It is plainly clear this article is not for you. You are not an enthusiast nor an overclocker.
For those who do research and build their own rigs, usually you don't need to upgrade. That being said:
It is easy to see how you can take what hardware you have and compare if you swapped out other hardware. Most people throw money at it and have no idea it's a waste. I found a couple excellent resources you can compare against a single upgrade versus a whole new rig:
userbenchmark.com
gpucheck.com
Look, I'm aware how to benchmark, compare and most importantly; have a critical approach in my everyday life, whether it's my job or computer parts. But thanks anyway. I think it's a great article.
I'm just saying that I'm long overdue with the endless benchmarks and comparisons like I used to do and I tried to be funny about it.
I've been building my own rigs for 22 years and It's honestly embarrassing how many benchmarks I did back then before I even started my games.
I had to run atleast 5 benchmark programs after each RAM tweak and 50 Mhz OC for that sweet 1 fps gain. I might be laying it on thick, but you know what I'm saying.
Nowadays I simply use sites like Techspot to compare my existing hardware with the hardware I want without fiddling with benchmarks myself. I still consider myself an enthusiast eventhough I really can't be bothered with trawling webshops for B-die kits, binned CPU's and whatnot. As you probably know, Shadow of the Tomb Raider benefits alot with RAM tweaking, but I don't care, I've never played the game and I don't plan to.
I don't render heavy threaded workloads nor do I care for synthetic numbers.
I simply like to game and my computer far exceeds any recommended specs for the games I play. But I still love building computers and get new hardware, just for the sake of having it.
