I just found this review with is quite new, they does test almost every Physx config possible, its in spanish, but you only need to look at the screens http://www.chw.net/2008/12/ppu-vs-gpu-para-physx/all/1/ Btw, there is missing the higher configs with gtx260/280 cards, but you get the idea.
Nice find, I wish they'd tested at higher resolutions though as it might have made a big difference to the results.
I think so too, I think this is why the 9800GTX is frequently at the top, even above the 9800GTX and 8800GT
9600GSO looks to be the sweet spot from my point of view. But let's face it, having to pay extra for SLI MBO, and for 9600GSO card just to do Physx in several lousy games.. That's 170$ where I live just to get acceptable Physx performance. Not gonna happen so soon :/ And this is hardly every combination, there's no single ATI card there And they should have included benches with all cards doing both graphics and physx on one card. Just as a comparision..
You don't need an sli motherboard for PhysX. Plus in the article they were using Vista, which means no proper ATI + Nvidia support in the same system.
they didnt tested ati nvidia there is a ghost in the brains that this wont work btw ati nvidia works with xp64 drivers on vista physix should work too didnt tested yet but dx10 dont work than anymore
