are you guys ever going to incorporate ati gpu's into boinic's software or is it going to only ever be NVIDIA cards?
i know that there is 3rd party software out there to use ati stuff but im not to keen to use it yet.........

You are confusing BOINC and SETI

BOINC long ago 'incorporated' (detects) ATI GPUs
And you can see that your is detected (Coprocessors AMD ATI Radeon HD 5700 series (Juniper) (1024MB) driver: 1.4.1664)
http://setiathome.berkeley.edu/show_host_detail.php?hostid=6239582

It's only that not every project (in this case SETI) can use them (have no stock app for them)
(and there are projects which can't use any GPU not matter NVIDIA or ATI)

ahhhhhhhhhh i see! sorry for the noob question. i was led to believe that boinc only worked with nvidea cards (3rd party sofware excluded).

what is the reason that seti has no stock app. for them then? if i may ask...
again,sorry for my noobiness!!!!

I think only 3 people work at the SETI@home lab.

In fact the initial standard SETI CUDA app was written (ported from CPU version) by NVIDIA programmers.

All latest modifications/refinements were done by jason_gee (and only some of them incorporated in the >1 year old standard SETI@home Enhanced v6.10 (cuda_fermi))
After several years of experience with CUDA programming jason_gee have now direct connections with NVIDIA, reports to them many bugs in their drivers and receives from them the newest beta/alpha drivers (in NDA (Non-disclosure agreement)) which are not available to the public (to test and debug his modified/Optimized CUDA app).

ATI refused to help SETI@home lab to port the code for their GPUs
(and GPU programing is very different from CPU programing)

To me it looks like that the new SETI@home Enhanced v7.XX (in test now on 'SETI beta') is/will be made almost entirely by jason_gee + Raistmer + others from 'The Lunatics Team'
(But I have no internal connections to 'The Lunatics Team', some of them or from SETI@home lab will know better;
I don't know will Raistmer's ATI OpenCL apps be accepted as stock (standard) by SETI@home lab)

The openCL for ATI would be difficult because of the different apps required for different generation of ATI GPU. Its unlikely that Seti would spend the time porting the ATI GPU apps when they haven't done the same for the Lunatics CPU apps
