Need advice on my current set up

[Tomlintm]

hello all i been watching linus tech tips and quickies and NCIX for a long time now and i desided to come and ask a few question maybe you all can help me

 

well here is my question

 

i am starting to add more screens to my computer recently to do eyefinity at a res of 5760x1080P with 3 AOC 22' 1920x1080P screens DCR is 50,000,000:1 on a Sapphire Radeon R9 280X 3GB

cpu is a FX-4300 3.8ghz overclocked to 4.543ghz with 8gb of ddr3-1866 ram on a asrock 990fx extream 3 motherboard and im curious is my cpu or anything bottlenecking my pc at all

The FX-4300 will certainty be bottlenecking the 280x.

[Tomlintm]

why you say that just curious if you dont might explaining bc its all confusing me

You should get at least the fx-6350, but the fx 8350 would be way better. R9 280x is too much GPU for the fx-4300

ya i kinda figure it was havent had much issues since i always had 1440x900 19 in screens but im starting to see lag now in games with the higher res eyefinity at 5760x1080P setup

Heyyo,

Definitely agree with the others, get either an AMD FX-6300 series or FX-8300 series CPU... then if you wanted to upgrade further? Wait for the AMD 300 series to release or get a GTX 980 to drive those screens... if budget is an issue though? You could always try to find a used or cheap AMD R9 280X and do CrossFire since that ASRock board supports it.

As a rule of thumb you should always match CPU and GPU a bit. A high powerful GPU and a cheap CPU is a poor choice. And the more you go down in resolution the more you bottleneck a GPU with a CPU.

I use a 5960X with a 3way GTX980 SLI. Now you could say I am the king in 1080p... sorry I´m not, my CPU bottlenecks the 3 GPUs. Of course my PC is so powerful in games that you can´t really see that. But in benchmarks the CPU chokes out the GPUs.

Same will happen with a FX4300 and a R9 280X but you will see that in games. Besides that this CPU is due to it´s totally outdated architecture a big problem for CPU intense games like ArmaIII or WoW.

ya i starting to agree i did some test yesterday after i posted and tested my pc with my new setup with maybe 2 games at the most

 

ultra settings fullscreen at 5760x1080 - with out my overclock and stock clock at 3.8ghz and memory at 1600

 

dirt 3 - 55-60FPS

 

Grid Autosports -29-37fps

 

so from grid autosports my fps was alot higher with 1 monitor then with 3 1080p and from the test i broke down and over nighted a fx 8350

Since you had the FX990 board and all other components the FX8350 (I hope you have a good cooler) with the R9 280X is definitely the right choice. If it was a fresh rig I would have recommended Intel´s i5 though.

The R9 280X will work fine with the FX8350. The only things that will still stay the same is the poor single core performance, but I guess you will be happy since this CPU is a big jump to a FX8350, so enjoy .

ya i diffidently have a good cooler i have one that push polls 2 120mm fans it awsome it keep my overclocked fx4300 from going over 120-125F on high demand games so its all good

Yeah you´ll be fine .

im not sure if this is a issues but i see now fps gain going from a fx 4300 to a fx 8350 im still getting low fps in grid auto sports you think my gpu is to weak for 3 monitors
