I'm finding i rarely game these days and this PC seems to spend most of it's time encoding to x264 for XBMC so wondering if there's a cost effective way to get more performance out of it. I could sell my current CPU ([email protected]) and Mobo and pick up an FX 8350 for little outlay but would it be worthwhile or better just putting more money towards it for a 3770K?

Edit - just noticed my older mobo has support for ivy-bridge, z68ap-d3 board running the F8 bios atm. That would put the upgrade cost around the same for either CPU. Not sure how overclocking would go on it though as it isn't spectacular even for the 2500k.

AMD is the only best CPU for Video Encoding, i have an FX 8120 this is my build and it is fast, quiet & reliable:

Zalman Z9 Plus Case
CD/DVD COMBO Drive
Corsair TX650 PSU
Corsair H60 Hydro Cooler
Corsair Vegenance 8GB 1600MHZ
HyperX Blu 4GB 1600MHZ
Gigabyte GA-970A-D3 (SOCKET AM3+)
AMD FX-8120 Bulldozer(OC'ed to 4.4GHZ Cooled at 14deg idle)
Nvidia Geforce 8600GT 1024MB(Upgrading soon)
Hitachi 1TB 7200RPm
640GB Western Digital

Will be getting an SSD Soon. i have this build now i built it last year Summer July 2012. it is Quiet and plays a few games like Black ops 2, MW3, Hot Pursuit ETC... Has never been above 50deg on Full load with prime95.
 
Heh would like a little more input than that but thanks anyway GamerX.

Some of my files can take a good 5 to 10 hours on my current setup to encode and still have 2 x 2TB drives full of 10-50GB files to get through nevermind my DVD's, so some advice from those with 8350 and 3770k experience would be fantastic.
 
Could always buy a 3770k, see how you get on it with it (Overclocking etc) if you're unimpressed DSR and go for an FX83 set up.
Or change your encoding habits to software that can offload to the GPU, although I'm pretty sure hardware accelerated encoding isn't exactly in a great state of affairs.

Seems a rather bold statement do you have any info to back this up?

Corsair H60 Hydro Cooler
AMD FX-8120 Bulldozer(OC'ed to 4.4GHZ Cooled at 14deg idle)
Do you live in Alaska?:D

I hadn't thought of that, seems like a sound plan.

I use MeGUI for the encoding. I've tried other apps such as Freemake that use DVXA and CUDA and while they are faster it's hard to tell what from as the quality they put out is poor in comparison due to them using much looser settings for the encodes, chances are most of the speed comes from that and i believe x264 is CPU bound anyway. Megui gives full control and the command line lets me add parameters that aren't in the options.
 
 
Hi GamerXesr, I could be wrong but unless your room temp is about 10c i would say those temps are reporting wrong, maybe someone more knowledgeable could explain why?

Sorry But,

you are wrong, my room temp is 25 deg(c), I have done all sorts to my PC like a water cooling system and over 7 fans all around the PC with fan controller on 100% speed.
 
Seriously dude ,if you're cooling with a corsair H60 and your ambient temp is 25c you can't be @ 11c.

Edit, If you are right I'm going to get me one of them there coolers :)

No, you're wrong, it's a false reading, you can't be cooler than ambient unless you're using exotic cooling like a Water Chiller/Phase/L2N/DICE.

And you haven't done a watercooling system either, you have an AIO watercooler, high end coolers will best it.

AMD's "Core Temp" has been given inaccurate results for years now. Under load it's still only an offset temperature and not a true reading too.

He's not right, so no worries there lol.

There are no temp sensors in AMD CPUs hence the core readings are usually false. You need to look at one of the TPIN ones which will be the overall CPU temp (and what the 62c limit is based on).

What's your current board now OP? Surely if your older board can support IB, your current should as well?

And I would go for a 3770K if you can, should be the cheapest route.

Think he means his current board supports Ivy.

Although there's a lot of debating about the AMD Temps, the CPU Temp is the socket temp, and they have an offset temperature on the cores.

But who knows anymore.

I know, I'm sorry just messing(not Trolling):p I'm running an Antec 920 its good but not that good!:D

Sorry op didn't mean to hijack this thread.

Yep, bad wording on my behalf. When i wrote older I meant that my mobo is older and was surprised it supports IB.

op maybe a secondhand i7 2700k for your z68 board could be a cheap way forward.

They seem to be almost the same price as the 3770k both brand new and second hand unfortunately.

Decided to go for the 3770k. From what i've been reading it and the 8350 are almost on par for the second pass of encoding but the 3770k comes out further ahead as it's quicker on the first. Just have to see how it gets on with this mobo i guess.
 
@NZB, If you have the money, i7 3770k is a no brainer. Exception of course is a cheaper 2600/2700k if found. From what i read, 8530 "sort of" competes with the 2500k interms of encoding power lol.

With megui, one setting below placebo, 64bit x264, hyper-threading and OC (4.5ish) you can hit around 60fps (2nd pass) with dvd compression. So 2-3hrs aprox total. Almost real time encoding @ high level of transparency for standard def stuff.
