I was initially going to go for an msi b450 tomahawk but lots of people have been saying to avoid the msi and gigabyte boards and go for an asus but the asus ones are very expensive and i don't want to spend over £100 (UK).
Any MOBO suggestion or whether i should still go with the tomahawk?
A second thumbs up for the B450 Mortar here. I've been running my 1700 at 3.9G and the VRM stays cool even under heavy stress testing. I've tried to take it to 4.0G but the CPU won't stay cool even under a 240mm AIO. I can't blame the VRM: it stays cool and the voltage well controlled, the CPU's just not one of the 'golden samples' that will do 4 Gig at reasonable voltage. And other features it has makes it a great value: 2nd NVME, BIOS button that allows flashing a new BIOS even without a CPU or memory installed and others.
There is one technical beef with MSI's approach, though, that's valid. MSI doesn't offer offset voltage adjustment on their B450 boards including Tomahawk and Mortar (I can't say about X470 boards). Offset is very useful when overclocking using performance boost settings (PBO) with the 2600X and 2700X CPU's. But only the X models, the ones with XFR2 features, really need it even though some people prefer offset voltage adjustment to direct adjustment. That may be the source of it so consider if that's what you need when filtering the MSI hate you're hearing.
