1090T bottleneck GTX590?

Hello, My Gtx 590 is giving me worse performance than my Gtx560ti which is kinda dissapointing. My 1090T Cpu usage is really strange while playing making me think its bottleneck.

CPU 1: 60-70%
CPU 2: 70-90%
CPU 3: 10-20%
CPU 4: 10-20%
CPU 5: 10-20%
CPU 6: 10-20%

I've tried overclocking the CPU to 3.7 but results in blue-screen under load. 3.6 makes no different at all.

Is that all games or a specific game? Looks like the game you are playing only uses 2 cores, hence the load on the first 2 cores.

In addition, the 580 is a dual GPU card, and not a lot of games take advantage of the dual GPU's. Are both GPU's enabled in the control panel?

do you have both gpus installed at the same time, that may be an issue, especially if you havnt got sli enabled for the 590 as its a dual gpu card, or if you have it in a slower pcie. Make sure you only install the 590, in a 16x slot, and have sli enabled in the nvidia driver. You may need a clean driver install with driversweeper.

you are barely using two cores (assuming it is a 2 thread game). its a sign that your CPU is not utilized fully. hence it cannot be the bottleneck

even if your CPU is a bottleneck, your performance should not decrease. at the worst it should remain constant.

i would look else where for the problem- maybe PSU? did you reinstall driver from scratch? also did you change your games settings ?

I've alredy tried with different GPU drivers and yes I've used Drivesweeper. The 590 is the only card in my computer and it's in a 16x port. I have low fps in almost all games I try, Battlefield 3, World of Warcraft and Arma 2.

I got my 590 tested by one of my friends and it ran alot smoother, hes running a 2500k at stock.

first thing i do after i change a major hardware is reinstall windows from scratch. windows is a funny software.

what is ur PSU? like i said, there is no way to justify lower performance compared to 560ti given that a bottle neck will mean performance cannot increase and not performance will decrease. also did u change games settings?

To quote a movie: "Not bloody likely"

Your CPU is not the bottleneck.

Changed my PSU 2 weeks ago to a CX750M, Did a clean install of windows yesterday and increasing/decreasing settings doesn't really have any impact on the frame rates.

well since the card works ok on a mates PC, and you have clean installed windows, the place i would look next would be the motherboard or CPU. Check with gpuz make sure the slot is running at 16x (check while under load, sometimes power saving features reduce the link speed). update motherboard BIOS to latest. check the clock speed of the cpu is increasing under load, or turn off cool n quiet or any other power save features in bios. I'd say more likely the motherboard problem than the cpu.

checking during game clock speed will also be needed. and use GPUZ to check if both CPU is working
