    all i hear is bad things and they seem way more expensive.

    OCUK have 6800Xts for £680ish at the moment. I had to choose between keeping my 3090 FE and 6800XT last year. I chose the 6800XT ( since swapped for a 6900XT and not worth it ) because it performed better in the games I play.

    holy crap! THANK YOU mate! I usually use scan as ocuk always seem to rip people off and be more than scan (for example my entire build was like £80 more? for the same or less model parts from same brand!) and scan for some reason have the 6800xt's up for £869.99 and up!

    that's fine I won't be buying it for awile yet mate, just getting a plan together! this means I save £189.99 on my build and can now double my m.2 size or get a second drive. I wanted originally a dual boot hackintosh/gaming rig so this means I get myself a mac pro killer at the same time now as they don't support nvidia 3XXX etc... amazing!

    after looking at it again I think I'll stick to the 3080 and not do a hackintosh I don't 'NEED' a second mac tbf and it'd be just wasting the power I could be using for gaming. 1tb should be enough for 5+ triple A titles installed right? don't want to end up regretting not waiting another month to get a 2tb version as I want to avoid adding a second m.2 and it running in pci-e 3x vs the 4.0 main slot :\

    Because I am an incredibly interesting guy here is my wall power (what you're being charged for) playing pubg on max settings with a PBO'd 5950x and 3080Ti, does not include monitor power as that is on a different UPS socket. Obviously numbers fluctuate up and down but to give an general idea.

    Lower res means GPU can run harder and as such uses more CPU in this title, other games react differently.

    upload_2022-6-11_11-54-3.png

    Unlimited 1440p is about 300-330fps
    Unlimited 4k is about 150-170fps

    This is out in the open obviously indoors etc, uncapped, it goes nuts :D

    Good info that Sandys. Have you undervolted your GPU? I put a 3080 in my sons system along with a 5900X and have managed to keep it in check with a single 360 rad by under volting

    It runs an undervolt but not targeted to save power more so to optimise it under water and to give me higher clocks and more frames within the 400w card limit, so it typically runs >2Ghz clocks and RAM with an extra Ghz or so.

    I could save more power if I set that as a goal in reality the machine is so strong it'd put in good frames in that title with much less CPU and GPU setting.

    The easiest way to reduce GPU power without affecting stability is to do either:
    - lower FPS limiter
    - reduce GPU power slider down

    I still think 30 FPS is good enough for slower SP games. I completed Cyberpunk at around 50 FPS. 60-100 is what I typically aim for in SP games. I personally can't say I notice much difference between 70 and 144 Hz/FPS in SP games I play. Below 60 it feels sluggish initially, but feels fine once get used to it.

    I remember maxing out Crysis with 25-30 FPS, slightly unplayable but still got through the whole game like that :hehe:

    so is that literally an option I set in the nvidia control panel? it's been YEARS (2008) since I've built anything that isn't mac haha!

    Well, yes and no.

    For FPS limit, it's set here, in nvidia control panel: (I'm sure AMD have a similar setting)
    upload_2022-6-13_15-15-9.png

    For GPU power limiter, if you want to hard cap GPU power consumption instead of based on FPS performance, it's set in a program called "MSI Afterbuner". Back in ~2008, it would have been set using Rivatuner, it was THE tool to use if you had attempted overclocking the GPU. Afterbuner is the modern version of Rivatuner.

    Undervolt is also done by Afterbuner. That is a practice of setting a lower voltage at same frequency to reduce power consumption but doesn't reduce performance. However, undervolt may introduce instability, whereas the 2 above methods reduce power consumption and performance.

    for me it's about building something ridiculous that'll last me atleast 5 years at atleast 1440p with dlss in the future when it requires dlss to gain 60+ in SP games. so I'm spending the extra now to future proof it versus just having something that'll play games fine for a couple years then require replacing parts. Hope that makes sense?

    So do I use both or 1 or the other? I remember hearing about after burner. so it works for whatever brand I'm guessing? I'm getting an msi anyway (providing the price stays the same and there's stock in oct-nov when I buy it all lol) for ref I'll be buying a lg 32gp850-b so 180hz with the overclock over the 165hz stock. so would lock it at 60-100 fps for SP games and then 180 for MP.

    For us Commie Linux types, the same functionality is available at the terminal in the drivers or graphically via GreenWithEnvy.

    I'll eat my hat if the 6800/6900XT doesn't outperform a 3080 in 4-5 years. AMD has FSR to counter DLSS it's also open to all so I think I'll be more widely adopted in the long run. It even works on Nvidia cards!

    * I don't actually have a hat and if I did I wouldn't eat it.

    6x00 has typically outperformed the 30x0, so get chomping, less so at higher res but certainly at 1440p. Only weakness is ray racing but that isn't that good on Nvidia yet.

    Wouldn't bank on it getting any faster, they never do.

    If gsync / freesync is anything to go by, then fsr will indeed probably out live dlss snd xess.

    i've not seen any games bar like ass creed and something else (neither that i'd play) that beat the 3080... everything i'd play seems to be slaughtered by the 3080... hmm.

    Slaughtered only if you play with RT, anything else they are hard to separate.

    Card hierarchy at 1440p over 18 games, if you play at lower resolution then 6x00 all the way as Nvidia driver overhead is too high.

    Basically there's not a lot in it but there is more scope for OC'ing the 6x00 if under water as I am, so it was really a flip of coin thing for me, I went Nvidia drawn in but the internets gushing of Raytracing and DLSS but that is rubbish, give me maximum normal rendering anytime.

    won't be watercooling mate, and I want Ray tracing. so I guess I'll stick with the 3080
