ABOUT THIS BUILD

Consider this Ryzen 9 9950X3D2 Dual Edition and RTX 5090 list only with a workload that justifies 96 GB of system memory and 32 GB of graphics memory. The 7000D case and 420 mm AIO make the physical installation a substantial part of the plan. Check radiator placement, memory support and the delivered total before accepting this target. Budget is a planning target, not a retailer quote. Image is an illustration.

The build review

Based on selected hardware and published requirements

Updates with your selection
Our take

You have room to explore. Let the workload choose the next upgrade.

CPU cores16 cores
System memory96 GB
Dedicated video memory32 GB

CS2 · Windows memory requirements

Both recorded memory capacities meet the CS2 Windows minimum. Other requirements remain unchecked.

What you have

GeForce RTX 5090 32G VENTUS 3X OC is your selected graphics card. Its 32 GB memory is capacity, not a speed score.

What decides the result

These two checks use Valve’s Windows minimum requirements. They do not establish frame rate, preferred settings or support for another game.

Capacity references only · meeting these is not a performance score or full application approval.

Still to verify for CS2

  • Check the operating system and CPU against Valve’s Windows requirements; a core count alone cannot verify the processor.
  • Verify DirectX 11 and Shader Model 5.0 support for the exact GPU and installed driver. Shared system memory does not verify the video-memory requirement.
  • Confirm at least 85 GB of free storage on the installation drive. The capacity printed on an SSD is not its available space.

This changes the comparison advice below. Valve’s minimum memory requirements stay the same.

The next move

For 1440p, compare CS2 tests at 2560 × 1440 with the same game version and preset. Check average frame rate and 1% lows against your monitor’s refresh rate.

THE CHOICES BEHIND THIS PARTS LIST

Who this build is for

A large, high-capacity enthusiast configuration combining Ryzen 9 9950X3D2 Dual Edition, a 32 GB RTX 5090 and 96 GB system memory. It requires careful workload justification and installation planning.

Why these components are together

The CPU and GPU are separate high-end choices, not a guarantee of proportionate benefit in ordinary applications. Confirm that your workload uses the extra compute and memory resources.

The 96 GB memory kit and 4 TB 9100 PRO expand capacity and storage capability. Verify the exact kit, firmware, M.2 connection and heatsink requirements rather than relying on capacity labels.

The 420 mm Liquid Freezer III Pro, 7000D AIRFLOW and 1200 W Straight Power 12 make physical installation and cabling major parts of the plan. Read the exact radiator and motherboard pump-clearance guidance.

Tradeoffs and checks before ordering

  • Board support and the installed BIOS must cover the exact Dual Edition CPU.
  • The radiator and fans must fit as a complete stack in a documented position.
  • Check the GPU's approved power connection, bend space and support arrangement before closing the case.

What to change first

Validate the current workload before adding still more hardware. External backup, application workflow and display requirements can be more relevant than another specification increase. Record real project results instead of treating the flagship label as evidence.

Document checks for this starter (English)

Manufacturer documents, checked against the original parts list. These are not assembly or benchmark results.

Confirm firmware before ordering
Unresolved

Ryzen 9 9950X3D2 Dual Edition (100-000001978) + MSI MAG X870 TOMAHAWK WIFI

The exact CPU's minimum BIOS is still unconfirmed. This board's Flash BIOS Button can update firmware without a CPU or memory, but that capability does not identify the required version.

Build decision: Match 9950X3D2 Dual Edition (100-000001978) in the X870 TOMAHAWK WIFI CPU Support table and read Result. Ask the seller which BIOS is installed on the board being shipped. If an update is needed, follow this board's manual, page 72; X870E and MAX are different models.

Still to check: No minimum version or out-of-box boot claim is made here. The exact CPU support row and the delivered board's installed BIOS still need confirmation.

Document review:
The selected 96 GB kit is XMP, not an EXPO promise
Unresolved

Kingston KF560C32RSK2-96 + MSI MAG X870 TOMAHAWK WIFI

Kingston specifies two 48 GB modules, a DDR5-4800 default and Intel XMP 3.0 profiles. MSI lists AMD EXPO support for this board.

Build decision: Do not describe this combination as EXPO-validated. Confirm support for this exact 48 GB-module kit before purchase.

Still to check: Exact QVL coverage and profile operation on the selected CPU/BIOS remain unresolved; capacity alone does not settle them.

Document review:
Keep the USB4-sharing socket free unless needed
Document finding

MSI MAG X870 TOMAHAWK WIFI

M2_2 shares bandwidth with rear USB4. M2_3 shares with PCI_E3. M2_1 is the uncomplicated first-drive choice.

Build decision: Start in M2_1. Before expansion, read both sharing notes; forcing M2_2 to x4 in BIOS disables the rear USB4 ports.

Still to check: SSD heatsink fit and firmware settings remain to check on the delivered board.

Document review:
A 420 mm mounting position does not prove stack clearance
Unresolved

Liquid Freezer III Pro 420 ACFRE00181A + 7000D AIRFLOW

ARCTIC lists a 458 x 138 x 38 mm radiator. CORSAIR documents 420 mm radiator positions at the roof and front.

Build decision: Select a position before buying; compare the complete radiator/fan stack and hose route, not just the 420 mm label.

Still to check: Full stack clearance and pump/M.2 interference on the exact X870 board remain unresolved. Use ARCTIC's motherboard checker before ordering.
