What I think I am hearing everyone say is you can run either GW or Pulsar#1 on your GPUs but they don't "share" very well?

So you should pick one or the other but not both.

Which means run one on the GPUs and one on the cpus?

CPUs are way slower than GPUs, so it's pointless getting them to do stuff that your GPU could do.  But Einstein (I think it's the only project that does this) allows you to not "Run CPU versions of applications for which GPU versions are available" - it's in the project preferences on the website.  This means your CPU will only do stuff that cannot run on a GPU.

Right, you can run both GW and pulsar GPU tasks simultaneously on a card, but they will slow either other down, so it is not an efficient approach.

While also true that GW CPU tasks are inefficient compared to GW GPU, you can run pulsar FGRBPG1 tasks on your GPU while running GW tasks on the CPU as a way to contribute directly to GW analysis, if that's important to you. One GW CPU task will keep one thread/core fully occupied. I have set my host up to do this at times, but my CPU resources are limited and it generates a bit more heat (~20W per CPU task on my system), so I don't double up that way in the summer months (or if I'm feeling miserly).

As I said I bought mine for only $100 which is a used price as well.  In fact I've bought several used gpu's lately all thru FaceBooks Marketplace and from people near me.

It depends on what you choose - you might factor in electricity usage, price, flops on double or single precision etc.  The best one for me was the 280X, which I bought four of.  I buy everything through Ebay in my entire life except for food which is Tesco home deliveries.  Ebay is easy to use, loads of choice, and a good price.  Ok, I forgot Gumtree.  If I want a 2nd hand washing machine or some left over bricks, I look on Gumtree, it's like a local Ebay for stuff too heavy to ship.  I never understood using Facebook to buy things.  Facebook is a chatroom, it's way too complicated to find and arrange purchase of things.  On Ebay or Gumtree I can type what I want into a search, and if it's large and I want to pick it up myself then I can ask for things within x miles of my address.

As far as which Project you run that's always one we crunchers have to make. I would love to put my AMD cards on  Asteroids but they don't have an app for that so they are elsewhere.

Is it just me or does Boinc get addictive?  I'm putting way too much money into this.  I get things running then think "but I'd like to run that project too", or "they've got a really cool new sub project I want to put more power into". 

YES it does!!! I'm at the point now where I'm trying to figure out which Project to run but have too many choices to make!! I have 15pc's running now and some can run this  Project but not that Project while others can't  run either of those. I'm also on a Team and trying not to pass my Teammates, just because I can, so that adds into things too. I will pass them if they quit a Project but not if  they are actively crunching it, I believe in the axiom 'just because you can doesn't mean you should'.

Agreed, apart from the teammate thing, I don't get why you wouldn't want to pass them.  A team in formula 1 could have one driver passing another.  If one can win the race and beat other teams, then they have to pass the rest of their own team first.

Calling all volunteers! Now

Calling all volunteers! Now is the time to jump into GW GPU crunching because the current batch of GW GPU VelaJr1 tasks can be run rather quickly.  An RX570 at 3x (gpu utilization factor of 0.33) has average task times of 11 to 9 minutes, while a GTX-1080 or RTX-2080 can get one done in 7-8 min. As discussed in that linked forum, a paucity of hosts running those tasks is resulting in those that are not (yet) being assigned a wingman to provide a quorum of two to validate the tasks. At least that's the case for me with my growing "Pending" list.

Yes my pending list is

Yes my pending list is predominantly those Velajr1 task awaiting a wingman.

Sorry I don't have many 4GB

Sorry I don't have many 4GB cards (just one and it takes half an hour to do a gravity).  I've got it set to take whatever the server gives me (and the 3GB cards to gamma only).  Why is it if there are so many gravities to do that I get loads of gammas on it?

Oh I could easily pass any of them but that's not being a good TEAMmate, they earned their spot at that Project and why should I knock them off it just because I can. One teammate had over 20 million at one project while I had 3.5 million, 3 weeks later I had over 10 million and stopped. I did pass another teammate at another project during a challenge but then stopped and let him pas me back again after it was over, I passed him in under 4 days. At Collatz if I put every gpu I  have on it I get close to to 60 million credits per day.

PS i also like F1!!!
