	Hallo, I have a GeForce 9800 GT card. For one WU from the GPUGRID application i get ca. 3500 points. The card need's 19 hour for the WU. Is that a good time, or is the card slow. Thanks Heinz

Thanks Heinz Yes ... Yes ... The card is on the slow end, but you will not get better pay for your effort. Besides, it is about the science ... :) Generally I have seen a spread of about 12 to 20 hours per task on my 9800 GT and you will also probably see a slowdown of the screen as you move about ... If and when you can afford it and you want a boost the GTX 260, 280 or 295 cards are good performers ... I have not been exhaustive on looking at the actual times, but, there is not that much difference between the three as to speed (the 280 is faster but I could not tell you by what percentage) and the 295 has the advantage of pulling the same power as the 280 but having two cores meaning you can do two tasks at once (or 4 like I do with 2 cards) ...

	If and when you can afford it and you want a boost the GTX 260, 280 or 295 cards are good performers ... I don´t think the question was to buy a new card, for the money you would spend one can run a lot of hours crunching for GPUgrid with a slower card. High points are not main reason to all crunchers, some may just want to use their equipment as it is. Of course expensive cards are better performer, but the 9800GT is a (very) good performer in the situation of ongoing state of affairs we see at the GPUgrid project, if you watch power consumption, ms/Watt etc. and keep in mind the date of manufacture of a G92/G92b-chip. Why not using it for crunching ? Sorry, but I don´t like discussions in the manner "it´s good, but others are better", such 9800GT are not slow end because there are some few "high end" cards released some days ago. Every card listed in the FAQ are useful crunchers, some are more efficient than others, indeed. Argueing against slow cards in favour of high end equipment to aim for a elite crunching community is not the approach I will support. Please come down to earth, there are a lot of people interested in joining the GPU supported projects, in spite of their "low end equipment" a successful crunched workunit features the same value to science than "faster" crunched WUs, right ?

	@X1900AIW Um, you read into what I wrote something that I did not say. The question was is this a good time or is the card slow. It is a good time for that card, and yet the card is also slow. Other cards are even slower ... I understand that not everyone has the ability or interest to buy stuff just for processing, and I did not say that they should run out and buy something better. I did not denigrate the card, put down the participant nor suggest that there was anything deficient ... I simply stated that IF AND WHEN and IF YOU WANT A BOOST ... other cards do better ... And I said that because not everyone leaves their equipment on all the time, the aforementioned non-elite cruncher, and that can mean that it is entirely possible with a slower card like the 9800 that deadlines can be missed. And I have a 9800 GT, a GTX 280 and GTX 295 ... and I run them all ... so, I was simply advising based on personal experience.
