Is the ASUS ROG Strix RTX 3090 OC right for you?
If you find a used ROG Strix 3090 at a meaningful discount and need 24GB VRAM for Blender, 3D work, or video editing, the premium ROG Strix cooling and build remain genuine selling points.
If you're a pure gamer shopping at full price, modern RTX 5070 Ti or RX 9070 XT cards deliver better gaming with DLSS 4 features and current driver support at often-lower prices.
Before you buy
Only at a clear used discount and only if you need the 24GB VRAM. For pure gamers, modern RTX 5070 Ti or RX 9070 XT cards offer better gaming with DLSS 4 features at often-lower prices.
Similar 1440p gaming performance, with the 4070 SUPER winning in DLSS 3 Frame Generation support and current driver optimisation. The 3090 wins on VRAM at 24GB versus 12GB.
Nvidia recommends 750W as a minimum, but 850W is more realistic for sustained operation. With a power-hungry CPU like a Core i9 or Ryzen 9, step up to 1000W for transient spike headroom.
Yes, the 24GB VRAM is genuinely useful for Blender renders and 3D work, especially compared to modern 16GB cards. Used 3090s remain a sensible budget creator pick for VRAM-bound workloads.
