I'm building a gaming computer and I'm thinking about getting a FX-8350 instead of a 4670K. The motherboard I get will either be a Crosshair V Formula-Z or a Maximus VI Hero. The Crosshair has PCI-E 2.0 while the Maximus has 3.0. Will this make a difference in performance? I will have a GTX 770 graphics card, and I plan on this build lasting me a long time, like 6 or more years probably. I will switch out the graphics card but that's probably about it, I may add a sound card later on. I may also be able to get a 4770K if that will be a better for a longer-lasting computer performance wise for gaming. Thanks for your time and help!

You will not notice a performance difference. I think a 4770k will be a better choice if you can afford it, but a FX-8350 will be just fine ;) .

The difference will be unnoticeable. Today's graphics cards are not powerful enough to saturate 2.0 PCIe, and you probably wouldn't see much bottlenecking in SLI either.

Umm getting a 8350 over and 4670k is a bad idea your going to bottleneck your 770 in cpu intensive games

Are you sure about that? From what I've read next to no games are CPU intensive anymore, most depend on the gpu. Correct me if I'm wrong, that's just what I've read.

As for PCI-E 3.0, is it predictable that in about 3 years graphics cards will take advantage of it?

a fx-8350 would not at all bottleneck a gtx770;what it will bottleneck if there is a hd7970 instead of a gtx770
there was a rticle on tom's hardware few weeks ago in which they proved that fx series cpu bottleneck their own gpu's(i.e., radeon gpu's)and are less bottle necked when paired with a nvidia gpu

I'm leaning towards the FX-8350 because I read that next gen consoles are using AMD chips and games may start to run better on AMD. I also read that current gen games are single threaded where Intel excels, but next gen games will most likely be multi threaded. That's just what I read so I don't know the truth behind it, but EA announced Battlefield 4 will be optimized for AMD CPUs, APUs, and GPUs, so that may indicate some of what to expect from next gen games. I probably sound like a blabbering idiot though.

well to be future proofed i would definitely recommend u to go with haswell;i also like amd but u have to accept it that the haswell is much better and for ur information upcoming games like BF4,ASC4 may be optimized for nvidia or amd gpu's and not amd or intel cpu's and as i said earlier fx-xpu's less bottleneck nvidia gpu's,so if u want to save money then go for fx-8350 and a gtx770

I'd like to get the i7, but I don't know if I can afford it. The i5 seems to be the sweet spot for gaming though. I'm hoping for this build (everything except gpu) to last me at least 5 years. I feel like for that long the i7 with its 8 cores or FX-8350 8 core will be more suited. They would probably bottleneck gpu performance later on though. I'm starting to lean towards Intel again for PCI-E 3.0 because it seems best suited for the time I plan to keep my system. This is my first build, so I am not very experienced in things like this.

http://www.tomshardware.com/reviews/crossfire-sli-scali... I believe this is the article you are talking about but was 2 months ago rather than a few weeks. It's not exactly what you said. The 7970 does better on both amd and intel vs a 680 though not by much. But it also shows the i7 with better performance so the fx does bottleneck. Amd cpus do prefer sli rather than cf but imo sli is better period vs cf. If you are going with a 770, go with intel.

I'm starting to lean towards intel again, but my concern is games using more than 4 cores. Will that happen before my system is obsolete? My budget doesn't really allow for an i7.

As of now, no.

6 years is a long time. I doubt any build today will be future-proof for six years.


nsaylor95 said:

There are games that are CPU-intensive as well as both CPU- and GPU-intensive. For example: BattleField 3.


nsaylor95 said:

Probably. But I am neither psychic nor a time traveler so I cannot say for certain.


nsaylor95 said:

Much further down the line. But six years is a long time. I highly doubt you will have this same build in six years. By the time multi-threading becomes popular, you will be getting a new build.

That depends on the definition of optimized. Being optimized doesn't mean it is better than other contenders. And would components optimized for a single game influence your decision? You are keeping this build for some years and do you see yourself sticking with BattleField 4 exclusively for all those years?

You buy new parts and upgrade. That is the way technology works.

yeah k114 i meant that fx series prefer nvidia gpu's more when in sli
nsaylor95,get the 4670k and u wont need to upgrade anytime soon,currently no game requires more than 4 cores and u would be more than fine with a 4670k and you wouldn't be bottle necked even with two gtx770's as u can O.C the cpu

Thanks for your input ksham, you have good points. I'm leaning more towards a 4670K i5 now. Thinking about it, my build probably will change in less than 6 years. I don't see myself purchasing a new motherboard/cpu for at least 4 or 5 though. Well, honestly I have no clue but it'll be when it starts bottlenecking my gpu. I'm just curious if AMD will have a performance gain over intel because of the 8350s 8 cores and AMD being the cpu of the next gen consoles. From what everyone has said so far,it seems like nothing will change, but what I have read and what everyone is saying on here doesn't agree. I'm torn between the two.
Sorry for any typos, I'm on my phone now.

the 8-cores would be more effective in editing,3d modelling e.t.c. along with gaming but still it's amd's best fx-cpu in the market to date and u can also go for ti or wait for amd's fx-9590(correct me) cpu

The problem with the 9590 is that it won't come out in time for my build. I'm ordering the motherboard and processor during the last week of this month.

then go and get a fx-8350 and gtx770 and you would be more than fine.....fx-8350 is AMD's fastest fx-cpu till date

Not to be rude, sorry if it seems that way, but a few minutes ago you were telling me to get the i5, now the 8350. From how I see it, it really doesn't matter either way for what I'm doing, right?

and the 9590 is probably gonna cost 900$ if we have to believe early pricing.

Terribly overpriced if that's true. I see you have the 4670k, how do you like it?

never mind,earlier i was recommending u the i5 bcoz, u said that that u want a pc that would last long and from the beginning u were leaning towards the fx-8350. i didn't get you" From how I see it, it really doesn't matter either way for what I'm doing, right?"will you pls tell more clearly

Sorry, what I mean by that is if I get either the i5 or 8350, it won't make a noticeable difference in gaming, will it?

to be frank,"NO" becoz the gpu will perform evenly on both the cpu's

Thanks, I think I'll get the i5. Like you said it'll probably last longer and the pci-e 3.0 may save me from an early upgrade with the AMD. Thanks to everyone who helped!
