Need mobo/PSU/RAM recommendations for 8800 GTS SLi

[Gantic]

I have 2x8800 GTS 640MB and i've previously been running them un-SLi'd. My CPU is a Intel E6600 2.4 GHz.

I'm looking to buy a new PSU/mobo/RAM to run a Windows 7 PC with performance geared at gaming. Any recommendations would be greatly appreciated since I don't have to first clue what to look for when shopping for a motherboard.

I will be running 3 hard drives and a DVD drive.

Thanks

You can't go wrong with the Corsair or the Seasonics on the cert list.

With that said, there is only ONE MOTHERBOARD I'm comfortable with for an Intel processor that's SLI-capable and that's the Asus P6T Deluxe V2, and that will require you buy an i7 processor. The only boards that are compatible with your E6600 have Nvidia chipsets, which are not particularly stable.

If i'm going for a new CPU, would you recommend Intel over AMD? Will say a "Intel i7 920, D0 SLEBJ S1366, Bloomfield, 2.66 GHz, QPI 4.8GT/s, 8MB Cache, 20x Ratio, 130W, OEM" be considerably better than my existing CPU? Will SLi be considerably better than individually? Is the cost worth it?

Should clarify, not really looking to drop a ton of $$$ but would be willing if I can be convinced, lol. How are the i5s? What sort of i7 would be reasonable?

I'd keep the board and CPU you presently have, sell the 8800's and replace them with one strong card such as an ATI 4890. Max the ram out in your board.

Either my motherboard or my PSU has died (probably my PSU) but none the less I think i'm in the mood for replacing both. If I settle on the following components, is there specific RAM brand/speed/size you recommend?

750W TX Corsair PSU, single 12V rail, quiet & cool 80%+ Eff

Intel i7 920, D0 SLBEJ S1366, Bloomfield, 2.66 GHz, QPI 4.8GT/s, 8MB Cache, 20x Ratio, 130W, Retail

Asus P6TD Deluxe, Intel X58, Sok 1366, PCI-E 2.0(x16), DDR3 2000/1800/1666, SATA 3Gb/s RAID, ATX

The site i'm buying from said this motherboard is phasing out the one you mentioned, would you go for this one or the old one (they're almost identical in price).

Thanks for all your help so far.

Also will 750W be enough to power 3 HDDs as well as the SLi setup/i7?

I'd stick with the older mobo because it's known stable. The X58 chipset hasn't been one of Intel's more stable efforts in general. If Khalil pokes his head in maybe he can tell you which ram has worked best for him in that board, I know he's built several. 750 is plenty, the certifications assume a well loaded system.

I don't like the X58 chipset, I have yet to build one machine with that chipset without going through all kinds of issues. This is why Intel scrapped it. I am building some P55 machines, the first batch of motherboards that came in had sound issues, the replacements are working flawless but not with 64 bit.
If you insist on going with an X58 chipset, Kingston KVR1066D3N7K2 is the only memory that we had good luck with on that chipset.
