I'd like to point out the fact that most likely everyone on this site has a PC and most probably have one that's not ancient. In such case, upgrade cost is what counts. And then there's the fact that occassionally people will have to get new PCs anyway, in which cases the cost of gaming should be the extra you have to pay to get a gaming-capable PC compared to a basic PC. For example, a basic PC costs $500 and a gaming PC costs $700. There's a $200 difference so you just paid $200 for the gaming part of your PC. Of course this isn't the whole truth as the frequency of upgrades might vary, but... Well, I think it points out pretty well that you can't just take the price of a whole new gaming PC and say that's the price of PC gaming.
