Hello, this time i am running the following:
System Specs:
Motherboard: M5A78L-MLX
CPU: Amd Athlon x2 270
Graphics Card: AMD HD 5450
Ram: 4 GB
HDD: 500 gb

I want to upgrade my hd 5450 to hd 7850, but many people said that the cpu can't handle all the graphics that hd 7850 will give. And i will not get at least 30% of the performance of hd 7850 if i run it in amd athlon x2 270.
I am planning to change my cpu to FX-6300 will it be compatible with my motherboard, graphics card and will it be a good choice? TY for answers.

(I want to upgrade this because i want to play this summer, but most of my games is at low resolution and quality. And i want to have better experience..)
Thank you for replies i will be waiting for you guys. :bounce:

Yep, an FX-6300 is a good choice that will last you many years. It is compatible, but I do recommend that you go for an FX-8320 if you can spend the extra $10-$25. I would consider that CPU equal to an i5-2500k.

" I would consider that CPU equal to an i5-2500k." On what grounds? Single thread performance? Power efficiency? Maybe benchmarks.

Yes. the fx 6300 would be a good replacement for the hd 7850 and it won't bottleneck it.

Tnx for your answers guys, i really do appreciate it. I can now ask my dad to just choose it :)

Real world performance. My brother was using a Phenom II x4 @ 4 GHz until he dropped it (Don't ask lol). Then he upgraded to an FX-8320 @ 4.4 GHz. His framerates in ACIII, FC3, and Hitman doubled.

Also if you check the Crysis 3 benchmarks you can see the FX-8350 beating the i5's!

So I would consider the i5-3570k as better than the FX-8320 due to PCIe 3.0, faster ram support, and much better power use. However the i5-2500k isn't as powerful as the 3570k clock for clock, it uses more power, and it is limited to 16 PCIe 2.0 lanes whereas the FX series supports 32 lanes. Overall I would take the FX over a SB i5 since in about a year it will start beating it.

Every other game the 2500K wins - power consumption big win - I would take the Intel.

Yeah so you can get 90 FPS instead of 75. Both are above 60 and all high end games seem to favor the FX-8320 now. In 1 year I guarantee the FX starts to be the clear winner. Plus 8 cores allows better productivity anyways.

Again you are completely ignoring the fact that the i5 has pultry PCIe 2.0 support and that the AM3+ motherboards can come with USB 3.0 and 6 GB/s ports it can use. This is a huge deal for many people and to be honest I can't think of a situation where an FX-8320 would be too much power and an i5-2500k wouldn't.

I can understand someone choosing an i5-2500k over an FX-83xx on priciple, but when it costs $50 less I think it is a little silly. Both can run all games, one is much cheaper and has more features...

PCI-e 2 has not been fully utilized yet. Show me proof " Both are above 60 and all high end games seem to favor the FX-8320 now" It's also funny that Toms has the 8320 1 tier below the i5-2500k in the cpu chart.

It is funny indeed. In fact I think the chart does need some serious work in the top 3 tiers.

-Maybe an i5-3570k can keep up with an i7-3960X 90% of the time, but I doubt an i5-2300 can. TH's own benchmarks have shown quite noticeable differences between the lowest SB i5's and the best i7's.

-Also the Phenom's should clearly be a tier below the FX-83xx, and i3's are definately not just one tier below an i7-3960X. I mean LOL!

Overall I think we can all agree the top two tiers are too crowded and need to be broken up...

I fail to see how you've done my work for me. We all know 2500k OC like a beast - you show comparison for 2500k at stock - you can do better than that. I see my i7-930 at stock is almost as good as 8350 at 4.0Ghz - with my i7 at almost 4GHz I think it may outshine your precious 8350.
In fact your 3rd link shows 2500K beating 8350 in most games at stock clock.

Yeah and my "precious" (LOL ARE YOU KIDDING!?) FX-8350 can be overclocked to 5 GHz with any closed loop cooler too while you are lucky to get an i5-2500k to that level with any practical type of cooling.

You fail to see what I am saying:

-Clearly neither the i5 or the FX are much stronger than each other. They trade blows in general. They also both overclock very well.

-The FX comes with 32 lanes of PCIe
-The FX can use USB 3.0
-The FX can use SATA III 6 GB/s
-The FX is in a non-dead socket type
-The FX multi tasks better
-The FX costs $50 less! In fact my brother got it new on Amazon for $150 (Barely more than an i3)

-The i5 uses 24% less power.
-The i5 costs 25% more
-The i5 is better at single threaded tasks.


At the end of the day I will take a little more power use (Only while gaming) if it means a cheaper price AND way more features. No USB 3.0 or SATA III can be big deal breakers for anyone who wants their PC to last 4+ years. I mean look at the performance increase you get with SATA III SSD's over SII, and USB 3.0 has the bandwidth to support ANYTHING! If you would rather have a little less power use and better single threaded performance fine, but 8 cores will be fully supported within 2 years.

Last few words:

-I own an i5-3570K and believe it to be generally better than the FX due to half the power use and PCIe 3.0.
-In my links the FX-83xx is not overclocked either (4.0 GHz is stock).
-My brother went from an i7-920 @ 3.5 GHz and it traded blows with his Phenom II x4 @ 4.0 GHz (Using a stock cooler so it could have gone a bit higher). Thus if the FX-8320 doubled his frame-rate from a phenom, it would double it from your i7. In fact his Phenom II is a tier higher than your i7 (Oh and it can be overclocked too).

I see you have your head stuck in the sand "Phenom II x4 @ 4.0 GHz (Using a stock cooler so it could have gone a bit higher). Thus if the FX-8320 doubled his frame-rate from a phenom, it would double it from your i7"
you are basing this on what proven fact?? i7-920 will always be better than PhenomII unless of course the sky isn't blue in your world.

to the threadstarter. be aware that an upgrade, in your case potentially speaking, both the GPU and CPU, would require a new PSU.

and keep in mind that your board supports processors of 95 watts TDP only. in this case, if by any chance that you're sticking with that board, which i would also do if put in your position, the only highest option would be the fx6300.

i would love to know the resolution that you are playing at.

Ok now you're just getting ridiculous. You quoted the CPU hierarchy, so now I will: The Phenom II x4 955 is in the same tier as your CPU, and the Phenom II x4 980 is above your tier. Not only that, but I have used both and they both game the same. In fact they get about the same scores on intel burn test as well.

These things I listed are just straight up facts. To the OP: get the FX-6300 as it will be great and won't fully bottleneck any GPU. Then close this thread because I have said all that I can, and Moose is just trying to see how big of an Intel fanboy he can be...
