I thought the 57xx series wasn't good because it didn't have double precision or somethin.

They work just fine on Collatz though.

Well we will see how the 5770 compares to the 4870's

I wanted to get more of the 4870's there no where to be found
Even this 5770 was the Last one in stock

The 57xx series of cards are single percision and won't work with Milkyway. The good news is that it will work with Collatz but Collatz give out less credit.

D#!&!t Well what about Cosmology@Home
and how do you or I tell What Works Where

It seems to me that you have 2 choices. Either take the card back or run Collatz. The only other project that will use it is GPUGrid but that is with a beta application. I would return the card and wait for a 58xx series card.

To find out what works is mostly done by reading the message boards on the projects. First check to see if there is even an application (in this case ati) then read everything you can about it.

The alternative is to take the easy way out and just ask me.

OK back it go glad I did not open it before you gave the Word
So 48's and 58's are OK
I seen a few 4850's around should I get them instead

4850s will get you about 50,000 a day on Milkyway but I would try to get 4890s. They are not much more expensive and use about the same power and they will get 90,000 to 100,000 credits a day each.


Actually it's 38s, 48s, and 58s at the monent. Here is a little known tidbit. If you are running old machines like some of mine that have an AGP slot, there is hope for you too. ATI makes an AGP version of its 3850 that will work too. Price about $100.
