Choose a gaming PC’s RAM, storage, and graphics card around the games you plan to play and the resolution, frame rate, and graphics settings you want—not a single universal parts list. Check each game’s current minimum and recommended requirements, then leave room for your other games and updates. System RAM, GPU video memory (VRAM), and storage solve different problems and should not be treated as interchangeable.

How much RAM do you need for gaming?

Use the requirements for your target games as a starting point. In the examples below, 16 GB is listed for several games, but S.T.A.L.K.E.R. 2 specifies 32 GB recommended for its stated high-settings, 1440p/60 FPS target. These figures describe the publishers’ listed targets, not a guarantee of identical performance on every PC.

Game System RAM listed Target context
FINAL FANTASY VII REBIRTH 16 GB minimum and recommended 1080p/30 FPS low minimum; 1080p/60 FPS medium recommended
Rise of the Ronin 16 GB minimum and recommended 1080p/30 FPS lowest minimum and 1080p/60 FPS standard recommended; both targets are upscaled
S.T.A.L.K.E.R. 2 16 GB minimum; 32 GB recommended Low/1080p/30 FPS minimum; high/1440p/60 FPS recommended
Hogwarts Legacy 16 GB minimum and recommended 720p/30 FPS low minimum; 1080p/60 FPS high recommended

Sources: [Square Enix’s 2025 Steam listing for FINAL FANTASY VII REBIRTH, Koei Tecmo’s Steam listing for Rise of the Ronin, GSC Game World’s 2024 Steam listing for S.T.A.L.K.E.R. 2, and Warner Bros. Games’ Steam listing for Hogwarts Legacy.] A game’s system-memory requirement is not its VRAM requirement. If choosing a RAM kit, also confirm that its capacity and type are compatible with your motherboard and processor.

How much storage does a gaming PC need?

There is no single storage total that fits every game library. The listed space for these four games alone ranges from 85 GB to 160 GB; a larger library, updates, and other files require additional usable capacity.

Game Listed available storage Drive requirement or preference
Hogwarts Legacy 85 GB SSD preferred; HDD supported
FINAL FANTASY VII REBIRTH 155 GB SSD required
Rise of the Ronin 155 GB SSD required; NVMe SSD recommended
S.T.A.L.K.E.R. 2 160 GB SSD required

Sources: the game listings linked above. Treat each figure as that game’s listed available space, not as a recommendation for the capacity of your entire drive. Add the installed sizes of the games you expect to keep, then allow room for updates and your operating system and other files. Check the current listing for each game: some require an SSD, while others only prefer one or support an HDD.

What graphics card do you need for your games?

Start with the game’s listed GPU requirements and the target you want to achieve. The examples below show why graphics needs cannot be reduced to a single card or VRAM number: targets vary in resolution, frame rate, quality settings, and upscaling. A minimum specification is not equivalent to a recommended specification, and neither is a cross-system performance guarantee.

Sources: the game listings linked above. These are publisher-listed examples, not results from a shared benchmark, so they should not be read as a direct ranking of the cards across brands. Compare GPU performance as well as VRAM capacity; VRAM alone does not establish how fast a card will run a game.

Use VRAM examples as context, not a universal rule

AMD’s Radeon guidance gives examples of 8 GB cards for 1080p, 12 GB examples for 1440p, and 16–24 GB examples for 1440p/4K and 4K. Those are AMD product examples, not a prescription for every GPU or game. AMD dates its underlying peak-usage test to June 28, 2023, and its Far Cry 6 comparison test to May 16, 2023.

How system RAM differs from GPU VRAM

System RAM is the computer’s main memory; VRAM is memory used by a graphics card. AMD explains that discrete graphics cards have dedicated video memory, while integrated graphics use Unified Memory Architecture and share system memory. A system with integrated graphics therefore does not turn its total RAM into dedicated VRAM.

AMD recommends leaving the UMA frame-buffer setting on Auto for most workloads. Avoid treating a larger manually reserved UMA buffer as a substitute for a discrete GPU’s dedicated VRAM; check your system’s firmware guidance if you need to change memory settings. See AMD’s explanation of UMA frame-buffer sizing.

A practical way to choose parts

  1. List your target games. Open each game’s current publisher or store requirements and note its minimum and recommended specifications.
  2. Set the experience you want. Specify resolution, expected frame rate, and graphics quality. Requirements for 1080p/30 FPS do not establish what you need for 1440p/60 FPS.
  3. Match the GPU to that target. Compare the listed GPU examples for the relevant target, then consider GPU performance and VRAM separately. Do not assume similarly sized VRAM means similar performance.
  4. Size system RAM from the game requirements and platform. The examples here commonly list 16 GB, while S.T.A.L.K.E.R. 2 lists 32 GB recommended for its stated high/1440p/60 FPS target. Confirm motherboard and processor compatibility before buying a kit.
  5. Estimate storage from your library. Add the listed space for games you expect to install and leave additional usable capacity for updates and other files. Confirm whether each game requires an SSD, prefers one, or supports an HDD.
  6. Check the whole build before purchase. Verify GPU fit in the case and compatibility with the power supply, motherboard, and other components. A game requirement alone does not establish that a particular card will fit or work in a particular PC.

Requirements and hardware change. Recheck current game listings and component compatibility when choosing parts; the examples cited here were accessed October 7, 2026.
