$80 extra and 30% more power consumption for 5% more performance?
You can take a $399 variant and get a similar overclock for free. Sure, there's more headroom in the Nitro+ SE but it already uses 285W just at factory clocks!
If you have the extra $480 you could just pick up a 2070 Super instead which is faster, uses far less power, and has hardware raytracing support. Newegg US has a Gigabyte triple-fan factory overclocked 2070S for $468 right now, $448 if you successfully apply the $20 rebate card. Yeah, it's a special offer but that's because the 2070Shas been out for 6 months already and you can always find at least one 2070S model for under MSRP, compared to this SE model that has just arrived and won't likely get discounts until the unsold stock has aged a bit on store shelves.
If you want a Navi card, buy a base-price one and undervolt it as far as you can go. You can expect to shave 20% off the power draw, heat, and fan noise without losing performance based on general forum reports. My own 5700XT is down by 25% power draw and it's only a reference model (actually, I just remembered I'm cheating because I capped the boost clock at 1850Mhz which is the average game clock, but that probably costs me a couple of percent in performance).
