Depends what power supply you're talking about. In general you can't say "that much Watt you need" because important are the ampere specifications, esspecially for the 12V line. And even it would work stable, the supply would work on it's borders. And this would result in much less life time.
Trust me, a good 500W (or more) power supply (e.g. from Tagan, Enermax, Corsair...) will help you in your future computer plans. So you won't need to replace it in your new computer.

No one talks about overclokcing. It's just better and that board costs like 20 bucks more, so there is no reason to get the worser one.
X48 chipset is fast, supports every socket 775 CPU and has Crossfire support. The SLI chipset from Nvidia gets too hot and is sometimes not stable with different RAMs.
I really recommend you a X48 or X38 chipset from Intel, since I made really good experience with it. I got much better feedback than e.g. the 650 SLI chipset.
And about the GFX card: The HD 4850 is way faster than the 8800GT, esspecially in high resolutions and high quality settings. And sometime, when it's getting too slow you buy e.g. a next generation Radeon (doesn't need to be a 4850) and you will be able to use Hybrid-Crossfire to push up your graphics performance.
