i'm coming up with a new tool for PSU choosing.

in the mean time - this thread looks good so far.
about the future proof thing - it's nonsense!
buy a 700w PSU today, and 2 years down the road the max output would've dropped. future proof what?
and buy 500w PSu today would it mean it won't be supporting stuff next year? not really, if you look at computers, manufacturers always aim to lower the power requirements as the fabrication processors goes smaller and smaller. don't believe? see for yourself

pentium 4 / pentium D has higher TDP than what we have now, the Core series. only the higher range have higher TDP ............
but here's the interesting part (and I'm might use this on my upcoming article) - if you're always using it on low-medium range, your PSU is likely to last the next few generation of medium range. and when you can suddenly afford a high range, you can also afford the PSU for it.

so yeah, if you can afford higher range processor, so can you afford higher range PSU too.
seriously, there's no way you could suddenly afford a GTX295 / Core i7 and not afford to get a PSU for it. it just doesn't make sense.
graphic cards?
