Best Sub-$100 GPU for PPD

I am looking to pick up 3-4 video cards for folding. What are the top 3 sub-$100 video cards that pull the most PPD? ATI or nVidia, doesn't matter.
 
Most definitely nVidia.

I would say a used GTX 275, they often go near the $100 range nowadays.
 
I'm gonna put in a vote for the GTs 450 @ newegg right now for only $89.99 after MIR http://www.newegg.com/Product/Product.aspx?Item=N82E16814133343&cm_re=gts_450-_-14-133-343-_-Product. The cheapest GTX 460 768MB (my second choice) is $114.99 a full $25.00 more http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=6491183&CatId=3670. I don't know how they would compare for a dedicated PhysX but my gut tells me similar, with a every so slight nod to the GTX 460 but not enough to justify the price difference.
 
You would need at least a TX950 to run 3 275's, at which point you would be better off getting more efficient cards as was pointed out.

Don't go for the GTS 450, the GTX 460 would give you much better PPD.

You got any data to back up that claim? saying that the GTX 460 768 would give you much better PPD over a GTs 450 seems strange to me, what are you basing this on? Have you seen them compared side by side or something?. Again I'm not disputing that the more advanced architecture will give t460 better ppd performance but I sincerely doubt it's enough to be called much better as a dedicated ppd. If you get 3fps more with the GTX 460 768 vs the GTs 450 I would be absolutely shocked, however it would need to give me at least 15 fps more to justify the extra $25 you would be spending for the GTX 460 768 over the GTs 450.

I challenge you to prove your bold claim. ;)

Actually, it was a bit of an exaggeration ;)

My claim is based on how many clusters or whatever nVidia calls them there are. GF108 had 4? I believe, while GF104 had 7. I would think that this would give the 460 somewhat more significant advantage in folding?
 
I'd personally aim for as many used GTX 460 768's as I could... And the most efficient PSU possible.
Going from a 75-80% to an 85-90% PSU makes a big difference with a triple-SLI setup... Use as little power as you require and run from a USB2/3 thumb drive etc.

AFAIK, the GTS450 will push 8kppd, whereas the GTX460 will push 10-11k. The 460 can be pushed farther with an OC as well.

It just so happens Anandtech just did a full bench:

http://www.anandtech.com/show/4221/nvidias-gtx-550-ti-coming-up-short-at-150/15

The GTX 460 is %45 faster than the GTS 450. And yes, you get the exact same performance between the GTX 460 768/1GB models. This makes the 768MB model a very good value!

Simple math: if you can get a GTS 450 for $90, you can spend up to $130 on a GTX 460 768MB card and still get a better deal.
 
I picked up a GTS 450 today. I will be picking up 2 more within the next couple of weeks. I also bought a sempron 145 to run in the folding rig. I'm just doing GPU folding.

Thanks for the info, point conceded. I'd now recommend a GTX 460 but try to find a used one from the FS/FT forums of your choice.
