Not that great, but they're folding 24/7

Yes, that is what happens when you abuse a poorly cooled laptop, it will shut itself off to prevent damage.

I folded on all 14 of my school's imac 27' things of utter ugliness for 5 days straight when the teacher was out. LOL. I got 1.3 mil points and helped research! 
 
@Minibois this is what I call hooked on the fold

it's not even a good laptop...
it has a first gen core i3 370m...
 

I'm folding on my school laptop all day (10 or so hours a day) now. it is blocked from school so I am using a vpn
we were sitting watching romeo and Juliet and everyone else's computers were silent and mine sounds like a hair dryer and is burning hot. were charge our laptops overnight and we are meant to last through the day but if we really need we can get a battery swap. I go through three batteries a day  

24/7 around 60 on my laptop. 
 
ps i use the chrome app.

With the new Cores and the release of new GPUs, there is a lot of information floating around from various sources. Not, if any, is official unfortunately. So, in this thread I am going to post some info I have found to be pretty trustworthy as well as results I know from my own tests.
 
I invite other users to post their findings. NOTE!! Do not simply post PPD results and the like. This thread is for posting config examples that you know to work based on your testing. Yes, testing, meaning you have multiple systems, GPUs, whatever, to back up your claims. Or you have read, post links if possible, trusted sources.
 
This will hopefully allow you, the average user, who might be considering some GPU upgrades, to get some information that may pertain to your environment. Also, NOTE, all this info is very subjective to the testers environment and settings. Mileage will always vary. Most of this directly effects multi GPU configs. 
 
General Information
Unfortunately most of the info you see on the Stanford site is out of date. Much of the information is from 2013 when the new website was launched and has not been updated much. So, when reading things there, take it with a grain of salt. There have been a lot of upgrades and changes over the past two years.
 
Supported GPUs
There is a file, called the GPU White-list, that contains a listing of all supported GPUs. This does NOT mean that because your GPU is in there, it is supported. This list is updated with new cards but never has old cards removed.
 
As per the Folding Forum, the somewhat official information source, here are the currently supported cards:
 
Officially Supported GPUs
AMD -> HD 5000 Series or higher
Nvidia -> GTX 400 Series (Fermi) or higher
 
That was from 2013. I think the minimum's supported have now gone up, but I am not positive. 
 
Also the equivalent Quadro, FireGL and such cards are also supported.
 
The dedicated GPU compute cards, NVidia Tesla, Intel Phy and others, are not supported.
 
PCIe Slots
You can use PCIe x1 size through x16 sized slots for folding with GPUs. There are various types of expanders that allow your x16 card to plug into a x1, for instance, slot. Also, v1 through v3 of the PCI Express specifications is also supported. Now, here is where is gets complicated. Different Cores and Projects need differing amounts of bandwidth. 
 
In my testing, and some others, about two years ago, we found no PPD decrease when using x1 slots versus x16 slots (PCIe v2). Back then though Core17 was just coming out and there was no Core18. This has changed somewhat. If you get Core15 and some Core17 assignments, this still won't make a difference. But, on Core18 it can. Some have seen up to a 20% drop on PDD when going from x16 to x4 slots. At this point though, v2 or v3 slots don't seem to make much of an impact. So, where does this leave you?
 
If planning to make a multi GPU folding system, try and get/use as many x16 slots as possible. You can use x4 and x1 with the use of expanders, but depending on the work you get assigned, you might notice some PPD decline now on those cards.
 
CPU Impact
This is primarily a NVidia issue, mostly attributed to NVidia drivers. So, the rule of thumb when folding with a NVidia GPU and CPU folding, is to leave one core free per GPU to maximize your GPU Folding performance. In the case of AMD, it is simply recommended to leave a single core free for one or more cards as the impact isn't as great.
 
So, what is going on? Well, it turns out when Folding on NVidia there seems to be a lot of polling. If you watch the CPU, yes, you can see it pegged pretty high, but if you look at something like the heat output, it actually isn't generating much. The CPU isn't actually working that hard, just being consumed with polling queries. Apparently not having the core free can greatly increase processing time, which in turn affects the QRB bonus. But, the CPU isn't actually doing a whole heck of a lot. The GPU is still doing all the work, just there seems to be this polling mechanism for some reason. 
 
SLI and Crossfire
If you have two cards with either of these enabled, no fear. There is minimal impact on Folding from having these technologies set.
 

 
Hopefully some of you find this useful and as mentioned, feel free to add your findings. 
 
Just remember, I will remove posts not on topic and specifically containing config info.
 

 
Update October 2015
 
Drivers
As many have seen, sometimes updating to the latest version, especially when folding, is not always the best thing. One of the more current versions for NVidia is simply crushing folding. If you are on a version and everything is running tip top, pay close attention to what those new updated version are doing. 98% of the time, you don't need them as they have zero performance gain for most things. What they are doing is adding specific support for games, fixes, etc. If you don't play those games, then you don't need the update.
Just pay attention before updating drivers and be prepared to roll back if things don't go something and wait for the next round.
 
Minimum Support Cards
Officially Supported GPUs
AMD -> HD 5000 Series or higher
Nvidia -> GTX 400 Series (Fermi) or higher
 
Looks like they has been tweaked a bit, nothing official, but looks like these are now the minimum needed to get most WU's completed:
AMD -> 6000 series or higher
NVidia -> GTX 620 or higher

Woah ok, my GPU just jumped up to 47K PPD lol - Should of actually just hit that 30 minute mark since I started
As for CPU it's runnign at 4.2 on each core with 80-100% utilisation, so maybe it's just the project it's on or something

The GPU hasn't had enough time to get a correct estimate, so you'll see a much higher PPD for your GPU in about 30mins
 
Although I would have expected a higher CPU PPD  I can get ~10k PPD on my FX6300 so you should be beating that by quite a bit

Could use risers, like the custom mining machines(In fact, if somebody did this they could technically use all of the PCI-e slots, even the x1's. Imagine 7+ Titan Z's folding away lol).
 
Edit: Imagine using a custom case, risers, and this:

By far the most disturbing thing i have seen so far

Hit 100K points for the LTT team today. Doesn't seem like much to you guys with your big numbers, but I just run it on my work laptop while I leave it at the office overnight. I just can't bring myself to pay for the electricity to run my main rig for it.

Hit 10 million which was my initial goal when I started.

Started folding. At 4 work units at the moment towards LTT group.
 
I'm afraid one day I will relapse so I want a cure by then for blood cancer or any type of cancer. I also plan on working my way towards getting an education at Stanford to do research.

It's as safe as possible. Just like you blindly trust your web browser and games to be installed and access the internet, you can trust the FAH software.
 
Also, yeah, that's the link we use.

I wouldn't mind betting they are doing this so they can stagger the downloads and not suddenly have 60% of the worlds desktops hit their servers for a full Windows download.

I have 3 computers folding currently, only GPUs running
2x 7950
2x 270x
3x 280x
Another computer is currently down but with all of them I could make 800k ppd

hit 1m tonight and ranked 684

Sitting at 254, btw did you guys see we make up 8+% of ALL active users?  holy crap!
 

i have a gtx 980 and gtx 660 working fine you just have to change settings

let them sit for a little while somtime it takes alit while for them to start and wait for the WU to get to 3% it gives you a more accurate ppd

Just joined and started. B)

let them sit for a little while somtime it takes alit while for them to start and wait for the WU to get to 3% it gives you a more accurate ppd

But yes you can fold.

I would start with folding @ home and it's for a good cause so as cancer
