i hope too that some older gpus will be supported. Some of my 24/7 gpus are little more outdated (8800GT, 2*9800GTX+, HD4850 are my oldest OPENCL capable ones). I know credits vary from project to project but this 4 cards can make at POEM ~700k. Im happy they can run all on POEM and Milkyway so for real science (The faster & newer cards run @GPUGrid). BUT I hoped i can switch most of the cards at the end to WCG, not every cruncher has the buget to hold all of his crunching machines up to date every year, and i think im one of the more enthusiastic guys ^^ at the moment i upgrade to some multicore cpus to get more WCG CPU cores and feed the GPUs on POEM good enough thats expensive enough and i hope it can help in future WCG GPU too ^^ Often looked at for example HD5850 cards but wow even on ebay they are to expensive for used hardware..for a little more i can buy a new faster card ^^

BUT for now we only can wait and hope ^^ Perhaps at the start of WCG HCC GPU when it only supports newer hardware i can invest in a more "expensive" GPU(s) for one or two of the machines (Christmas or something? ^^), because it is my absolute mainproject to run Cancerresearches for some personal reason :) [or better :(]

I wouldn't hold my breath. I've only seen mid to high end cards that receive valid results. My low end Cedar GPU keeps getting BETA WU's, but upon comparing against 2 other wingmen with $$$ cards, my WU gets zapped to Invalid. So what's the problem? Poor thing hasn't made it to the "seems to work" card list. At least it gives Kevin something to list as doesn't work.

Got lucky, small wonders. I received 4 BETA Wu's last night on my slow Cedar GPU and 2 processed "Valid". Can't tell what made a difference looking at the result log, I was the wingman on both.

They would run with high creditoutput too...BUT DistrGen is not science for me only energy wasting ^^ i only compute science (since i have the right projects and hardware to hold on my RAC in case of a single projectoffline situation) and as possible medical ;) But with the possibility of compute soon against this cancer with GPU, a bit money is reserved for some new gpus WHEN i know what kind of we need.

I fail to see how any model of two or more generations-old GPUs can do better than even the low-end models of current-generation GPUs in terms of support cost to operate and to maintain at both the client-side and the server-side. Over the long-term, clients who hang on to their old-generation GPUs not only pay more for the same or lower performance, but also say "No" to paying less for the same or higher performance. Over the long term, weighed down by having to also support clients who chose to hang on to their old-generation GPUs, servers can not tune their resources to maximize the cost-per-performance advantages of new-generation GPUs.
