Yeah, what Soleron said.
Of course it also depends if you upgrade the CPU and GPU independent of each other, how much each component "should" cost:
Like, say that you plan to keep the CPU for 3 years but upgrade the GPU already after 1.5 years (which is my personal preference), then you don't necessairly have to put as much money on each GPU - but instead the combined money spent on the GPUs will still be a lot more than on the one CPU.
So, two version for a PC that you want to keep alive for 3 years and be able to run the latest games:
Version 1 (my old strategy):
CPU $150 - lifetime 3 years
GPU $400 - lifetime 3 years
or
version 2 (my current strategy):
CPU $150 - lifetime 3 years
1st GPU $200 - lifetime 1.5 years
2nd GPU $200 - lifetime 1.5 years
