I have Dell Optiplex 790 MT with an RX570 8vram, 8gbs ram and a recently installed stock i7-2600k and I'm getting unstable fps in most games especially in Destiny 2 . I've checked CPU temps and done a few stress tests, there isn't any thermal throttling, turbo boost and hyper threading is on. I've also updated the BIOS and checked them. I don't think its a mobo problem. The CPU utility sits very low at 20% to 30% in games even in high priority while the GPU is under very high load. I've checked benchmarks for my specs aswell im underperforming in the expected benchmarks.
 
Hey there,

So, I suspect it's prob your ram. You've got 8gbs, and newer games like D2/BF 1-V etc use upwards of 8gbs system ram at 1080p/60hz!

Once your ram fills up it uses the virtual mem (aka swapfile/pagefile) which is on your HDD/SSD. This is much slower than your system ram and causes stuttering and FPS drops.

It could be PSU related, as the other poster has suggested, but i'm leaning towards the ram, specially for D2.
 
Monitor your system usage while gaming. Set up MSI Afterburner to show system ram/vram/CPU-GPu usage, speed.

If you see the ram maxing at 6.9-7.5 it means you are using your virtual mem which is slowing you down.

It could potentially be HDD/SSD usage. Check and see if you have 100% usage on any drives. This can also cause stuttering.

It's probably the ram I think one the ram sticks may be bad it was giving me trouble booting when I added my CPU I had to take out my ram and reinsert them. REALLY old DDR3 sticks 2gbs

I think your mobo takes 16gbs, looking at the specs. 2 x 8gb kit if you could get them, would defo help. But they are so hard to get, that the cost becomes prohibitive.

I'd suggest, trying to bite the bullet a little, and keep your GPU/SSD/HDD's and putting about 300-400$ to a new base, that will give you an all round boost, and an upgrade path. Putting anymore money into your system is just not worth it.

I don't mean any disrespect by saying that. There is some really good value out there, and for surprisingly less than you might think.
