Hey everyone. I'm about to buy an iMac 24 but have a question. I'm a web designer + will be using the mac for work, so I can retire my poor macbook to general use instead of work.. Also, I want to be able to play some games on it (specifically Left 4 Dead, counter strike). I am planning on buying the entry level 24 inch with 2.66ghz 4GB RAM + the 9400 card in. Will this play the games I want well enough? if not, are there any upgrades I can buy that will help? Sorry to sound so noob but I've always had macbooks + macbook pros. thanks for any replies in advance..
