fx8350 + gpu VS i5 4690k + mobo

Adrian_71 · Apr 8, 2015

Hi Guys,
It's time for an upgrade in my PC, so I've been thinking of buying an I5 4690k + mobo for about 350-400$, but in the meantime I came up with an idea to buy an AMD FX8350 (about 180$ in my country, plus I get to keep my current mobo 'cause it's the same socket) and for the rest of the money, invest in a nVidia GPU.

So here's the deal:
I5 4690k + mobo
or
AMD FX8350 + GPU

I'd be very grateful for any advice from users, especially amd, I know both processors have their fans, I've been watching a lot of yt material and I know the 8350 is a good processor once paired with a good gpu.

Current rig:
Phenom II x4 965 BE@3.8Ghz on SPC FERA 2*Gigabyte GA970A-UD3*Gigabyte radeon 7850 2gb*Patriot Viper DDR3 2x4gb 1600MHz CL9*SPC DEUS M1 550W*ZALMAN Z11 HF PLUS

the i5 route wont improve that much in gaming, as the 7850 is still holding it back.
the AMD route is hotter, louder, and can be more expensive.

I have a spc fera 2 cooler and zalman z11 case, so the amd should have good temps and ok db level. So in the above rig, the amd & GPU should be a better combination?

Yes. A FX 8350 and a GTX 970 would be a good combination. Net performance increase would be minimal for the i5+7850, versus quite a bit for the FX+970.

^ True, don't bother switching to Intel, I am happy with my 770 and 8350, and the FPS difference would be minimal. Get a 970 and 8350. If you don't use your computer as a full time server then power and heat is not an issue.

amd cpu plus better gpu... imo get a gtx 960 or r9 280x... both great gpu's...

hftvhftv · Apr 8, 2015

280x would perform better, but much more power.

Thanks a lot guys for all your help, I also thought a good gpu + fx8350 would provide more fps than just buying an i5 4690k. Two more questions though, I've heard something about the amd fx8350 "throttling" on my mobo (gigabyte ga970a-ud3) - I don't know much about that, could it be solved by a BIOS update ? One of the reasons for switching to the fx is the fact, that I don't have change my mobo and use the money on a gpu...any thoughts on that ?
Also, isn't it true that amd processors should be paired with nVidia chipsets ?

That would be in the case of having a bad VRM cooling solution since your CPU is rated at 125w TDP, but I would not believe this to be true for your board since it does have a fairly beefy VRM heatsink and says that it supports the 8350 on the CPU support list on Gigabyte's website, but I wouldn't recommend doing any heavy overclocks on that board. If you want an overclocking board go with the Asus Sabertooth 990FX R2.0 or Gen3 model.

It's a tough call. Ideally you'll want to do both eventually. You're at an awkward point where the Phenom isn't bottlenecking HD 7850 significantly in most games, but if you get an FX-8350 it would probably bottleneck a higher end GPU. I've got an FX-8350 @ 4.8GHz and 2x HD 7970s, but it even bottlenecks a single HD 7970 (same as R9 280X btw) in very CPU hungry games. For example in Battlefield 3 the FX-8350 will cause some pretty bad minimum framerates even with one HD 7970 and GPU usage will drop sometimes.

Meanwhile if you get an i5-4690K and Z97 motherboard, your performance also won't increase out of the gate since the HD 7850 is only being held back a little bit if at all (depending what games you play).

Perhaps go somewhere in the middle... get an i5-4570 and cheaper motherboard (you dont need to overclock, it'll still be much faster than even my OCd 8350 in CPU heavy games) and put that money towards upgrading the GPU. Otherwise IDK it's up to you.

If you think it will be a long time before you can afford another upgrade, then I guess go for the better GPU now and the FX-8350. If you think you could get a new GPU in a couple months, I say get the i5-4690K and board now and then when you can afford it get a beefier video card and the i5-4690K will support it without any bottlenecking.

What do you mean? My 8350 and 770 can run BF4 on Ultra with zero dips below 60, and a 770 is a little better than a 680 which is about the same as a 7970/280X.

That's at 1080p too

I said Battlefield 3, it doesn't use as many cores as effectively as Battlefield 4 does. For example on Kharg Island rush if I stand inside the giant smoke cloud at the first base (when the jets come by and bomb it) my fps drops to the 40s for a bit before going back up well above 60.

Nvidia's drivers also have lower CPU overhead than AMD's, so I would probably get better performance if I had GTX 770s instead of 7970s. What are your minimums in BF4? I usually stay above 60 but every so often when buildings are collapsing and particles are flying everywhere my fps will dip below very briefly.

The minimal at 4x MSAA is around 40 FPS, but at 2X MSAA It VSync at a solid 60FPS on Conquest. But really? BF3 which I also have runs like a dream maxed out even with some scaling.
