Is it worth it to try and run this on a CPU only shrubber ? or is a GPU needed to really help?

For F@H, the points definitely rack-up more quickly with GPU (either Nvidia or ATI/Radeon).
SMP processing also can toss-in some good grenades (especially if you have 4 or 8 core CPUs).
However, anything will help...
As the wry old saying goes, "No single raindrop can be blamed (or credited) for bursting the dam".
My observation is: A large group of Loonies can accomplish incredible things.
At the time of this post, we're positioned to overtake Team PimpRig in about 17 hours!!! We'll be at #132 then.

Last time I tried with an ATI card, I was thrown a bunch of errors and only a few good results. Has the ATI version come along any?

the website for F@H suggests using several cores on a CPU and running it 24/7 in order to finish WUs on time. I only have 2 cores and can't run 24/7 so I'm prolly not of much help there. Throwing some wait at Muon1 instead along with prpnet to try and finish up my PSA bronze badge

Although I am an Nvidia "fan-boy", I cannot honestly berate ATI.
The NV approach is to make very fast GPU cores, while ATI's strategy seems to favor the mongolian-hoard approach (nominal speed cores, but many more of them).
Both GPU chipsets have advantages & disadvantages.
ATI/Radeon seems to be better for gaming applications.
Some of my gamer-gonzo friends insist that ATI produces 'smoother' video output (less tearing, jittering, frame-skipping, etc).
Other gamer friends will mention that NV cards produce 'crisper' video output (sharper anti-aliasing, better tessellation, etc).
NVidia seems more easily adapted to pure computing applications, though.
I find it curious, however, that ATI has aggressively pushed OpenCL while NVidia was dragging their feet (until fairly recently).
OpenCL is somewhat a 'competitor' to CUDA.
I don't see any reason why a 5xxx, 6xxx, or 7xxx series Radeon card would have [m]any issues with F@H, but I have no direct experience, either.
What I do know, however, is that Radeon cards are more likely to mop the floor with NV when it comes to double-precision calculations.
More models of ATI/Radeon are natively FP64 than the equivalent NV rival.
Having said that, though, check the card 'specs'.
F@H claims that they only use single-precision calculations (FP32), so either type of card should work.
If this is true, a FP64 card would have no significant advantage over FP32 cards in these types (single-precision) of WUs.
ATI/Radeon might me more 'powerful' in other bio-chem projects or astronomy projects that require FP64.
Yes, a FP32 card can do double-precision calculations, but it will take 4 to 12 times longer to do each calculation.
Specifically with regard to F@H, however...
ATI was first to work with Stanford, and there does seem to be a slight bit more of a "cooperative" feeling in that relationship.
What I take from the Stanford site (just my sense of it, anyway) is that ATI leads, and NVidia follows.
Many of the new FAHcore apps are built for ATI, and subsequently retro-fitted for NV.
Maybe that's because ATI seems to get their products into the mainstream market faster than NV (just my observation).
So, that's why we see ATI 'FAHcore' applications being released weeks or months ahead of NV.
I still have not seen any official announcement from Stanford about support/apps for NVidia Kepler (6xx series).
Just the usual, non-commital blathering..."We're working on it".

Le fait accompli, mes amis!
Next on the guest-list to visit the abattoir of the KWSN Orbiting Fortress is....
www.HEXUS.net
They might be made of stronger stuff; we may need...the Comfy Chair!!!

D O N E ! ! !
The Comfy Chair was NOT required!
An invitation (cordial, albeit tacit) will now been sent to...
FurAffinity
to visit the hydroponic-baboon laboratory of the KWSN Orbiting Fortress (and to relinquish position #130).
I doubt they will be able to withstand the stench, however!

There was talk of getting f@h onto BOINC years back, and as some indicated, they chose not to go ahead, after and arguably a half arsed attempt. tbh, I don't think they ever really wanted to, and were pretty much responding more to interest then anything else, with what client they did put into a closed alpha, which most anyone couldn't get into.
It's possible to run it along side BOINC, with some clever configuration, and for a time I had, but tbh I couldn't be bothered anymore... So long story short, they decided not to put out a BOINC client, and as all got said and done I reciprically decided not to fold. I'd rather not go to the trouble of configuring for 2 clients to run concurrently, or to have to baby sit them to get them both time (as an alternative). And I'd rather not run a stand alone project only... To each their own, but for my part I won't run folding now tbh, I haven't given it much thought since reading the whole thing play out, and could care less... There's plenty to crunch even without crunching for em, so no biggie....
