Just a PSA for anyone looking to buy and/or tweak this card. I own the XFX Liquid Cooled variant of this with Samsung HBM2. I have done heaps of research and modified this card extensively for weeks on end. Hardware tweaking is my hobby and the Vega is extremely fun to mess with. As a preface to make it very clear as other users have said, THIS DOES NOT COMPETE AGAINST THE 1080 Ti, even when overclocked (unless it's a lucky Vulkan title, see World War Z). However, in most titles with current drivers (19.1+), this card is well above the GTX 1080. I can confirm this directly as I also own a Zotac 1080 AMP! Extreme that is overclocked to its limits (but still loses regularly to my Vega 64). It will certainly vary in some titles and resolutions, but across the board I typically have a 5-10 FPS advantage over the 1080 at a minimum, not including Vulkan. Please also note that the Vega 64 on the Liquid Cooled BIOS will always perform better (and has access to more power) than a standard reference or custom PCB variant (IE, Sapphire Nitro). You can flash the LC BIOS to almost any Vega, but I will not provide assistance or steps on that.

Moving forward, don't listen regarding the PSU requirements. While it will vary depending on hardware extensively, these cards will sip energy under load if you manage a good tweak template! First and foremost, know that Vega does NOT scale well with core clocks whatsoever, your only true interest should be in getting a high and stable HBM2 overclock with core coming in 2nd. The Vega is extremely easy to undervolt and benefits largely from it. The GPU has 7 power states and you're welcome to tune all 7, but it's extremely time consuming and you will have difficulty telling which state failed under load. If you're looking to overclock and undervolt, in my experience it's best when setting a locked, static min/max powerstate 7 clock while upping the voltage by 5mV each test (my current locked ceiling is 1667MHZ @1060mV with a real 3D load boost factor of 1600-1630MHz). With each addition of this tiny power increase you should notice a proportionate clock speed jump in 3D loads until efficiency finally plateaus for power needed vs clock speed (mine did at 1060mV). Every 5mV should add 4-6MHz on Vega's boost algorithm, this happens without adjusting the clock ceiling directly. Once you reach peak efficiency on wattage-per-clock and the card stops boosting itself, slowly raise your clock ceiling by 10MHz until it crashes. If it crashes, add another 5mV and proceed until it stabilizes. Make sure to monitor you power draw in 3D loads to ensure the card isn't suddenly sucking 30w+ more power from a 5mV bump, as this happened in my experience. Verify your clocks under 3D load because the desktop will not report real speeds. Oh, and drivers WILL affect your overclocks/undervolts, so be sure to keep multiple stable profiles for testing if you downgrade or upgrade. Please note that the memory voltage is the voltage floor. The HMB2 is hard set by the BIOS at 1.36V+ and is not modifiable. You are setting the voltage floor for the card's lowest possible curve and thus its overall stability (but be aware this voltage can still vary and dip below at times). Always make sure this is lower than your P7 voltage. Ultimately, Vega is a GPU you will play tug of war with quite frequently, but it will eventually pay off if you're patient (or enjoy the torture like myself).

Anyways, that long-winded tutorial of sorts aside, by doing this I have reached what I would consider some very impressive settings! You can attempt to copy and paste my tune, but each card is unique and your experience will vary.

Current overclock/undervolt-
Core: 1667MHz (Real boost clocks 1602-1629MHz)
Memory: 1145MHz
Voltage: 1060mV set, 967mV 3D load
Draw: 187w-200w avg, 231w peak (firestrike, metro, valley, furmark)
Voltage Floor: 950mV (HBM/Memory voltage)
Power Target: 242% (search for buildzoid's powerplay registry mod)
Temp: 44c avg, 48c peak, 69c hot spot peak

Turbo stock-
Core: 1747MHz (Real boost clocks 1739-1757)
Memory: 945MHz
Voltage: Auto, GPU-Z reads 1.2v+ under 3D load
Power Target: Off
Draw: 356w avg, 381w peak (firestrike, metro, valley, furmark)
Temp: 55c avg, 61c peak, 86c hot spot peak
--------------------------------
Valley Benchmark performance increase in %
Ultra Preset, 3440x1440P, 8xAA
Stock Turbo score: 1744
Overclock/Undervolt score: 1936
Average score up by 11%
Average FPS boosted by 11% - 41.7 FPS to 46.3 FPS
Min FPS boosted by 9.4% - 25.5 FPS to 27.9 FPS
Max FPS boosted by 11% - 81.5 FPS to 90.7 FPS

I grabbed a used version of this card off eBay over a year ago. During the mining craze. I as told it wasn't used for mining I have my doubts, however I have had absolutely no issues with the card. I paid 700 used, again mining craze, I also got 300 bucks for my 2 year old 390x at the time so it was a decent trade. I paid about that for my 390x new and had it for 2 years. This card is about double the performance. The LC cards are better cards they OC better and have Samsung memory which also OC better. I have been able to under-volt this card and it stable around 1600 Core and memory at 1100. It benchmarks higher than it does in turbo mode with those settings pulling about 210 watts compared to 370 ish in turbo. It runs pretty much every thing maxed out over 60fps or better in 1440p. Since I only play 1440 I'll hold onto for a while. But Navi is promising a lot for less if your in the market for a new card you might wait.

Side note I use an 850 EVGA G3 PSU.
Just my 2 cents

I added aftermarket liquid cooling to my $299 Vega 64 I snagged on Cyber Monday, best value ever. Just shy of 1080ti for half the cost
Just shy of 1080 (non-Ti)... right?

This will beat the 1080 I'm some games, lose in some others. It's close in averages. However it will beat the 1080ti in a few Vulkan titles. This card OCd is just a monster.

I had this card, I currently have a 2080 ti. The 2080 ti performs better but at a significant cost. Kinda wish I kept the Vega over spending more for a 2080 ti since I'm only doing 1440p gaming.

Been running this card with significant oc and its performing equally to my 2080 in some games (even non vulcan) for example Pubg is at 120fps all ultra on 2k.

Only downside is the monstrous power draw. Takes well over double the power of the 2080. Also, if your psu cant push the power, it can be unstable. Any slight lack of power and hello crash.

Cant speak to quality of the refurbished ones, but with a good one OCed paired with a quality 800+watt psu it is capable of some serious performance.

Would a 850w PSU be ok here?

decent product at a great price, but let's put in some facts: with liquid cool, this thing is on 1080 level (and definitely cheaper and quieter than 1080). it is NOT approaching 1080TI no matter how you look at it, nor should it at this price.
the 32 game benchmark shows the regular vega 64 is about 5% slower than 1080 and liquid cooled is about 4% faster (but still 18% slower than 1080 TI with about 25% more power consumption)

Agreed, this thing overclocked is worse than Fermi housefire memes. That said you can undervolt it with a bit of work.
Id go refurb 1080 for cheaper, Zotac has been selling them for $319 recently.

Course this would be good for an AMD build and if you like to tinker, but will take up a lot of room in your case with the water cooler.

Not sure if i am going to agree with your "just shy." Maybe a certain game at a certain resolution.
