Talking Need Opinion on PSU


I have been looking to build my first PC rather then buy a pre-built. I know what I want for most of the parts except the power supply. I am looking for a PSU for the following build with initially an Visiontek 4870X2 but might add a 2nd in CF later. I know the Cosair TX-750 is good for 1 card, not sure for two.
Any other comments on build will help too. For gaming mainly and trying to future proof it for at least 5 years.
Pricing not worried about.

Q9550 @ 2.83GHz (would like to overclock, maybe to 3.8 or 4GHz)
Asus Rampage Extreme
4GB OCZ (OCZ3RPR16004GK) DDR3 PC3-12800 1600 MHz Reaper HPC Edition 4GB (2x2048MB) Dual Channel
(Maybe add another set of 2x2GB later)
Vid Card:
4870X2 VisonTek (Might add a 2nd one later)
PSU: Corsair tx-750
(ATI CrossFireX™ | GAME.AMD.COM listed as one for CF 4870X2's, but thinking of going for a 1000W PSU)
Hard Drives:
Western Digital Caviar Black 640GB 7200RPM
OCZ Vendetta 2(Most choosen cooler on this site)
with Thermalright LGA775 BOLT-THRU Kit
Coolmaster HAF932
Optical Drives:
ASUS BC-1205PT Blu Ray BD-ROM Drive & DVD Writer DVD+RW 12X8X12 DVD-RW
Lite-ON IHAS220-08 SuperAllwrite SATA 20x DVD Burner with Lightscribe

Vista Home Premium 64-bit (Is Ultimate even Worth it?)
BenQ FP241VW 24" Monitor ( Wanted to upgrade from my 19", plus get 1920X1200 Res)

Don't think I am missing anything.
Have fun commenting.

Oh man. If you wanna Crossfire two of those suckers, I would HIGHLY RECOMMEND a 1000W PSU. If you're not going to, then just get the TX750...

Firstly, welcome to HWC!

Secondly, future-proofing for five years? Good luck. Within a few years, you'll probably be groaning about how your once-top hardware can only manage medium settings on the latest games. Just the nature of the game, unfortunately.

Don't bother with Vista Ultimate unless you know for certain that it has a feature that you need. Home Premium covers pretty much everything the average user will ever need, for much less money.

The TX750 will run a pair of 4870X2's, but perhaps not with as much headroom as many people (myself included) would like. The Corsair HX1000 is a nice upgrade, reasonably priced for a 1KW PSU, has modular cables, and pretty much guarantees you can run any hardware you want. With a little patience, it can often be found on sale for a few bucks off, too.

Think real hard before going for the second 4870X2, as the returns are very diminishing for the money and power needed, especially on anything less than a 30" monitor at 25x16. And that's assuming a given game is even able to begin taking advantage of the second card.

Thanks MpG!

Thought that would be the reply for the future proofing. If I am lucky maybe 2 or 3 years and then games will be laughing at my unit again.

Vista premium 64-bit it is then still on the fence about the 1000W PSU. Don't think I will get a 2nd 4870X2 yet till either games need it or till they drop in price because of something new out.

Keep the comments coming
