PC is showing poorer performance compared to the older system.
PC is showing poorer performance compared to the older system.
Recently completed constructing my initial PC, yet its performance remains significantly lower than my previous machine despite having superior specifications.
Current PC details:
Motherboard: Asus PRIME-B660M-K-D4
CPU: Intel i7 12700
GPU: GTX 1070 8Gb
RAM: 2*16 Gb at 3600 MHz
Power Supply: Corsair CX750 RGB
Storage: Samsung 980 EVO 1TB, WD Blue 1TB HDD, Adata SU650 120 Gb SSD
Operating System: Windows 11, a clean installation on my Samsung 980 EVO
All drivers were downloaded from the Asus website, and the motherboard is running the latest BIOS version. XMP support is active.
When gaming, my performance lags far behind what I experienced on my old system—where I could consistently achieve 100 FPS. On recent titles like Elden Ring, I’m barely maintaining 30 FPS, with GPU usage at 97% and CPU at 32%. Monster Hunter runs at 99% GPU and 25% CPU, giving me around 30 FPS.
I’ve tested the 980 EVO using Samsung Magician and confirmed RAM health with MemTest86. Windows installation appears flawless, no errors detected.
I adjusted the PC settings to high performance and set CPU to 100%, but UserBenchmark shows I’m limited to 94%.
I’ve verified everything I know how to do. Could any of my components be faulty, such as the motherboard?
Additionally, I use a PCI extender because my GPU is mounted sideways—could the extender be defective?
Please share your thoughts, as I’m uncertain about the next steps.
Remove the PCI-E riser cable and connect directly to the motherboard. Verify your power plan and set it to default 100%. What cooler are you using? What temperatures do you experience while gaming?
The default power plan is at 100%, which makes it unclear why it's causing a bottleneck. I'm using a Corsair H170i Elite, which is definitely overkill. My GPU temperature is around 70°C and CPU is 35°C. I'm planning to connect the GPU directly to the motherboard now and will update you.
