I have relatively old PC bought back in 2011, PSU - Seasonic X-760 760W and motherboard Asus P8Z68-V PRO/GEN3 (which has pcie 2.0…), so both can be an issue. Though my 1060 6gb works just fine…
Nevertheless, this was a push for a new pc build which hopefully will be ready soon:)
I never had Radeon before and this is totally new experience. While nvidia you just “plug and play”, with radeon vii a lot of tweaking needs to be done.
