Hey guys, I'm new here and I'm looking for advice. I'm coming off of a HP laptop (AMD Turion Dual Core processor @ 2.10 GHz, 3gbs RAM, ATI graphics 256 mb) with Windows 7 freshly installed. After that being a deception, (slowly starting to bug up and return to the old Vista state of performance) I'm seriously considering purchasing an Imac. I do some graphics processing from time to time but mainly I record and edit audio. I need something that could easily support the software and decrease the latency between my audio input box and the computer registering time. I'm thinking of getting the new 27inch Imac with the quad core i5 processor. With this, I was thinking of upgrading the ram to 8gb. Knowing next to nothing about macs, would this be enough for me? Would I see more performance from the RAM upgrade or the processor upgrade? Can I add the RAM myself later? Any input is very much appreciated. Thanks in advance for your help!
