Hey guys, I recently slightly upgraded my pc with new CPU and DDR4, so for those who might be curious to see if there any significant difference in performance on the same GPU, here I come with some of my examples.
Before: i5-3570k, 8gb DDR3 1600mhz
After: i5-8600k, 16gb DDR4 3200mhz
Baseline - 4K resolution, no overclock and just a GTX 1080ti as GPU.
In the first example, we can see that CPU is actually making a huge difference, AC Odyssey on everything at high except volumetric clouds on medium:
So yeah, it's just confirmed statement that CPU and faster RAM is really important in open-world games. But in the second example, we can see that not all games will fully utilize CPU advantage and mostly GPU bound, Shadow of the Tomb Raider with everything on highest and SMAA T2x:
So I can confirm it really depends on the game. If you are not going to play openworld games and have decent enough CPU, it might be worth to just upgrade GPU and wait as long as you could tolerate frame drops before upgrading the rest. Problem is, most of the modern AAA junk is openworld now, so if you are still rocking 2000-4000 intel gen it will be hard to ignore the upgrade for longer. I honestly wanted to wait for whatever next after 9000 series in intel pockets, but I had to get new PC ASAP so I've upgraded now instead.
