Kabouter as a pc guy yourself I see a lot of people saying PC hardware has changed, what am i missing here?
Your point about the dwindling desktop sales is something i havent even thought about in this regard.
Im curious if F2P will make a transition from ios/pc to consoles.
Well what has changed is that PC GPUs, generally still the main determinant of performance, consume far more power and take up far more space than GPUs did around 2004-2005. Graphics cards these days are massive hungry beasts. It seems unlikely they'll make sufficient efficiency gains at reasonable cost for the new consoles to have GPUs that achieve the power the 360 GPU had compared to PC contemporaries. For reference, the 7800GTX you mention had a TDP of 81W, a current high-end GTX 680 has a TDP of 195W, a high-end AMD 7970 has a TDP of 250W. Neither is a dual-GPU card it should be noted.
For CPUs things haven't changed too much, if anything power consumption has gone down there, so they should be able to push considerably more there, and I fully expect them to.
And F2P will definitely make that transition, bet on Sony and Microsoft accommodating F2P as best they can. They aren't going to ignore the money being made there.
