So at christmas I bought a GTX 1080 ti, then a week ago I bought an i7 7700k, During the period between getting the 1080 ti and i7 7700k I had an fx 8350 with 24gb ram, I was experiencing low performance and stuttering, now that I've got my i7 7700k the performance has increased slightly but I still experience the same stuttering, the stuttering occurs when I select an army in total war warhammer on the campaign map for example. I don't think the problem is the graphics card, increasing or decreasing settings/resolution has little to no effect on the framerate, and I don't think it's the fact that I have only 8gb of ram because on youtube videos 8gb of ram will still allow for better performance than I have right now. On cinebench I reach 950 on the cpu benchmark, and I was able to reach 135fps on the valley benchmark with a minfps of 45.

B250 and an i7-7700k aren't exactly a great pairing. Check power consumption of the CPU, if it is quite high the CPU might be throttling in the motherboard. You might be able to adjust some voltages to reduce the power requirements or change the power limits set. Ideally you should consider a Z270 motherboard with a decent power delivery setup.

If you simply dropped your hard drive from the AMD system to Intel, that can also cause unexpected performance issues. A fresh install of Windows is recommended when swapping hardware.

What about FPS change?

For what it's worth there was each test was performed with a different driver version. That could change 3dmark's scoring and in game FPS or possibly just the score. It's your average FPS with at least a few AAA titles. Badly optimized games and online games aren't recommended for testing.

Are you using a SSD?

First off a 7700K will bottleneck that card if you overclock the card and may still do so at standard speed especially if the 7700K is still stock. Next you need 16gb of RAM to get the best out of a lot of triple A titles these days especially with a fast card and CPU.

Try underclocking the card as this will give the CPU and memory less work to do, the fact that altering the resolutions is having no effect on framerate suggests a bottleneck.

Load up a benchmark called 3dMark Vantage, this uses all CPU threads. Play with what you can adjust such as memory timings etc to get the best score, this should improve your game. Again underclocking the card will probably help and tighter memory timings are not always the fastest for gaming, they are almost never the smoothest. If your ram is on command rate 1 try 2T.

Ideally you want a Z270 motherboard and another 8gb of ram at the very least, if you hadn't already got 2400mhz ram I'd say get at leat 3200mhz for that CPU as it likes fast ram. With a Z270 board you should be able to game at close to 5ghz with decent cooling and don't forget to play with the north bridge as that makes a huge difference too.

What would be a high power consumtion? On GTA 5 I get up to about 41w, I have the voltage set to 1.25 and turbo turned off.
