I have 2 computers qx9650 with a 295 doing GPUGRD
i7 920 with a ATI 4870x2 doing MW
I avg 20000 a day with GPUGRD
I am now avg 50000 a day with Milkyway
I was only doing 4000 a day till I started using the new Gipsel 0.19f code with the ATI card

I HAVE READ a lot about the diffences between the cards but is it not time someone though about doing some pararall programming.
The MW jobs were taking 1 to 2 hrs now are taking 2 to 3 mins
I hear a lot about the No of shaders per card but if you read below perhaps ATI ?? cards may have a case.
