It is finally available a 64bit build of QGIS for Windows.
Using the 64bit build Windows users would likely see many improvements, for instance we already noticed that a few bugs about printing complex/large projects that were affecting QGIS 32bit are gone on QGIS 64bit.
Please help us testing this new build by installing it with a 64bit version of the OSGEO4W installer
http://download.osgeo.org/osgeo4w/testing64/osgeo4w-setup.exe
and reporting any possible issue on the QGIS bug tracker

Thanks!
