A choice between two

Hello all,

Hope the crunching is going well.

My old work station has two super old graphic cards in them and really aren't very efficient. As the power supply is proprietary there isn't a lot of extra cables to attach. I'm thinking of getting either two 1050tis or two 460s as they only draw through the pcie slot. Does anyone have stats on which might be better suited to crunching? I generally do GPUgrid or seti. The 1050tis have a £40 premium on the 460 but if they crunch faster then it's worth it.

Thanks in advance.
