Is the RTX 3090 still worth buying in 2026?

Only if you need 24 GB of VRAM for AI or rendering work. For gaming, newer cards are faster and cheaper. At $1,699 it is hard to justify.

How does it compare with the RTX 4090?

The RTX 4090 is substantially faster in games and ray tracing and uses less power for the performance. The 3090's advantage is its lower price on the used market, not at this new price.

What power supply does it need?

Plan for an 850 W or higher quality PSU with two 8-pin PCIe cables. Gigabyte recommends at least 750 W.

Will it fit in my case?

The card is 13 inches long and about 2.5 slots thick. Measure your case's GPU clearance before ordering.

The card itself, usually with a quick-start guide. Cables and support brackets vary by seller, so confirm with the store.

Our take on the Gigabyte GeForce RTX 3090 GAMING OC 24G Graphics Card

The Gigabyte GeForce RTX 3090 Gaming OC 24G is an Ampere-generation flagship graphics card with 24 GB of GDDR6, aimed at 4K gaming and heavy GPU compute work. It uses Gigabyte's triple-fan Windforce cooler with a metal backplate and needs two 8-pin power connectors. At 13 inches long it is a large card, so check case clearance before buying. The best new price is $1,699.00 at neweggbusiness.com as of November 4, 2026, well above what this card sold for when it was current, so it is poor value against newer cards at that price.
