It's been about 8 years since I bought my computer (Windows) - a Dell desktop with a Core i7 (940) CPU at 2.93 GHZ. I upgraded it since then with scads of RAM and all SSD. But I'm sure that CPU and motherboard technology has marched onward in those 8 years. I am wondering how much of a performance boost I might expect from a CPU/m-board upgrade. This is used for LR and PS. To be honest6, the system is fast enough for me, but as they say, more faster, more better!
