Don't believe all the hype. They are only superb for certain problems, primarily those which are naturally suited to 32-bit SIMD machines. That said, if you have such a problem they are very attractive.

I've been looking into these things for the last couple of months.

One would also need to port all of our number-theoretic integer
arithmetic to floating point.

How much memory do they have?

Some parts of NFS are very well suited to SIMD.

Not necessarily: they have 32-bit integer and 53-bit FP arithmetic. Still no useful byte-wide memory access, so sieving is not obviously a good application.

4GB per C1060 card; four cards interlinked by PCIe can be attached to a single motherboard; there's a box called an S1070 with four cards in it of which you can attach two by PCIe to a motherboard, but that's a bit more expensive.
