The Best GPU Upgrades for an Existing PC
Five cards chosen for drop-in upgrades, with the power supply, connector and case length each one needs listed up front.
By Alex Morgan, PC Hardware Editor
12 min read5 products evaluated

An upgrade has to fit a PC you already own. Before choosing, check your power supply's wattage and PCIe connectors, the gap in front of the card in your case, and whether your board has a PCIe x16 slot.
We compared connectors, recommended PSU and size from each listing and the chipmakers' guidance; we did not install these cards in test systems.

Biggest Upgrade1 of 5
GIGABYTE Radeon RX 9070 XT Gaming OC 16G
Gigabyte's RX 9070 XT Gaming OC pairs AMD's top RDNA 4 chip with 16GB of GDDR6 and a WINDFORCE cooler.
Best for
- PCs with a 750W or larger supply.
Skip if
- Its cooler thickness is not published, which rules it out if you need that number.
Why we like it
At the time of writing it cost about half as much as the RTX 5080 cards we researched, which makes it the strongest value in the upper tiers. It matches the ASUS Dual 9060 XT 16GB on video memory (16GB). No other pick in this guide offers an RX 9070 XT gpu; compare the MSI 4070 Ventus 3X E1, which has an RTX 4070 gpu.
It also offers server-grade thermal conductive gel and RGB lighting. No dimensions are published for the Gigabyte RX 9070 XT Gaming OC; get length and thickness from the maker's page first. Its power connector and recommended PSU are not published, so confirm both for the Gigabyte RX 9070 XT Gaming OC with the maker. On price it sat fourth of 5, between the cheaper MSI 4070 Ventus 3X E1 and the pricier ASUS Prime RTX 5070, at the time of writing.

Best NVIDIA Upgrade2 of 5
ASUS Prime GeForce RTX 5070 12GB OC
The ASUS Prime RTX 5070 is a 2.5-slot, SFF-Ready card with a quiet/performance BIOS switch.
Best for
- Mid-tower PCs with a modern PSU.
Skip if
- Price-first buyers should look at the ASRock RX 7600 Challenger Pro, which cost less when we checked.
Why we like it
Its 12GB of GDDR7 is enough for most games at 1440p, though less than the 16GB AMD cards here. On video memory it ties with the MSI 4070 Ventus 3X E1 at 12GB. You get an RTX 5070 gpu here, which sets it apart from the ASRock RX 7600 Challenger Pro and its an RX 7600 gpu.
No other pick in this guide offers GDDR7 memory; compare the MSI 4070 Ventus 3X E1, which has GDDR6 memory. It is the only pick here with a 2587MHz (OC mode) boost clock; the MSI 4070 Ventus 3X E1 has a 2520MHz boost clock instead. It also comes with dual-ball fan bearings and a phase-change GPU thermal pad.
The ASUS Prime RTX 5070 occupies 2.5 slots, but no length is published, so check the maker's spec page against your case. At our last price check it topped the group, with the Gigabyte RX 9070 XT Gaming OC the nearest cheaper option.

- We lined up five cards on GPU, video memory, memory and cooler thickness as the makers state them. These are research figures, not bench results: 2 of 5 picks leave out cooler thickness.
- What every pick has in common
- All 5, from the Gigabyte RX 9070 XT Gaming OC to the ASRock RX 7600 Challenger Pro, state GPU, video memory and memory.
- Where the specs have gaps
- The Gigabyte RX 9070 XT Gaming OC and the MSI 4070 Ventus 3X E1 give no cooler thickness; the Gigabyte RX 9070 XT Gaming OC gives no boost clock.
- Price range
- At our last check the picks ran from the ASRock RX 7600 Challenger Pro ($250 to $500) to the ASUS Prime RTX 5070 ($500 to $1000).
