It's possible the 470 does better in these situations due to its larger memory interface and higher amount of ram. It could also be a driver issue. I'm not sure.

The OP specifically mentions the 470 and 5850. Those are indeed his best choices. All my "derailing" was intended mostly to discuss min FPS between those two offerings in single and MGPU configurations. Often folks who want added performance may pick up an additional card for SLi/Crossfire later so considering that is relevant. Overclocked 5850 Crossfire performs remarkably similiar to 5870 Crossfire so I added my own experiences which reflect what a good deal of reviewers are reporting.

Yet again, IMO 34/55 is more desirable and reflective of a possible smooth gaming experience than 20/70. Games always feel more sluggish to me when FPS dips to 25 or lower for whatever the reason. I feel 30FPS mins or higher are desirable. Yes, that's all opinion and preference.

I'm not an "nVidia fan boy". My graphics card history is below. You may add triple HD 5870 Crossfire to the end.

I've got an EVGA 470 arriving Monday for computer 2, so I will be able to offer opinion based on direct experience with it soon.

In any case, I hope you enjoy whatever card you finally decide on purchasing
Looking forward to hear your opinion since you can make a very direct comparison.

IMHO I wouldn't consider the 470 at all, it just seems to lack a real price/performance point of it's own. A 480 seems to be a really good option, especially if you're set up for the added nV feature set.

I also agree with the min fps being caused by the 5000 series vram limitation, once we see more 2gb cards in the field, this will become obvious. Sapphire's toxic 5970 4gb has something like 30% more performance than the vanilla 5970 2GB. This leads me to believe the hitching/stuttering you mentioned isn't a bandwidth issue it's a frame buffer size issue.

I look forward to hearing the OP's results with his new card.

Also that heaven benchmark is now pretty much pointless. It's been altered so that you can "tessellation limit" the Ati cards, which have a fixed function tesselator, and showcase nV's integrated tessellation solution. That would be fine, however, we have no info as to how nV's tessellation works in extremely shader intensive as well as tessellation intensive situations. With the ATi cards, tessellation is done separately from any shader workload.
