No less than 50GB with 60-80GB.
No idea how big the games will be and then there are the benchmark tools and such but it takes 10-12GB of free space on top of Windows; page and hibernation also eat up 8GB or more.
And be sure to leave 25-30% free on the Mac side.

Here's my advice, I have a 500GB HDD. I partition it half, and half. I give exactly 250GB to Windows and 250GB to Mac OSX. Problem solved. You have plenty of space to game on Windows, while keeping plenty of space on your Mac.
