Where's my bottleneck?

CX4Life · Nov 12, 2015

Hi there, I'm running a gaming rig I built about 3 years ago and it's just starting to show its age. I can no longer run new games on maximum settings at 1080p and get a consistent 60 fps. My rig:
CPU Intel core i5 3570k oc'd to 4.3ghz
8gb ddr3 ram (corsair, I think)
Z77 mobo
800 watt corsair PSU
128gb ssd
1 tb hdd
2x sapphire raedeon 7850 w/ 2gb in crossfire setup, oc'd to 960mhz
Lots of fans!
Windows 7 64-bit

I actually put an r9 in it a year back, but got lots of artifacting, and sold it to get the second 7850.

Is it time to change to the latest CPU architecture? Or just upgrade graphics? I don't do much multitasking, but if another 8gb of ram would be helpful, I'm not opposed. I'd prefer to ditch the crossfire setup, it definitely has its drawbacks...

Thanks for any input! Let me know if I left something out.

Cpu is still OK, you can maintain your 8gb ram if for gaming only

Get a bigger and badder gpu

What makes you think the CPU is bottlenecking? IF anything the old CFX config is showing its age, I'd upgrade to single more reliable GPU setup like a gtx 970 or 980ti depending on what your expected graphical output is. You CPU is fine though.

Also that last time I tried crossfire on the 7xxx series it was a mess, microstutters everywhere and nothing but frametime latency issues, def not

What PSU make and model? What games are unsatisfactory?

An i5-3570k is good enough for GTX980 SLI except maybe in a handful of exceptionally CPU-intensive games. You wouldn't gain much from upgrading the CPU.

jjb8675309 :

PSU is actually Corsair HX850. Project Cars experiences big frame drops depending on the number of cars on track, Fallout 4 runs in the 30's with Crossfire enabled and in the 40's with it disabled. One of the many reasons I'd like to get away from crossfire...

Yeah I would blame crossfire personally I've never had a good experience with it. SLi is another story but personally I'd sell those GPUs and buy one strong GPU. Everything else about your system seems fine.
