Getting new PSU for 9800gx2, need opinion

[rsasp]

I got a 9800gx2 recently and unfortunately my current PSU is 550w( Antec True Power Trio TP3-550), and I feel is not strong enough, so I have decided to get a new PSU.
I have my eyes on these three PSU:
Antec TruePower Quattro 850W PSU TPQ-850
CORSAIR CMPSU-750TX
OCZ GameXStream OCZ1010GXSSLI

not sure which one would be the best, price and performance ratio.

my setup:
AMD Athlon 64 X2 6400 Black Edition
ASUS CROSSHAIR Mobo
EVGA 9800GX2
CORSAIR XMS2 4GB PC2 6400
2x Seagate Barracuda 7200.11 750GB
2x DVD/RW

Corsair is my choice. OCZ are known for the bad ripple under heavy loads which can contribute to an unstable system. I also seam to recall some issues with the new Quatros from Antec. Something to do with compatibility issues with some motherboards. Though I'm sure those have been long since resolved.

antec compatibility issues with some motherboards? what do you mean?

get a PC Power & Cooling, those have a reputation for being rock solid. I have a PC P&C Silencer 750 Quad.

isn't PCP&C part of OCZ now?
and PCP&C is mad expensive at where I live.

the PC Power and Cooling Silencer 750 is very much like the Corsair TX650. Both made by Seasonic. Corsair TX650 is rated at 50C and PC P&C is rated at 40C so basically if the Corsair were rated at 40C like the PC P&C, it would be rated 750 Watts. Newegg is terrible about updating their Specs, but notice they list the OCZ as only having 6pin PCI-E connectors, the 9800GX2 needs an 8 pin and a 6 pin

Edit:just looked at OCZ's site..it only has 6 pin connectors. But there is also the question of whether or not you may get a 9800GX2 that won't work well with a 6+2pin type connector, but the TX750 and TX650 have 6+2 pin connectors at least that can use an adaptor to straight 8 pin.

The best power supplies I have ever owned were Corsair. Never had any problems.
