GeForce RTX 5090 Graphics / Video Cards

For most gamers, the honest answer is no. In native rasterisation the RTX 5090 is roughly 33 per cent faster than the RTX 4090 across a broad range of titles, which is a meaningful but not transformative improvement if you are already gaming at 4K. Where the upgrade becomes more compelling is DLSS 4 Multi Frame Generation, which is exclusive to Blackwell hardware. In titles that support MFG and where you are pushing for maximum frame rates at 4K, the 5090 delivers a noticeably different experience. For content creators working in DaVinci Resolve or Blender, improvements of 40 to 56 per cent over the 4090 are well documented. If you own a 4090 and primarily game at 1440p or lower, wait for the next generation.

NVIDIA officially recommends a minimum 1,000W PSU. In practice, most builders recommend 1,200W if you are pairing the RTX 5090 with a high-end CPU such as a Ryzen 9 or Intel Core i9, which can draw 150W to 250W under sustained load. The 5090 itself has a 575W TDP, a 28 per cent increase over the RTX 4090. The card uses a 16-pin PCIe 5.0 power connector, so check that your PSU has a native 16-pin cable. Do not use cheap adapters with this card. If you are unsure whether your current PSU is adequate, contact our team before ordering and we will give you a straight answer.

DLSS 4 Multi Frame Generation is exclusive to RTX 50 series Blackwell hardware. Here is how it differs from previous generations:

• Standard rendering: the GPU renders every frame from scratch.
• DLSS Frame Generation (RTX 40 series): one rendered frame, one AI-generated frame. Output is roughly doubled.
• DLSS 4 Multi Frame Generation (RTX 50 series only): one rendered frame, up to three AI-generated frames. Output can be quadrupled.

Generated frames are not fully rendered frames, so input latency and base frame rate quality still matter. MFG works best when base performance is already above 60 FPS native. In well-supported titles at 4K, however, the improvement in perceived smoothness is real and goes well beyond what raw rasterisation numbers suggest.

The RTX 5090 is a legitimate professional tool. In Blender using OptiX acceleration it outperforms the RTX 4090 by around 40 per cent in render throughput. In DaVinci Resolve, GPU-accelerated improvements of 46 to 56 per cent have been measured in noise reduction and colour work. AI TOPS performance is rated at approximately 154 per cent higher than the 4090, which translates directly to faster local AI inference, image generation in tools like Stable Diffusion, and video synthesis. The 32GB VRAM is also enough to run large language models in the 13B to 30B parameter range locally without quantisation, with 1,792 GB/s bandwidth delivering fast token generation speeds.

The NVIDIA MSRP of AU$4,039 applies to the Founders Edition only. Aftermarket AIB models from ASUS, Gigabyte, MSI, and others are priced above this. The variation reflects the cooling solution (larger coolers run quieter and maintain lower temperatures under sustained load), factory overclock (some models ship with a higher boost clock), power delivery quality, and brand positioning. ASUS ROG Astral and Gigabyte AORUS Xtreme models sit at the premium end. MSI Ventus and Gigabyte Gaming OC cards sit closer to MSRP and deliver the same gaming performance for most users. If noise and peak thermals matter, the premium cooler is worth it. If you are primarily gaming, the performance difference between AIB tiers is negligible.

Most RTX 5090 AIB models will fit in a full-tower case without issue. Mid-towers are more case-specific. Before buying, check three measurements:

• Maximum GPU length inside the case (measure from the PCIe slot to the front panel or any HDD cages).
• Slot width clearance (many 5090 AIB cards occupy 3.5 to 4 expansion slots).
• 16-pin cable routing (the connector is stiff and may need clearance room depending on your case layout).

The NVIDIA Founders Edition is a two-slot design and more compact than most AIB options. If case space is tight, it is worth considering. Contact our team with your case model and we will confirm compatibility before you order.

Yes. The 32GB GDDR7 VRAM is the key advantage here. Most consumer GPUs top out at 16GB or 24GB, which limits which AI models can run at full precision locally. The RTX 5090 can handle models in the 13B to 30B parameter range without quantisation, and with quantisation it can load significantly larger models. The 1,792 GB/s memory bandwidth is 78 per cent higher than the RTX 4090, which matters directly for token generation speed when running tools like Ollama, LM Studio, or ComfyUI locally. If local AI inference, Stable Diffusion, or video synthesis are part of your workflow, the RTX 5090 is the most capable single consumer GPU available for that purpose.
