Progress: "a movement toward a goal or to a further or higher stage" (dictionary.com)
If you're continually spending thousands on the latest PC parts that will be worth a piece of cardboard in 2-3 years, where's the progress in that? Ask yourself honestly whether you are spending money on anything other than making games look prettier. A brief satisfaction at best. There is no goal, other than continuously bleeding dry the pockets of graphics junkies. I can hardly talk, I like high-end graphics too, and I probably will get a directx10 compatible card at some point (as long as there's none of that DRM crap on it, but that's another topic, so please lets not get started on that, I agree this topic is overstretched already). However, it is helpful to recognize the nature of the computer hardware market for what it is, an ongoing attempt to create a demand for expensive stuff that no-one needs. That doesn't mean that every new product is a rip-off, but a bit of perspective on whether that new game is worth a thousand-dollar upgrade is a good idea.
Peace and happiness to you all, especially anyone who doesn't like what I'm saying.
