It's hard to sway a client to a specific direction if their earlier system was "OK" to them and the don't want risking a different system with a different builder. >_< Been there too many times so I feel your pain.
The link was specific for AMD because it was only recently that AMD GPU's had support for Adobe products, before it was all about how Adobe supported NVIDIA's CUDA but now Adobe has support for AMD cards that's why I linked to that to offset prices from an additional 16GB or RAM as well as getting a non-K CPU.
But if the build is all within budget it looks good from here and if the 750ti has 2GB of GDDR then it'll surely support 2 monitors for his work.
I'd say this is a solid build I'm just a little bit concerned about OC'ing the CPU (despite having flawless process in having a stable OC) as opposed to having solid benefits of having more RAM for the system and a better GPU for workflow acceleration.
