I would. Surprisngly, that game even runs to the point where it's playable on my first gen i7 and HD 5470 (terrible graphics card).
That's because the CPU is good. You can always turn down graphics settings, you can't change animation quality or AI performance! His CPU is the issue.
As for the "dGPU will lets your CPU perform better", actually it's the other way around in most laptops, since the CPU and GPU share a heat pipe. The dGPU puts out MORE heat than the iGPU, and it can actually make steady state performance much lower (i.e. faster for 5 min and then slower for 5 hours)
