Even if this can fit in the GPU section, I feel more comfortable to put it here
Ok I want to use my PC that have already 2 x 260 gtx on it for an other purpose. And the MSI GT I have are quite a dam good card for folding, but my case is a skeleton ( case

) and I can profit of the top cooler fan to use my ATI 4890 with a thermalright noise less , the PC is in my room where I study, can't endure a noise.
Ok here the real question related to folding .. on my gaming rig I use a HD4890, I have a 22" but we all know the petty PPD the HD4890 give. So I look for a Nvidia replacement for it .. I have a Maximus formula III in the case, with possibility of a single gpu at 16x or 2 Sli 8x and a third slot for a dedicated physx . I don't want to put the 260 in the case for the reason, I pay extra for their good cooling, and since I will put a water block on the new GPU..it will be a shame to trash the MSI cooler of those card.
So what card or what combination of card you will suggest for good folding and good gaming on a 22", the priority is on the folding ( it's why I post here, or else I will have some, that will suggest me a 5970

)
please keep in view that I will need 2 water blocks if I use sli.
