Jeremy Q.Top after-sales support!
I received my PC with a faulty graphics card. The aftersales service from FlowUP was ultra efficient. They replaced my card on the very same day (shout-out to Mickael, who was truly great).
Lenny N.No regrets!
I invested in the BlackHawk and it’s pure joy. With the Cooler Master MK770 keyboard and the MSI IMMERSE GH20 headset it’s softer than my bed. And yet I love my bed—trust me!
The after-sales service is really high quality. The responses and support are fast, with kindness and genuine human interaction.

FAST DELIVERY AND EXCELLENT PERFORMANCE.
I received my PC in exactly 9 days! (Order placed on 10 February and received on 19 February). I would like to thank the Flow Up team for their speed and sincerity.
As for my PC, it’s the Savannah v2 with an RTX 5060 Ti and a Ryzen 7 5700x with 16GB RAM. It’s perfect for playing in 1440p at high/ultra settings on big triple-A titles with 80/120 fps, and for esports at 240fps in low/high settings (depending on the games).

amd ryzen 5 5600
The AMD Ryzen 5 5600 is an appealing option for mid-range PCs, suited for gaming as well as photo and video editing, while still offering excellent value for money.
With 6 cores and 12 threads, it delivers solid performance and sits just below the Ryzen 5 5600X in terms of price. The Ryzen 5600 uses a chiplet design with 32MB of L3 cache, bringing it closer to the 5600X, while the 5500 model—based on the 5600G—disables the integrated GPU, reducing L3 cache to 16MB and supporting PCIe 3.0 instead of 4.0.

AMD Ryzen 9 9900X3D
The AMD Ryzen 9 9900X3D is a processor in the high-end segment aimed at intense gaming and advanced productivity, thanks to the combination of the Zen 5 architecture and 3D V-Cache, which frequently improves gaming performance when the workload is limited by the CPU. It is based on the AM5 platform and supports DDR5 as well as PCIe 5.0, with a configuration of 12 cores / 24 threads tailored for streaming, editing and multitasking.
In a very brief comparison, the Ryzen 9 9950X3D stands out mainly due to a higher number of cores, giving it a clearer advantage for heavily multi-threaded workloads (rendering, encoding, calculations), while the 9900X3D keeps a more balanced approach oriented towards gaming performance and versatility.
Memory:
- 4 DDR5 slots, up to 256GB
- Frequencies up to 8000+ MT/s (OC)
- Dual Channel with support for AMD EXPO™ and ASUS AEMP
Storage:
- 4 × M.2 NVMe (2 × PCIe 5.0 x4, 2 × PCIe 4.0 x4)
- Integrated M.2 heatsinks
