I could sell it and upgrade to a 4770K  | ||

There was a few batches of 3570k doing like 4.5ghz on 1.05v, like 5.2 maybe even higher without custom water, but in the end, if you consider haswell to be 15% faster with x264.. you only need ~4.52ghz to match it, so in the end it's not even that special any more. I'm not sure on actual sandy bridge - ivy bridge - haswell encoder performance, hard to find good data - everybody uninformed is using x264 benchmark 5.0.1 with the default encoder from mid 2012 without any of the haswell improvements or avx2 support etc You could sell it, to be honest i'd buy boss-level cooling, have some fun with it, wait for a bomb to drop like 6 core intel on mainstream socket (skylake 6-core, ddr4 2015 could be cool if it happens) that'll blow the roof off instead of making an upgrade that's likely somewhat incremental, if potentially big | ||

EDIT: Yeah, I'm more inclined to wait for a while longer. My H100i has my temps at about 56 degrees across all cores and that's under full load Prime95 | ||

I encoded for about 5-10 minutes w/ 1920x1080, 60fps veryfast setup in OBS - my peak temp on hottest core was 67c on air, with HT on - so it's not exactly a problem. It's harder to run dangerous levels of voltage, but i5 is hardly limited - i7 is more of a worry being like 12c hotter under threaded loads, but it's still ok, you just have to delid or have great cooling to run degradation-level voltages Given that to match a 2500k @4.5ghz - you'd only have to be at about 3.8ghz on Haswell for this type of load - i could use below 1.0vcore, my power consumption and temperatures would be very very low lets avoid turning this into SB vs HW thread though :D | ||

Having read probably 20 thousand posts in haswell overclocking threads, the issues are greatly exaggerated, largely by people who don't know how to use the chips I encoded for about 5-10 minutes w/ 1920x1080, 60fps veryfast setup in OBS - my peak temp on hottest core was 67c on air, with HT on - so it's not exactly a problem.

I'm just pleased that my upload speed is good now, went from 1.86Mb upload to almost 13Mb :D But the main issue for me is whether to stream the likes of LoL and SC2 in either 1080 30fps or 720 60fps. Which would be better do you think? A lot of people says 1080 45FPS is good as well but not quite sure on the limits of my system | ||

1080p30 vs 720p60 is preference, 1080p48 is probably just better if you can throw max twitch bitrate at it. I would on a pushed 4770k, dunno about 2500k (if your temps are in the 40's encoding.. why don't you OC further? Surely you bought h100i instead of an air cooler at a fifth to a third of the price for a reason :D) My preference would be the native resolution, probably. For a game like an FPS, then framerate>all and 540p@120fps over twitch would be pretty lovely to have, but nobody will stream for a niche market | ||

A lot of people say to not go over 1.4v to run an OC 24/7, so I could probably get to something like 4.8 / 4.9, maybe even more, but I'm not even sure it'd be worth it. The only games I'd probably stream are LoL and SC2. | ||

Got the latest version from this thread: https://obsproject.com/forum/viewtopic.php?f=11&t=6714 Anyone have any ideas? I can't imagine what I'm doing wrong but clearly I'm being a moron. | ||

Any ideas what the craic could be? Had a look, made a second profile as well, restarted OBS and my PC as well. Also somewhat related, could anyone recommend a good microphone? Possibly looking to do other audio content, maybe podcasting in the future so something of high quality. | ||

Are you in fullscreen in sc2 if so preview screen is black while alt tabbed to the preview screen I believe. And here's a microphone for you that's very good: http://www.amazon.co.uk/Blue-Microphones-Bidirectional-Omnidirectional-Microphone/dp/B002VA464S/ | ||

Cheers for the mic recommendation, was actually the one I had in my brain I remembered seeing it ages ago and then forgetting the name of the product. Much obliged! | ||

i5-3570k no overclock (3.6ghz with default boost) hyper 212 evo but can get a h100i and oc if ever needed gtx 670 1gb/s pipe tldr: should i stick with 1080p 60fps 3500 bitrate, lower it to 48fps because the extra 12fps does nothing but work my cpu harder, or try raising the bitrate even higher for smoother streaming? twitch.tv/fortunefighting for reference, if there's on screen "current song" its obs, if not shadowplay | ||

Edit: also a question, why 48fps everywhere? sure it's 3fps higher than 45 but it's strange to speak of this for anything other than movies(24/48). | ||

48 = 4/5 of 60 50 = 5/6 of 60 ^limitations of most screens (60hz as opposed to infinite, synced refresh rate) tldr: should i stick with 1080p 60fps 3500 bitrate, lower it to 48fps because the extra 12fps does nothing but work my cpu harder, or try raising the bitrate even higher for smoother streaming? IMO not worth going past ~48 for most stuff on 1080.. too bitrate starved. Dropping FPS from 60 to 48 gives you 1.25x as much bitrate for each frame, while meanwhile you were probably having trouble keeping FPS far enough above 60 anyway in sc2 (and reducing capture framerate, at least using game capture+x264, will increase performance) 1080p60 on stock 3570k sounds a little crazy I might make an x264 benchmark thread | ||

I'm wondering what's the highest FPS I can go whilst not suffering performance wise? | ||

You'll suffer regardless, as i measured from Game Capture + x264 - even though CPU never hit 50% average load (though i didn't affinity cores away from the game) there was >20% performance hit on raw average and minimum FPS - i'm not sure what effects come into play as CPU gets to a higher load, but i know averaging too high can result in spikes and very slight performance hangs if you're too highly loading CPU (i saw on my i7 950 @4ghz trying to encode high res at higher fps, when jolting camera around, but my current cpu is far, far more powerful) | ||
