First time poster asks: I thought that the CUDA client was supposed to be eyeball scorching fast. I have an AMD Phenom II box that runs Windows XP Pro and the Dnet client. Around 50,000 in RC5-72 is the usual throughput, It has an NVidia GTX 8400 chipset for video and so I thought I'd install the new client and the CUDA 2.0 drivers and tools to see some of that performance that people passing me seem to be using... After benchmarking to make sure I was using the fastest client, I got numbers in the 19,500 range and ran Core 3 as the (slightly) fastest. It churns along at about 20,000 when the box is doing nothing else. All that to say, if I run the CUDA client, I only get 20K and when I run the regular Windows client on the Phenom II, I am getting 50K. Big disappointment. Can't seem to run both (though I wonder why), and the Windows client detects 4 CPUs and starts 4 crunchers, and the CUDA client detects only 1 GPU (though I think there are 2 to run the dual head display on this card). So what am I doing wrong? Do I need an 8800 or 8900 card to get those phenomenal crunch rates that I see in the discussion forums? Thanks for any hints.
