Yep, I guess I agree about rhe PSU then. 800 Watt is quite a lot. Still... You know, when I build machines, the PSU is the first thing goes into the enclosure, and usually either the last thing to come out, or the only thing that remains. So I just figure, it might be good to have that one component as future-proof as a PC component can get. But yeah, you are right; 800 Watt seems overkill.
About graphics card: oh no, no, I think you misunderstood me. When I say get a high end graphics card, its because those cards usually remain high end for years to come. When I buy a graphics card, I usually think ahead three-four years. I think in contingency, that I might try different setups and games without having to upgrade my hardware for a while, and I would personally rather go with a card that's way too powerful, rather than one that's just powerful enough. That's me though, and I'm probably kinda crazy. :-P
The thing is, if you get a Radeon 7950 or Geforce 670, those cards will be able to run every game that is out now, and most games to come for at least the next couple of years (or three) with most setting on high, very high and ultra, and have extra bandwidth in case you upgrade your monitor to one with higher native resolution, or get a multi-monitor surround setup.
There's also the fact that game developers are gearing for the next gen now. I read recently that Epic uses a Core i7 with a Geforce 680 as their primary development platform for Unreal Engine 4, so that seems to be their guess at where the next gen is going to be. I think if a guy is interested in playing both present and future AAA titles, and have them looking and playing as good as can be, then now might be a bad time to compromise on the graphics front.
It depends on what mozzington wants though - bang for buck, or premium experience. If it's the latter (and it looks that way from the components in his setups, and that he says price is no object), then I think he should go for the most current gen cards. If it's the former, then the Geforce 560ti is indeed a mighty fine card that will serve him well. :-)
