Would a single GTX 460 2win perform better than a single gtx 480? (excluding the amount of power it would use and the noise that it would produce)

I would really advise against that. Choosing SLI and 1gb of VRAM over a single 480 1.5gb will not give you the performance you want

not really a huge upgrade and it is completely dependent on SLI scaling correctly. Completely a waste of money over what you have.
The way that works is that in multiple card SLI each card stands on it's own so each card has 1gb of VRAM on it. In a dual card there is 2gb of VRAM on the single PCB. 1gb for each GPU. So just like if you have 2 1gb 460s in SLI, there is 2gb of VRAM in the system but each GPU core has 1gb dedicated to it.
Bus width isn't about speed, it's about bandwidth. I would guess that since one 460 uses a 256 bit bus they just doubled the bandwidth to allow for the 2 460s on the card.
You don't double the VRAM with SLI. Regardless of there being 2 x 1GB VRAM cards installed, it will only be able to address 1GB.

I understand that. Whether or not you are using 2 460s in SLI or the 460 2win you will only have 1gb usable.
The point that I was making is that the 2win cards can call themselves 2gb is because there is 2gb on the card. It is just split between the 2 GPUs. Just like if you had 2 single 460s in SLI Each has it's own dedicated memory. Either way you are looking at it you are running 1gb 460 SLI.
