Should I run the XP updates for gaming?

I recently installed Windows XP SP2 via Boot Camp on my iMac. I use XP exclusively for gaming.

I was wondering if I should install all of the updates on my fresh installation of XP. I’ve heard alot of complaining that Windows updates tend to do more harm then good at times. Just wanted to know if I’d actually gain anything in reference to gaming with the updates, or if I’d just do more harm than good. Thanks!
