So I have an HD6XX/HD650 and looking to also try other cans in the future (maybe even HD800's as an endgame set) but the Mixamp of course was never really made to properly power the HD650 so I'm looking to get a upgrade. The reason I use the Mixamp is its separate sources for game & chat, and game/voice mix dial making it very easy cut out the voice chatter if I need to focus on something. Most dac/amp combos don't focus gaming features of course so options are limited, looking around looks like there is the SoundBlaster X3, X4 and GC7 but not a lot else. There's also the Schitt Hel 2 and Mayflower ARC 2 but looks like they just have a mic input and don't the separate sources for game & chat nor any mix ability so I'm wondering if there is any other alternatives out there.

For stills (aside from fast tracking for sports) Panny's Contrast Detect/DFD AF should be fine. For video though AF wobbles in and out of focus as it tracks a subject and can be distracting but if you got camera man that can handle manual focus then you should be fine.

I third(?) the A7lll, you already have one and lenses to go with it so it makes a lot of sense, between the lens selection, image/video quality, great AF for both stills and video, competitive price and other handy features like Dual card slots for photo and video backup its one of the most well rounded bodies for the price. Its not perfect though, the physical ergonomics and menu system could use some work and it has no 10bit recording of any kind for video. If your business get by with 8bit recording & the bodies ergo and menu layout go for the A7lll. If you need 10bit recording the Z6 from Nikon is worth a look as it can do 10bit via HDMI (and soon RAW recording over HDMI) and with the FTZ adapter you have ample glass selection and the body has been on sale multiple times this year for less the the A7lll

Is this for you or someone else? Is its for someone else are they are new to photography with a dedicated camera? If so Canon's M series lineup like the M100 would be great as their menu layout and generally excellent touch interface help keep frustrations to a minimum for beginners. If they are willing to put up with any UI on a camera however I would go with the Fuji as Fuji is the only 1st party company that actually cares about making a wide range of good lenses for APS-C sensors. If you want good glass from likes of Canon, Nikon or Sony for the most part you need to buy their lenses for full frame sensors which are heavier, bulkier, and more expensive. And unless you shoot sports/action, a better lens will give you generally better results then a fancier body.

How much more performance would I gain if I go from CL 17 to CL 16 or even 15 @ DDR4-3600? Hard to find any CL 16 or lower 16GB Dimms locally in Canada.

Since you already have EF glass makes sense to stay with Canon and EOS RP or the 6D MK2 are the best value for full frame which are great what you want to shoot. If you are willing to switch brands and sell your current lenses The D750 is excellent camera and is still Nikon's price to performance/value FF body for stills. Whatever you get though you will want good glass to go with it. The 50 & 85 F1.8 would be great for portraits and maybe some street shooting on a budget with the D750 or Canon 6D MK2. With the 6DMK2 though keep in mind EF-S glass is not physically compatible with it or any Canon FF DSLR but at least for stills you won't want to use it anyway. If you have a bigger budget the A7lll and the Tamron 28-75 F2.8 (if you can find it in stock lol) is also worth considering. Keep in mind though Sony's glass is usually more expensive compared to Canon or Nikon's DSLR glass, the current Mk3 A7/A9 Bodies might be too small and compact for some users and the bodies are not as weather sealed as the DSLR's. But in most cases if you take common sense precautions like keeping the port covers closed and hotshoe covered when its wet outside most prosumer bodies will do just fine in most conditions (outside of heavy downpour). Tamron and Sigma have value priced glass for Sony E mount (like the 28-75 F2.8, Sigma's Art primes and Tamron's upcoming 17-28 F2.8). Also the small size and electronic/silent shutter of the A7lll & most mirrorless cameras can help you blend in more and possibly get more candid street pictures, The A7lll and most current mirrorless bodies is also USB chargeable and some models can be powered over USB. Also more mirrorless bodies offer In Body Sensor Stabilization with help's with handheld shots and video regardless of lens For portraits most mirrorless bodies offer or will offer Eye AF which can help speed up the workflow while shooting and allows the shooter to focus on composition, lighting, etc while the eye is kept in focus by the camera automatically even while the subject moves around the frame. Whatever you decide to upgrade to, if you have access to a local camera store try renting the body and a lens and get some hands on time with the gear to make sure the controls, ergonomics and UI works for you before pulling the trigger.

As @TH Gamer mentioned your skill and experience as a photographer matters more then the gear. Almost any of the major brands will be able to get good results from what you are looking to shoot. But since there are so many brands and choices for cameras, if you have access to a camera store or business that does rentals try renting out a body and lens for a shoot and see how the ergonomics of the body and the layout of the menus and buttons work for you. As for the 2 models you mentioned the Image & video quality will be the same, the only differences a back control dial, a top LCD screen, and a mostly superfluous HDR video mode on the 760D so unless those features matter get the 750D and put the extra savings towards good glass.

Are most of your lenses EF-S (Crop/APS-C) or EF (Full Frame) glass ? If their mostly EF-S glass then the 6D MK ll is pretty much "no go" as Canon's FF DSLR's are not compatible with EF-S lenses. For that reason I'm also going to say get the EOS-RP with the EF to RF adapter (which for now is still bundled in for free at some stores) and your EF/EF-S lenses will all work great and its Canon's most affordable FF body to date.

What kind of lenses do you have ? EF-S (Crop Lenses) or mostly EF (Full Frame) glass? If you have mostly EF-S glass then the 6D MKll is pretty much a no go as Canon's FF DSLR's are not compatible with their EF-S lenses. Also what kind of Photography do you do right now? A lot portraits and landscapes or do you like to take advantage of the 80D's 7FPS and pretty good tracking for action and wildlife? If you don't do action/wildlife then save up for the EOS-R w/ its 30 MP sensor as its one of the 3 Canon Bodies that has an actually noticeable increase in resolution over the 80D and the cheapest @ 2300 USD + with the EF-RF adapter + you can still use EF-S glass something Canon's FF DSLR's can't do.

Based on that I would go with the one of the Canon Camera's with their Dual Pixel AF like the Rebel SL2/200D or M50, combined with the flippy touch screen and Canon's generally easy to use menu and interface you can tap on your face on the touch screen and it will follow you around the frame without any further interaction, and the flip screen will allow you to see what is being recorded while you are recording.

No idea but CES would be a logical time for Acer to give more details

The Acer Predator Z271 is 144hz, 1080p and its got a VA panel if you are looking for better colors and contrast then TN https://www.amazon.com/Acer-Predator-Z271-bmiphz-1920x1080/dp/B01I0NF8RI?th=1

My Ticket out of the 1080p/60hz stone age has arrived in the form of the ROG Swift PG279Q Also got a ModMic 5 for Christmas so I can now use my HD6xx as a headset and retire My Astro A40's

The HAF-932. Great cooling, built like a tank and it came with casters which for moving a 60lb rig with a full water cooling loop is a godsend (why don't others major case makers offer caster support?!?!). A 2nd place would go to the Caselabs S8. All Aluminium and American Built, lightweight with caster support and the horizontal mobo tray keeps heavy video cards sag free.

750D. More room for cable management and hardware then the 600T, Modual HDD Cages, dedicated SSD cages, super simple magnetic top dust filter and pretty good water cooling support. Unless you don't like the look or must have latched on side panels the 750D is a no brainier. Just add a dust filter for the bottom fan mounts if you plan to use them though.
