I have my old bitcoin machine and its doing terribly compared to my dual xeon cpu server.
is there a setting i have to change, or different team i have to join?

BOINC itself has projects that run on both CPU and on GPUs.

However, this project (Rosetta@Home) performs calculations that are not easily done on a GPU and thus it only uses the CPU and wont use your GPU for anything.

With that said, some other BOINC projects can make use of the GPU to massively speed up computations. If you're specifically interested in biology/medical research/proteins, I suggest looking at Poem@Home or Folding@Home (note that Folding@Home is seperate from the BOINC platform.) Both of these projects will make good use of your GPUs to accelerate computations.

With that said, Rosetta is a fantastic project when it comes to improving our understanding of protein structures, folding, docking, etc. and I'd encourage you to keep your Xeon server contributing to Rosetta@Home.

i read folding@home uses molecular dynamics algorithms which may be somewhat different from the algorithms rosetta@home uses, the different modelling approach may in part make the use of gpu limited (but only the researchers could tell)

As Timo and sgaboinc have said, rosetta@home can't use your GPU(s), but your 2xXeon machine is doing a great job.

The team you are on makes no difference to any settings - it's just for fun.

The projects you choose within BOINC are a different matter - rosetta@home is one of many (but the best in terms of research outputs and potential in my opinion!).

You could upgrade the celeron CPU to something with more cores - you'd have to check what your motherboard can take, but you could go up to an i7-3770K. An i5 would be cheaper and not much slower.

thanks guys , i did end up googling and found it.

so i use my xeons here, and my quad saphire's there.

thanks!
