GPU crunching question
Simon:
I have no numbers to compare with, but going by how the 6600 compares with the 6800, 7800, 7900 would deliver a similar sort of speedup, and the 8800 GTX may be quite a lot quicker due to its different architecture.
I'm estimating that if a GF 6600 can do ~0.5 GFlops in FFTs, then a 7800/7900 would do around 3x-4x as much. Have you gotten anyone to test your code on those cards?
Regards,
Simon.

I've got a 7950gt 512Mb to run on if ever you need it if anyway it can be of help. I'm sure you've had loads of people offer to test for you ;) :D
Increadable stuff looks like. Keep up the great work ;D

I just found (some of) my notes on a FFT project I did about 2 years ago. I am a bit rusty, but if you want an extra set of eyes to cross reference....just let me know.
and as stated before I have a 7800GTX ready and waiting...however I do have a second one coming in soon so I will be able to do SLI testing if needed as well.
