Hey guys - ive been up in the air the last couple of weeks debating between buying the base level iMac or the one step up from base model. The reason I was thinking of going one up from the base model is that i play world of warcraft and think the performance may be better but havent been able to find too many relevant posts on the topic. Will I see much of an improvement by going up a notch and shelling out the extra $? The $ isnt a huge deal to me but I'd definitely like to be paying for an improvement and not just throwing money away. I dont do anything else taxing computing wise (just general web browsing music movies, etc.) I plan on upgrading any model I purchase to 8 gb of ram myself.
