Nvidia is working on a fresh set of drivers, codenamed series 90. There is some indication that the new drivers will be able to support SLI setups with more than two cards, lending weigh to the idea that high end games machines may well start boasting 2 dual-chip cards inside them, making 4-way SLI. There is, as yet, no official release date, but the money is on some time in the next month or so.
We heard that the series 90 should be the version that will support the upcoming Windows 64 bit edition as this is the next big thing in the operating system area.
I would not expect miraculous speedups from these driver as we haven’t seen that happen for a long time, but I guess they will be worth downloading once they arrive.
