^They never made 2.5GB 470's, GF100 didn't last very long, AMD beat Nvidia by 6 months, but Nvidia refreshed so dang fast they actually beat AMD's refresh.
Meaning I'd have gone with a WS revolution for my board instead of a pro. I'm a fps whore so I would want a GPU for each screen. I could do TRI with 470s, but my vram is going to prevent some settings regardless of how much gpu power is there. I'm also an OC junky which means I'd have needed a bigger PSU.
480's were still $400+ I believe when I got my 470, that wouldn't really be an option, 6950's weren't even out then, and 5xxx series with 2GB wasn't really an option. Even still at $300 for the 6950 2GB.. any other way I went but the way I did I would have had to pay considerably more money.
I think 2GB 6950's would have been a better option, but it's hard to say since they weren't even out at the time. The 6950 2GB cost 70% more than the 470, marginalized later of course by the water block, but at the time it really didn't fit into where I was trying to go. It was still pulling 200+ watts, which would have ended up directly in my room without water, and they don't get the boost Fermi did from water so the gains wouldn't have been as nice.
Now that you've mentioned it I'm not really sure what I would have done differently. I'm by no means suffering atm with my res/setup. I do have to turn some additional settings down in a few games if I want to maintain at least 60 fps. I do know AMD's cards would perform better at this resolution because the side screens pretty much just add 200% more textures and AMD's design is simply better at handling textures. But the cost difference is hard to negotiate, and I still would have wanted to go water because when you look at the 6950/70 overclocked/volted it starts to really pump out heat.
Meh, I dunno anymore. I do know this time around I'm going to pay close attention to more than just 1080p performance, overclocking, tessellation performance, while of course watching for really good deals and f/s sections of forums.
