I'd never heard of them and I'd be lying if I said they didn't look sketch. Like really, really... really sketch. I mean butthole puckered from the time of purchase to it successfully passing several tests including Fur Mark, CineBench, OCCT, HWINFO64, and AIDA64. 13+ hours of testing later, we got action. Butthole relaxed. professional review in 3, 2, 1... Sapphire Pulse RX 9070 16GB purchased from Nimbus Cyber Tech for $650. Nimbus disclosed the card as overstock/open-box, answered my questions before purchase, allowed installation/testing without affecting the return option, and shipped promptly. The card arrived as the correct model and passed OCCT GPU/VRAM/3D, 20+ minutes of FurMark with zero reported artifacts, full GPU load in gaming, and full-system stress testing with no recurring crashes, black screens, driver timeouts or WHEA errors. Packaging was OEM-style rather than full retail, and the exact prior history of the card is unknown, but this transaction worked out well. Product recommended; seller recommended based on this transaction.

GPU didn't take too long to arrive, everything seems to be working well, but didn't come sealed in a branded box, just inside a big antistatic bag, and one half of the radiator blades had hard to remove dust, strange, but no markers on PCIe or the important spots
