebuilt systems, console and "Gaming PCs" will continue to sell as long as there's someone to throw money at them.
