I want to test it on Windows but it seems there isn't a fast WAMP server that fits 5.3.3.
Are there any today?
As a 'total amp' package, those would lag somewhat. However, installing the newest version of PHP from http://windows.php.net/download/ yourself should not be a problem, and as long as you have an Apache server running you should be able to make use of the PHP-version you installed.
If you require a package with the preconfigured AMP stack, you'll have to accept those will take some time to incorporate the newest versions of the software, or roll your own.
