The answer depends on what you want to do with the XML. Generally with files that size you wouldn't want to read it all in one go. As such the following page makes an interesting read, providing a means to mine data from the file without loading it in memory. It allows you to combine the speed of XmlReader with the flexibility of Linq:

And quite an interesting article based on this technique:

Since you are already using a DOM, an alternative XML parser you could try is a SAX parser. Instead of loading the entire tree into memory, a SAX parser is event-driven and handles nodes, etc. as it encounters them.

Linq to XML is the easiest way to currently work with xml but this will typically load the entrire tree into memory which in your case with a 70mb file may not be ideal.
However there are ways around this as demonstrated in this blog post from Mick Taulty.

LinqToXml is probably a good bet if you wish to query it in memory, but if you find that you are getting problems with how large your memory footprint is you could use an XMLReader
