I have a laptop running windows 7 which has the following specs; i7 2670QM 2.20 Ghz 6MB L2 Cache 8 GB RAM 2 GB Nvidia Geforce GT540M However, I believe this guy does not perform the way it should do. Running an After effects and doing some composting slows it really down. I have an Imac bought back in 2007 and it was flawless. System almost never stuck in the middle or an app stopped responding. I have a feeling that even though the hardware of a mac is not as powerful as other systems, it handles all the work with osx in a harmony. Am I right with this feeling. Cause I'm planning to buy a new macbook pro 13" which has i5 with 3mb cache, 4 GB ram and something called "Intel Iris Graphics" At first it doesn't look like a wise choice but I am kinda on the fence. I mostly use after effect, photoshop and Cinema 4D Do you think this macbook would perform way better than my current laptop? Thank you.
