I was not initially looking to buy a graphics card from this site, I was looking on ebay for this card and had gotten scammed by a seller posing as NCT. I sent an email to NCT and they were exceedingly quick to respond! After that whole ordeal, I ended up deciding to purchase the card from NCT as they had been so kind to me over our conversation.
After ordering the card, the delivery was exceedingly quick, and it arrived in fine condition, I did the swap that night, and after running some tests everything seems to be running flawlessly!
I will 100% be looking at this site again for future tech purchases. Again, amazing super fast customer/consumer support.
Thank you!
I was a little worried when I came onto this place and finding the 7900xtx in this condition and for the great price as well. There was a small delay in shipment due to weather, but needless to say there was great and quick communication the whole time to reassure me. After getting the GPU in I looked over it and it was in pristine condition. Later I installed it and spent time looking everything over and ran a few different stress and fan tests using the OCCT app. All came back with Zero errors and the gpu kept running like a champ.
It looks great in my current tower (Corsair 5000D Airflow Edition) and I look forward to moving it to my new tower
I will definitely recommend this site to my freinds for thier future upgrades.
Edit: I wanted to add a new photo of it in my new tower and setup. Looks epic and clean. Gaming sinc then has been a breeze at any setting for me.
I’m running the Sapphire Nitro+ RX 7900 XTX with a Ryzen 7 7800X3D, tuned to:
Voltage: 1085 mV
GPU Frequency: 2400–2800 MHz
VRAM: Locked at 2700 MHz
Power Limit: +15%
In 3DMark Time Spy (free version), the scores are:
Total: 27,373
Graphics: 33,809
CPU: 13,169
Thermals are well-managed with VRAM maxing at 80°C, hotspot around 73°C, and peak board power at 431W.
In gaming:
GTA V Enhanced Edition (with VisualV mod): Runs 4K High to Ultra settings, maintaining 85–105 FPS smoothly.
Red Dead Redemption 2 (Vulkan): Mostly Ultra at 4K, average FPS ~116, 99th percentile above 90 FPS.
The system is housed in a Lian Li Lancool III case with a Noctua NH-D15 CPU cooler (two 140mm fans). Case airflow includes three 140mm front intake fans and two 120mm Noctua reflux intake fans at the bottom for minimal added airflow. Exhaust consists of one 140mm rear-top and one 120mm top-rear fan. I may upgrade to three 140mm bottom intake and three 140mm top exhaust fans later, but current temperatures are excellent.
I'm really happy with the purchase. The GPU arrived well-packaged, included a peel-off
protective film, and came with the Sapphire branded support bracket.
Thank you, Nimbus!
I decided to give Nimbus Cyber Tech a try because they had a great deal on the 7900 XTX. Their communication was on point and everything was in perfect condition as described. They made sure that everything was up to standards and that I was satisfied with the order from start to end! Literally no complaints at all and I left very happy afterwards.
Definitely hoping to pick up a thing or two (maybe more who knows) down the line with them again!
Incredibly beautiful build. Thanks for sharing! Hope to get you the new series when they are available. 8]
