If you're going for SLI, just buy the largest PSU you can get. I went from 750w to 1000w, even though I only use a single mid-range card. You're not wasting money or energy as long as it's a 80+ gold rating. The stuff that comes in HP's and Dell's are extremely cheap and usually noisy underpowered things that die if you try to put any video card or cpu more powerful in it than what came with.

And it is the GTX, i don't even think the use GT past the 630, but i may be wrong. You always want to look for the GTX. (for the most part)
It's a known fact that Video Card manufactures have been purposely putting more ram on cheaper parts because RAM is currently cheap AND people don't pay attention. On the CPU side, more RAM is always better, but beyond a certain point you don't get greatly diminished returns. On the GPU side, different values of parts have 1/4 or 1/2 the memory bus as their top tier model, so a cheap part with 4GB and an expensive part with 4GB, the cheap part will still be 25% as slow just due to the bandwidth bottleneck.

What you'll usually see is that nVidia and AMD have several price points, of which the top part is usually 600$, and a PSU will not have adequete power to run two of them. My configuration with the PSU calculator says 400w is sufficient. If I switch to the top end AMD video part, now it's 700w.
