I used my i7 920 from 2007 till 2016 with only the GPU changed from 4870x2 to R9 280. The reason I changed is intermittent problem with booting because of RAM not being detected. I am still using the replacement till now an i7 6700K with 32GB RAM and SSD and I feel I wont be changing it for a while since it is fast for it needs to do.
