If you’re looking for a strong GPU that can push high frame rates in 1440p across a number of different titles, and don’t want to spend thousands in doing so, then the RTX 4080 Super should be high on your list of considerations. One of the latest arrivals into NVIDIA’s 4000 series GPU lineup, the RTX 4080 Super supersedes the 4080, offering up better value for money and a perfect uplift to match
It doesn’t quite worry the performance delivered by the RTX 4090 or RX 7900 XTX, but it does provide solid performance for a price point that is relatively void of solid choices. The 4080 Super offers up 16 GB of GDDR6X VRAM, a 256-bit memory bus, and 10,240 cuda cores, allowing it to deliver excellent performance in 4K & 1440p.
If you’re looking to build a gaming PC around the Samung Odyssey G9 and want to ensure you don’t encounter FPS problems when playing more demanding games, then a GPU like the 4080 Super is a great place to start.

If you’re looking for something a little more budget-friendly for your Samsung Odyssey G9 PC setup, then the RTX 4070 Ti Super is a fine choice indeed. It might not push the same frame rates as some of the other GPUs in this guide, but it does a good enough job without breaking you financially for years to come.
All jokes aside, the RTX 4070 Ti Super is a great GPU that offers a decent generational uplift over the 3070 Ti and the superseded 4070 Ti. In our tests, we saw decent performance in games like CS2 and Doom Eternal, with framerates exceeding 300 respectively. For more demanding titles like Cyberpunk 2077, the card still manages to product 100 FPS, respectively.
Overall, the RTX 4070 TI Super is a fine alternative to some of the more expensive options above, offering up good performance at a price point that is considered excellent value for money right now.
Samsung Odyssey G9 specifications
It is a super ultrawide gaming display, the Samsung Odyssey G9. It has a huge 49-inch screen with a 32:9 aspect ratio and a resolution of 5120×1440, which is comparable to aligning two 27-inch 1440p displays side by side.
Additionally, it has a tough 1000R curved screen that forces the edges into your range of vision. With a quick 240Hz refresh rate, native FreeSync variable refresh rate (VRR) support, and G-SYNC compatibility to lessen screen tearing, it is perfect for gaming. It lacks Mini LED backlighting, unlike the Samsung Odyssey Neo G9 model that finally took its place, although it still has a VA panel with edge-lit local dimming.
The G9 is a dedicated gaming display with all the vital gaming specifications you’d expect from a top-tier model. It is Nvidia G-Sync compliant and has a refresh rate of up to 240 Hz and a response time of 1 ms.
You may still buy cards at MSRP at Best Buy and MicroCenter as well as via internet vendors. It’s challenging to even get yourself in a line for one, check out before someone else makes a purchase, or enter a store early enough to take one off the shelf.
