Power supply recommendation needed for Core 2 Duo and 8800GTX

[DanG]

It's new system time and I'm going big on this one.
Core 2 E6600, 2GB OCZ Platinum ram, Asus P5B and either the eVGA or BFG 8800GTX video card. I'm keeping my existing 36gb raptor, my 300gb seagate sata and my nec 3520 dvd burner. I'll be using the onboard nic and sound.
eVGA recommends a minimum of 450w psu with 28amps on the 12 volt rail, and BFG wants a 450w psu with 30 amps on the 12 volt.

I'm stuck on power supply.
So far I've looked at:

OCZ GameXStream 600W (4x12 volt rails @ 18a each)
Thermaltake Toughpower 600W (4x12 volt rails @ 18a each)
Zalman ZM600-HP 600W (4x12 volt rails @16a each)

They're all fairly close in price, and all seem to provide enough power.

Which one?

OCZ for the warranties.

I second the OCZ of the three you have listed.

[DanG]

They have a bundle deal, I can get the OZC gamestream 700w for $10 more.
Honestly, the only upgrade I see myself doing in the future on this system will be going to a quad core CPU.
I'm pretty sure the 700w should be a no brainer upgrade. Am I right?

My next power supply

Enermax Galaxy 1000W EGA1000EWL ATX2.2 Modular PSU

Outstanding in every area - but you pay for it!

I just ordered the Corsair HX620 today from ZZF. It's not cheap but from the reviews I've read, including JonnyGuru's review, they are high quality psu's and use very high quality caps inside. Plus, it's modular and it has a 5 year warantee too.

OCZ all the way. I am very happy with the one I have.

How are all the 12v rails used? Is 18amps tops when looking at multiple 12v rails?
