I was looking for a GPU with compute capability >=2.0 which support event sampling for accessing the performance counters. I do have a K20 with me but the frequency scaling levels it provides is quite less and not useful for my work. The only way I can get around it is by probably tweaking the bios which may brick it.
So I was looking for other GPUs from the above list which have compute capability >=2.0. There are a lot of them, but since I am using a GTS 250 and it does provide me the necessary frequency scaling support, I was looking at the GTS series 4**,5** etc. Can anybody tell me a way so that I can verify that these GPUs would let me do the frequency scaling using nvclock (NVClock - Nvidia overclocking on Linux!) and will provide me a full range of frequencies unlike K20 which only has two memory frequency levels to choose from.
Thank You.
