Hi guys ... sorry for the delay in responding, kaltek. Been busy with grandkids visiting and work stuff.
I haven't had a chance to game extensively on the new MacBook Pro, but I've definitely played LotR online, and GuildWars for an hour or more at a sitting, and I've had no particular issues. The fans do tend to come on, but that's okay with me. And, the notebook heats up to the point where I just put a magazine or book under it when I use it on my lap (usually wearing shorts). This is typical for my other notebooks as well. I do note that this new MBP stays cool during normal use - e.g. surfing and office apps.
