does the reference 470 stomp the reference 560? i mean, its got more memory and more stream processors.
470 or 560?

No, because the reference 560 is at much higher clocks. Though depending on settings (like AA/res) on certain games, the extra 256MB of vram could put the 470 over the top if the 560 ran out of vram. Right now I'm tapping out my vram playing CoP Complete Mod maxed at 1920x1200 ... I'm sure a 560 would be a slideshow in this particular gaming scenario.
But generally ... no. 560 is a bit faster. However at max OC if you get a good 470 it's likely to be a little faster because it would have a lot more headroom in terms of the % OC (also hotter and louder though).
Mine, for example, will OC by 40% on the core and I seriously doubt anyone with 2x560's could 'take me'

EDIT: A side-note ... something to keep in mind about memory amount ... having 'more memory' does not inherently improve performance in and of itself. Either you 'have enough' for the gaming scenario at hand ... in which having more does NOTHING ... or you DON'T have enough, in which case your performance goes down the crapper.

i wish there was more 2gb models of the 560ti out other than palit.

I been hoping they'd come out with a single card w/2x560 core and 4GB of vram. That'd be a sick card, more desirable IMO than a 590. If they made that card and priced it at like $549 they'd sell 'em like hotcakes.
If you're getting two of 'em for SLi, then yeah for sure I'd want the 2GB models. 1GB is pretty much enough for one though.

Lets do some paper benchmarking:
1. Assume that memory overclock doesn't tangibly affect performance.
2. Assume that the cards scale the same (i.e. 10% increase in core clocks on one card would be equal to a 10% increase in core clocks on the other card)
3. Assume that the stock GTX470 performs on par with the GTX560.
A GTX470 is clocked at 607 MHz stock while the stock clock of the 560 is at 822.
Target overclock for the GTX470: 800Mhz <--> represents a 31% increase in core clock.
Target overclock for the GTX560: 1000Mhz <--> represents a 22% increase in core clocks.
Both of these overclocks are good targets for most people (some will get higher clocks, some will get lower, but I think the median overclock is somewhere near the figures stated above).
So with this at 800MHz a GTX470 will be about 10% more powerful than the GTX560.
(I didn't figure into the memory bandwidth or the slightly higher frame buffer of the 470 because I don't think either card without SLI or extreme cooling has enough power to saturate the VRAM.)
