[QUOTE="SumTingWong, post: 934253, member: 71335"] rtx 30 series can run on pcie 3. Performance different between pcie 3 and pcie 4 for gpu is very small. It is the same with RX 5700 series runs on pcie 3 and pcie 4. I am not sure about RTX 40 series, but I doubt it will be minor performance different from pcie 3 vs pcie 4. Speaking if your cpu will bottleneck rtx 40 series is idk because I along with other people have no idea on rtx 40 series. For rtx 30 series, is depend on game, game settings, resolution, and fps you are looking for. 1080p @ 144fps on ultra settings, you might see minor like 10% to 15% bottleneck because your cpu is working harder than gpu at lower resolution. When you move up higher resolution, this is where your gpu is going to work harder than your cpu. Your i7 8700k is going to be fine for rtx 30 series for now if you are not looking into high fps chart like 144 but over 60 can guarantee. [/QUOTE]
