With current prices, I would accumulate sufficient funds to buy a 120gb ssd. That will be enough to store the os and a handful of games.
You will be pleased with it every day. A one hour windows update will be 10 minutes.
A 32gb ssd today is useless, except perhaps as a cache for your hard drive if you have an Intel chipset.
A SSD is 50x faster in random I/o. That is what the os does mostly. It is 2x-3x faster in sequential. Loading of your game or level will be faster. In a game, a written checkpoint may go a bit faster, but that is all.
