I'm still grateful to simply live in a world where a VR champ like the GeForce GTX 1080 exists, but if you want to get a bit more serious, you might want to look into MSI's Sea Hawk edition. Along with EVGA, ASUS, Gigabyte, Zotac, and a half-dozen other companies, MSI announced its own premium versions of Nvidia's hot new top-end graphics card today.
All these companies are looking to squeeze a bit more performance out of the card by combining superior cooling and a bit of overclocking to Nvidia's stock version — or at least putting some pretty fans and lights on top and competing on price. MSI has a good record of making a relatively quiet GeForce, and it teamed up with Corsair to introduce a liquid-cooled edition of the card. The card is overclocked to 1847MHz, compared to the 1080's regular boost speed of 1733MHz.
If you're really looking for the best possible 1080, you'll have to wait for the reviews. HotHardware already has a preliminary look at the EVGA Superclocked ACS 3.0 edition — it seems to be faster than Nvidia's Founder's Edition, but only marginally.
But if you want liquid cooling because, well, you like telling people your PC has a liquid-cooled top-end graphics card, MSI Sea Hawk looks like the primary game in town right now. No word yet on price, but this one probably won't be cheap.
