Buying Guide
The Fastest Gaming GPUs You Can Buy
The top chip from each recent flagship tier, ranked by where NVIDIA and AMD position them, with the power and size each one demands.
By The PC Journal editorial team
12 min read5 products evaluated
Speed rankings shift with each game, so we ordered these cards by chip tier as NVIDIA and AMD position them, not by our own frame counts. The RTX 5090 sits at the top, followed by the RTX 4090 and RTX 5080.
We compared VRAM, memory type, boost clock and recommended power from each listing; we did not benchmark these cards.

Top Chip Available1 of 5
ASUS TUF Gaming GeForce RTX 5090 on Amazon (opens in a new tab)
The ASUS TUF RTX 5090 is in a class of its own with 32GB of GDDR7 and 21,760 CUDA cores.
Best for
- The highest tier NVIDIA sells.
Skip if
- Price-first buyers should look at the ASRock 7900 XTX Phantom Gaming, which cost less when we checked.
Why we like it
At the time of writing it cost several times more than the other cards here, so it only makes sense when nothing slower will do. Nothing else here matches its 32GB video memory; the ROG Strix 4090 comes closest at 24GB. No other pick in this guide offers an RTX 5090 gpu; compare the ASUS TUF 4080 Super, which has an RTX 4080 Super gpu.
It shares GDDR7 memory with the ASUS TUF RTX 5080; the ASRock 7900 XTX Phantom Gaming goes with GDDR6 memory. You also get a 512-bit memory bus at 28Gbps and a GPU holder in the box. It was the highest-priced of the 5 picks at the time of writing, so the case for it rests on what it adds over the ROG Strix 4090 and the rest. The maker doesn't give its recommended power supply; if that figure matters, the ASRock 7900 XTX Phantom Gaming offers 800W.
Key dimensions & specs
- GPU: RTX 5090
- VRAM: 32GB
- Memory: GDDR7
- Outputs: 3 x DisplayPort 2.1b, 2 x HDMI 2.1b

ASUS's ROG Strix 4090 uses a vapor chamber with a milled heatspreader and enlarged Axial-tech fans.
Best for
- Buyers who find a 4090 in stock.
Skip if
- Price-first buyers should look at the ASRock 7900 XTX Phantom Gaming, which cost less when we checked.
Why we like it

It shares GDDR6X memory with the ASUS TUF 4080 Super; the ASRock 7900 XTX Phantom Gaming goes with GDDR6 memory. No dimensions are published for the ROG Strix 4090; get length and thickness from the maker's page first. Its power connector and recommended PSU are not published, so confirm both for the ROG Strix 4090 with the maker.
Its price falls between the ASUS TUF 4080 Super and the ASUS TUF RTX 5090, based on our last check. Buyers who need a confirmed recommended power supply should compare it with the ASRock 7900 XTX Phantom Gaming, which offers 800W.

How We Chose
Each pick was assessed across 4 criteria weighted for real-world use.
- Cooling and extras
- We checked cooler design, fan-stop modes, dual BIOS, support brackets and display outputs.
- Price tier
- We grouped picks by price at the time of writing rather than by listed clock speed.
- Power
- We noted the power connector and recommended power supply where listed.
- GPU and memory
- We compared the chip, video memory capacity and memory type stated in each listing.
What to Look For
Key buying criteria so you get the right fit the first time.
Compare upscaling and encoders
NVIDIA cards support DLSS, AMD cards FSR and Intel cards XeSS. Each game supports a different mix, so check the titles you play.
Streamers should also compare hardware video encoders.
Plan the power connector and PSU
Cards use one or two 8-pin PCIe plugs or a single 16-pin 12V-2x6 plug. Confirm your power supply has the right cables and meets the maker's recommended wattage.
Count the display outputs
Most cards offer three DisplayPort outputs and one HDMI, but some swap that balance. Check that the ports match your monitors, TV or VR headset.
Treat 8GB of VRAM as the floor
Some recent games already push past 8GB at high texture settings. Cards with 12GB or 16GB give more room, especially at 1440p and above.
Two versions of the same chip can differ only in memory; check the capacity in the exact model name.
Cooler size affects noise
Larger triple-fan coolers usually run quieter under load than compact dual-fan designs. A 0dB mode stops the fans at light load.
Match the card to your monitor
Resolution and refresh rate decide how much GPU you need. A 1080p screen at 144Hz asks far less than 1440p at 165Hz or 4K.
Buy for the monitor you use now or will buy soon, not for a resolution you may never run.

Frequently Asked Questions
How big a power supply do I need?
Use the maker's recommendation for your exact card, then add headroom if you run a high-power CPU. Also check the connectors, not just the wattage.
Will a PCIe 5.0 card work in a PCIe 4.0 or 3.0 slot?
Yes, the interface is backward compatible. Cards with a narrow x8 link can lose some performance on PCIe 3.0 boards.
Will my CPU hold the card back?
It depends on resolution and the games you play. At 1080p and high refresh rates the CPU matters more; at 4K the GPU sets the limit.
Should I choose AMD or NVIDIA?
Compare price and memory at your budget first, then features such as DLSS or FSR support in your games and hardware encoding if you stream.
Do I need a GPU support bracket?
Long, heavy cards can sag and stress the slot. Some come with a support stand or bracket; otherwise one is inexpensive to add.
Is an 8GB graphics card still enough?
For 1080p with tuned texture settings, often yes. For 1440p or high textures in new games, 12GB or 16GB is safer.
Bottom Line
The ASUS TUF RTX 5090 is the fastest chip on sale, with 32GB of VRAM. The ROG Strix RTX 4090 follows, the TUF RTX 5080 and TUF RTX 4080 Super cost less, and the ASRock RX 7900 XTX Phantom Gaming is AMD's top card.
