It's been a few years since I could afford any new components for the PC, you really need to be a dedicated (and well off) gamer to keep up with the constant improvements required to run the latest games.
That *could* be game developers pushing new technologies to the extreme, or chip/software developers rushing headlong to be the 'first' in the market.
Whichever or whatever it is, I'm sure money is singing in the background while the more destitute among us turn to playstations and dump the PC in the bin
