Upgrading 27" iMac?

[The Hockaday.]

Nevermind, after some more googling it seems upgrading is out of the question. Guess I'll just have to be happy with lower settings for a bit. ( if there is indeed a way to get better performance please feel free to post it here )

Ello guys and gals, I have a few, I believe simple questions.

I have a 2010 27" iMac ( I will post all of the relevant specs in a follow up or edit once I switch back to OSX. ) with 3.03ghz 1tb hard drive and 4gb of ram.

I am noticing an issue with playing a couple games ( everquest 2 and rift ) that I can not handle higher detail levels.

I am wondering what could be upgraded to be able to run these games at a higher detail level.

Would it simply be a video card?

My apologies to for my novice knowledge level in this aspect of macs =(.

Thanks for any replies!

You can find the bottleneck by running Activity Monitor (see https://secure.wikimedia.org/wikipedia/en/wiki/Activity_Monitor) during gaming.

If you need help, post the performance results of CPU, memory and disk here.

OK thanks, I'll try that tonight with task manager ( I have to run windows for the games )

Sorry to ask but, how do I post the data needed from task manager?
