I'm of the opinion that you'll probably never need more than 512MB swap in Linux for most applications. If you install something like Oracle, then it will have a higher minimum swap requirement, but you can always create a swap file elsewhere on the file system that can be mounted as swap volume.

The swap partition is not ext3 formatted. It will be a separate partition from the filesystem. However, Linux does support a swap file method similar to the one used by windows, but it's recommended only when additional swap is required.

I agree. With 3 Gb of ram, chances are you're unlikely to often run out and require a massive swap partition. 512Mb should be ample as a kind of "safety net", unless you often open a load of photos in Gimp, for example, which can easily eat up ram. If you're not short of disk space, then have a 1Gb swap instead.
