Am considering getting a refurbished iMac to begin working with FCP X. There's one available with the 3.2Ghz Quad-core Intel i5 and another with the 3.4Ghz processor. Both have 8GB memory, 1TB hard drive1, NVIDIA GeForce GTX 775M graphics processor with 2GB of GDDR5 memory.
Any reason why either of these might not be ok to work with FCP?
