It seems that a lot of GPU problems revolve around specific versions of drivers. Though AMD has their own support structure, you can often learn from information reported by others who fold.
Up until several weeks ago, I was running version 6 on my computer and having no problems. Whilst I was on vacation, the client stopped downloading new work packets. Thinking it might be a problem with having an outdated client, I downloaded version 7.1.52. Unfortunately, that version dumped my Dell XPS 450 into a blue screen of death after a few minutes. I did some research on the boards and learned that the latest versions of the AMD drivers had not been fully tested with the latest version of FAH. So, I went online and downloaded Catalyst 11.12. I did a clean install of the driver package then a clean re-install of version 7.1.52. Running does not drop me directly into the BSoD, however, the program will not fetch new work packets:

02:28:05:ERROR:WU01:FS01:Exception: Could not get an assignment
I currently have FAH set to run the GPU only. Does anyone have any suggestions?

See the discussion here: viewtopic.php?f=51&t=21337
There was an announcement a year ago that the HD 4xxx series and older GPUs would be deprecated. No new projects are being developed for those GPUs and it has taken untill now to finish most of the projects that were active at that time. Your best options are to fold with your CPU or upgrade your GPUs. Your i7 will do an excellent job of folding with a SMP slot.
Problem solved. Retired my Radeon cards and installed two new EVGA GeForce GTX 570 HD's. Went from around 3,500 points per day up to about 35,000 - 40,000 per day.
Hardware configuration: Intel i7-4770K @ 4.5 GHz, 16 GB DDR3-2133 Corsair Vengence (black/red), EVGA GTX 760 @ 1200 MHz, on an Asus Maximus VI Hero MB (black/red), in a blacked out Antec P280 Tower, with a Xigmatek Night Hawk (black) HSF, Seasonic 760w Platinum (black case, sleeves, wires), 4 SilenX 120mm Case fans with silicon fan gaskets and silicon mounts (all black), a 512GB Samsung SSD (black), and a 2TB Black Western Digital HD (silver/black).
You are getting 40K per day with a Core i7 and a GTX 570?
I have similar config on my main computer : Core i7 2600K and AMD 6870 and I am getting around 4K per day. There is something wrong here... anyone have an idea why my throughput would be so low?

Yes, lots of ideas, but only guesses without knowing more about your setup. 1st, are you using a passkey? 2nd, please post your log so we can see more detail. Thanks.
No, no passkey... but why would that improve performance? I was under the impression passkeys only made certain that results did not get mixed with other people using the same username...?

Do I need to get a passkey?
No, you can leave it blank during configuration and the client will operate normally. But we will not have any way of distinguishing work units you completed from the work units others with the same name have completed. And you will not be eligible for the new bonus points program, currently available in the SMP2 client.
Passkey doesn't make the client go faster, just get more points for the same work done.
Points are not awarded retroactively (except when something goes wrong with a server and you don't get the correct points because of a failure at Stanford).
The PS3 is not eligible for bonus points. Projects for the GPU and some projects for the Uniprocessor don't earn bonus points. None of these count toward the first 10 WUs that you have to complete before your passkey is "qualified" to earn you a bonus.

40k, no. His 2 GTX 570's will outproduce your 6870 by a healthy margin. But on the other hand your 2600k should do noticeably better than his 965 once the passkey is qualified, so the gap may not be that large. As an example of how much the bonus adds, I'll take project 8024, which tends to be middle-of-the-road for me PPD-wise. The average TPF for them on my 4.3 GHz 3770k is about 1:00. They get a base credit of 185 points, which would work out to a PPD of 2664 w/o bonus. At that kind of a turnaround time, I'm getting 1436 bonus points per WU, for a total PPD of ~23,300. With high-end CPUs, most of the points come from the bonus.
Also, you should drop your SMP slot from 8 threads to 6. The drivers for AMD GPUs cause them to use about a full CPU core when folding, and with SMP units progress only goes at the speed of the slowest thread. I would have said drop it to 7 threads but there have been projects in the past that wouldn't run on that number.
Ok, interesting. I will do the SMP limitation to 6 threads right away. Any suggestions for an old Celeron E1200 machine using a GForce 8600 GTS GPU?
Is there an optimization guide somewhere that can be read?
I did not realize the guy has a dual 570, that makes more sense then. I am still eager to see the gains once the passkey bonus starts to apply. Should not take too long if it takes 10 WU to qualify for it.
I think I will try to get some sort of used graphics card for my Core2Quad machine, the Radeon HD4850 in it is no longer supported by Folding@home. Is there any guidelines on how often GPU support is dropped? So for instance if I decide to get a Radeon 5870, do I have to worry about support getting dropped soon?
No risk of getting dropped easily, it happens only after years at major technology changes.
The "hd4xxx or less" phase out is because OpenCL is supported from hd5xxx.
One highlight on WindowsXP needing AMD/ATI driver no newer then 11.12 because XP is phasing out too, it may be tricky to have a very new video board on a fairly old pc but hopefully is not too common (I can tell hd5xxx and hd6xxx are safe on Windows XP)
Ok, excellent. I am running Windows 7 on all my computers except my two oldest one. Will see what I can find that will be cheap and supported, Ebay should have plenty to choose from

You'll have to ask AMD that question. ATI/AMD has phased out support for the Brook code that FAH has been using in favor of OpenCL and support for OpenCL 1.1 started with the HD 5xxx series. (... and Microsoft is phasing out support for Windows XP.) Stanford can't really support folding code when the company that supplies that software on which FAH depends is no longer supported.
In contrast, NVidia supports CUDA (on which FAH-GPU) is also built and CUDA is supported on NV hardware all the way back to their 8000 series GPUs. As a consequence, FAH can support many older generations of NV GPUs but the ATI GPUs of those same generations can no longer be supported. (At times, the situation has been reversed.)
Decisions like that are made by AMD/NVidia/Microsoft/etc. rather than by Stanford.
