According to the roadmaps we've seen, it will be 256-bit

Not a surprise since Barts has 256-bit bus

Sweet! iMac Power!

Nvidia GT 540M tested

"The performance doesn't seem to be much better with 400M series parts. It is only marginally faster than its predecessors and it appears the 540M is merely a tuned up core. The GT 445M ends up a bit faster in some tests, so it appears that the GT 540M is the direct successor to the GT 435M."
