Hello, I am new to MacRumors, so forgive me if this sounds like a newbie question: I purchased a brand new Macbook Pro 15" with i7 2.5ghz 512GB SSD and the standard Intel Iris Pro Graphics card. I will definitely be doing Final Cut Pro X editing with the system and will be using it as a laptop as well as docking it and using it with 2 monitors as a replacement to my older intel Mac Pro which I will keep to use as a hard drive hub. I have not opened the box yet on this new purchase because I was reading that if I wanted to do gaming that I probably would require the upgraded video card with memory (the AMD Radeon R9 M370X with 2GB onboard memory). I was just wondering if this was true considering the speed of these new systems? Thanks for any input!
