Looking to invest in a desktop. I'll need an iMac and I'd prefer to have it better than my laptop. Currently running a macbook pro, 2010 (i think) 2.4GHz Intel Core 2 Duo, 4gb RAM 1067 MHz DDR3. I semi don't wanna break my bank with this purchase but it's inevitable that i'll be forking a bit of coin. Anyways any suggestions as to where's the best place to look would help
