Hi I'm getting together a shopping list to build an i7-2600k box but want to make it reasonably future-proof as far as GPU computing is concerned. If LLR on a GPU is going to be running at multiple-CPU-core speed then I want to have the option of installing a quality GPU to take advantage at a reasonable price. In the past I have only bought cheap GPUs, even using onboard graphics where possible, so I am a total newbie! Questions: 1) If I understand the llrCuda thread, the speed is comparable to a single CPU core. Is it now just a matter of tweaking or is there a possibility that speed could improve x-fold in the near future? Similarly: 2) I've narrowed it down to 3 Gigabyte boards that sound good. From an llrCuda point of view (not-sieving) should I just get the cheapest of these three or would it be wise to pay more?
