6700XT in MSI B450 Tomahawk Max

Hi all,

Will the 6700XT work fine in the MSI B450 mobo? The card is PCIe 4 whereas the board only has PCI-E 3. Doing some digging, the card does seem to be PCIe backwards compatible so I imagine it will work but my question is whether this will impact its performance at all?

Thanks

ive had the 6700xt in a old 2014 comp running z77 d3h and was ok after a bios update tho coulda been the other ram i added at the time why it didnt boot up, left the ram out put the latest bios on then worked and worked fine since, tho its in new pc now, put in a old 780ti in the old comp now. Tho a latest windows update causes it not to work so had to remove that update and pause updates.
 
Thank you for your replies.

One other quick one. I can't afford to upgrade my CPU too, so that'll be hopefully early next year. I'm currently running a Ryzen 5 3600X. Do you think that'll bottleneck any potential gains i'd be getting by replacing my GPU and so I may as well wait to upgrade both the CPU and GPU together in 6 months or so, or is it worth going from the 5700XT to the 6700XT now and then do the CPU later as per my original plan?
 
It will depend on the game and your resolution/settings, but I wouldn't be that worried about it (HUB have a couple of relevant videos, here and here). You can always ramp the detail up to push the bottleneck toward the GPU.

I do have to say though, a 6700 XT is only a mild upgrade and not something I'd personally bother with. Some videos:

Thanks for the reply.

I won't be in a position to get anything more expensive than that in reality any time in the next couple of years. So my thinking was the 6700XT will get me through the next 2-3 years (with a new CPU hopefully in 6 months) rather than relying on the 5700XT and its lower 8GB VRAM, and then look in to getting a whole new rig at that point.
 
Gpus are backwards compatible with the pcie lanes. The gen 4 will work with gen 3. If it doesn't all you have to do is go into the bios and change it from auto to gen 3.

SAM will really help you in cpu-limited situations, and when you get a 5800X3D you'll get a nice big boost :)

Yes that's the CPU i'm planning to get. I believe it'll work with my board if I sort the BIOS out. I'll have to post about that nearer the time as it's not something I have any experience with

You may as well try upgrading the BIOS now. Certainly if you have not done it since getting the MB. I am sure there have been AGESA improvements that will benefit you
 
AMD gpus will have less bottleneck with weaker CPUs than Nvidia cards so I don’t think it’ll be to bad and for 1440p+ I probably wouldn’t even bother upgrading the cpu at all, that said I’d still try and find the extra for a 6800 which can be had for around £400 and will perform similar to a £600 4070
