A few quick questions on a prospective rig

Okay, well I'll preface by saying that I've never used DigitalStorm before, but I've also never made such a high dollar PC purchase before, and from everything I've read/researched, these guys are pretty much the acme of the industry, so thank you to DS for knowing that quality and customer service are paramount to staying in business.

Moving along, I currently run at a resolution of 1650x1080 (16:10), but I may plan to migrate to 1920x1080 at some point down the road, and do sometimes hook my PC up to my TV for viewing on a larger screen (99% of the time this is movies, the other 1% is when I'm gaming and can't get out to get a new monitor when mine busts.)

So here are my questions, with the rig specs to follow:

1. Will a 1000w PSU be sufficient to provide the juice to this rig and keep it stable assuming I take the free CPU overclock and no other tweaking to voltages, and...
2. If it is, would it be able to push two of the GPUs (gtx480) in SLi should I decide to double up somewhere down the road?... and if not...
3. What would you guys recommend as far as PSU output to keep SLi cards as a possibility?

As a footnote, I note that the PSU does say it's dual/triple/quad compatible, but I also know that the gtx480 draws a /lot/ of juice, and the 980x won't be a slouch either when OC'd.

Thanks to anyone who can offer any insight!

Thanks for the reply :D

980x will definitely benefit gaming while livestreaming the game, and I also do a lot of photoshop work and a bit of 3d rendering on the side.

As far as premium price RAM, I always believe you get what you pay for with RAM, but maybe I'll have to take into account that DS doesn't use bargain bin RAM as their generic choice. As far as ASUS, I love them :P Call me a fanboy, but every MoBo I use is an ASUS and I've never had a problem that I didn't cause with them.

and back to the main point, the 1000w won't run even 1? Or are you saying it wouldn't be able to handle SLi down the line? Because I'm still on the fence as to whether or not I'll even bother with SLi proofing when the solo 480 will be able to handle almost anything I throw at it at this point.

the 750W TX would run u 1 gtx 480, 1250W is just for if you want to go sli 480's in the future. The 980X rly seems like an overkill though cause are you OCing it yourself? if your not even going to OC it yourself and u take the stage 1 OC from DS then its rly just a big waste. 

Thanks for the input so far guys, though I'm not asking anyone to reconfig anything, if you're having fun, by all means, I enjoy seeing others' takes on things, though I am pretty cemented in my decisions (sans RAM, which I am now rethinking, thanks to Dragoon's insight into DS' RAM quality) so don't take it as an offense if I reject a change.

And thank you for the responses on my PSU issue, which is really what I am clueless on. Glad to know I can step down a notch to a 750w, and still be fine. I figure I probably won't be going SLi in the near future, but even if I do, getting a PSU and chucking it in is easier than making a grilled cheese.

Plus if anything, I figure that if I do upgrade my GPU, I'll move to the 490 when it comes out, and since that's basically the 4xx series answer to the 295, I should be golden (aside from the rig being a veritable fireball of heat)

Also, for ablahblah, the budget I've figured out for myself is about 4600$~ after CA tax and shipping (this leaves me enough room for liquid cooling further down the list of specs).

And @Mr. : It is a bit overkill just for gaming, but as I stated earlier, I do a lot of Photoshopping with very large canvases, as well as some side work with 3d rendering, where the 980x will really benefit me when I want it to, but I appreciate the words of warning on 'going too far' :P.

Again guys, thanks for the correspondence, I definitely appreciate the answers to the PSU question, now I'm a bit more at ease, and I think I'll just drop to a 750w since I don't need the 1000 now or later.
