Video card upgrade to SLI, can my PS handle the load?

PS: OCZ 700 watt PSU. There are 2 pci-e power plugs, so it could support 2 cards.
Vid Card: EVGA 8800 GTS 640 (takes 1 pci-e plug)
Board: EVGA 680i sli
CPU: E6750 @ 3.2Ghz

I know the PS can handle 2 of these 8800gts' with no problem on this board, but what I don't know is if there is enough juice in the PS to handle the rest of the setup:
4-disk SATA RAID0
2-disk SATA RAID1
controller card w/ SATA dvd burner
x-fi gamer sound
gigabit nic

I need a video card upgrade, and have found locally another 8800gts 640 of the exact same make and model of my card for $50 so I could go the SLI route to put off the major upgrade for a while longer.

Will 700 watts be able to power all this, or is the whole 8800gts 640 in SLI route futile with the 465 fermi cards being <$250?

Yes. HDD's hardly consume much power to begin with with 6 HDD's would only take up something around 50W on load.

In fact your PSU is way too overkill for the setup.

Since it will hold the power, the next question is:
Is it worth the $50 to get the extra card and attempt SLI, or just take the plunge for a new card altogether? I haven't found any benchmarks that show the 8800 gts sli v/s the current generation.

You can a GTX460 1 GB and overclock you proccy a little.

I wont hurt to have the 8800GT SLI running till you can upgrade your complete config.

You can sell the video card and get a new one that will be used in the future rig too. You can wait a little bit, the prices are dropping.

To defend its market share, AMD plans to cut prices for its ATI Radeon HD 5000-series GPUs in the near future. The action also serves as preparation for the upcoming Southern Islands GPUs, the sources noted.
