I have eight computers I intend to build to run boinc and the HD 4650 is good, inexpensive, easy to install card (have one running already). Just wanted to check this 'Double Precision' thing before I buy more.
Thanks.

Nope. See Comparison of AMD graphics processing units, bus width is 64/128 bits. For DP it needs to be 256 bits.

Sorry to bother you again. I have two cards running now, but I am having difficulty upgrading my psu on my sff computers.
This card is cal capable, so will it work for boinc?

If BOINC recognizes it as a GPU, it can use it.

I have three computers that need low profile cards without external power sources, because I cannot upgrade the power supplies in these, as they are small form factors. I have not ordered these cards yet. Which is why I am asking.
Thanks again.

I didn't pose my question clearly.
The ATI 100-505607 FirePro V3800 Workstation Video Card - 512MB DDR3
is a card I am considering purchasing. This card was released in 2010, it is cal capable, and also double precision capable. I just would like to know it will run boinc before I purchase it, as I will be purchasing three of them.
thanks again

Again, if after you installed the manufacturer's drivers BOINC recognizes it as a GPU, it's capable of using it (at those projects that use an ATI card).

But since it shows in the list of OpenCL capable devices, it'll be able to do Brook+ (CAL) as well.

Thanks. This is the best card I could find that did not need external power, as I cannot upgrade the power supplies in these small form factors (not enough room). 400 gflops single precision, 104 double precision. 400 stream processors. 350 watt psu (my dell 305 watt psu's are running 350 watt cards now with no problem). Probably run about 40,000 boinc points a day.
thanks again.
