Ryzen 9 5900X + AMD Radeon RX 6900 XT Build Under $3000

There truly has never been a better time to build a brand-new PC for gaming enthusiasts and professionals alike. AMD has not only announced a brand-new series of Zen 3 Ryzen 5000 Series CPUs – that absolutely crush their competition, both in single-core dependent gaming performance. as well as for multicore reliant workstation loads – but they have now also announced a new series of Radeon RX 6000 Series GPUs that synergize perfectly with their processors. This synergy manifests in an innovative feature called Smart Access Memory, which allows for both CPU and GPU to share a memory, resulting in a sizeable boost in performance; which was proven by AMD via the use of gaming benchmarks.

Of course, it is not only gaming builds that benefit from this synergy, as these new Ryzen 5000 Series CPU combine their last generation’s multicore performance, together with the all new CCX architecture that allows for peak single core performance as well. This means that no matter the type of application, be it single core dependent loads (like gaming or CAD), and multi-core dependent applications (like video editing or compiling), AMD provides the best possible performance available.

Now that DDR4 RAM has also reached its peak, and next-generation gaming consoles have just released – which use AMD CPUs and GPUs, meaning that game developers will most likely build games based on AMD’s Zen 3 and RDNA2 architecture – are factors that create a timely sweet spot for PC building.

For this occasion, we have created the most optimal workstation/gaming hybrid build, that makes use of AMD’s CPU flagship, the Ryzen 9 5900X, in unison with their GPU flagship, the Radeon RX 6900 XT. This setup will be minimalistic, aesthetically, but still pleasant in its simplicity; focusing rather on optimal performance for its price. The overall cost for this rig is $2,999.88.

Data Transfer Bandwidth25,600 MB/s (PC4 25600)
Dimensions45(H) x 134(L) x 8(W)mm
Heat SpreaderAluminum heat spreader

The DDR4 memory type is just about ready to wrap up its lifespan, which is great news for PC builders, as it not provides its full performance potential at a fraction of the cost of its original price. The most optimal speed for DDR4 RAM has proven to be 3,200 MHz with a CAS latency of 14 cycles. Due to this, we recommend 32 GBs of TeamGroup’s, 3,200 MHz C14 T-Force Dark Pro memory.

This RAM kit is devoid of RGB fluff, and instead allocates its expense to pure performance. It has incredible CL timings of 14-14-14-31, all original, high-quality, IC chips, and a Samsung B-die, which is optimized for AMD’s Ryzen processors. The T-Force Dark Pro also has an excellent cooling solution: using a five piece heatsink that has a unique trench design and an all-aluminum heat spreader.

It is this cooling solution which allows for stable, and frequent, overclocking, without the fear of overheating or damaging the memory kits. Also included, is XMP 2.0 compatibility, for one click overclocking. Finally, to enhance performance, this RAM makes use of JEDEC RC 2.0 technology: A custom circuit board that separates power and signal layers, keeping them as far apart as possible in order to minimize interference.

The TeamGroup T-Force Dark Pro currently sells for $129.99 for two sticks of 8 GB RAM; and we recommend purchasing two of these sets, for an overall storage of 32 GBs of dual channel RAM. This will cost $259.98, and this price includes a lifetime warranty.

Motherboard CompatabilityATX
Item Dimensions LxWxH22.36 x 12.91 x 26.5 inches
Case TypeMid Tower
Total USB Ports3

The case to be used for this build needs to be something simple, yet elegant. Something that catches the eye, without the need for an overflow of flashy lighting displays within. The Fractal Design Vector Rs Blackout is perfect for the task.

The Vector Rs Blackout has a clean interior and a minimalist exterior that makes use of an ARGB accent running across the front and the top of the case. It also has three tinted, bolt-free tempered glass, panels on the left, right, and top of the case, with sharp angles that refine its exterior design, but also give it optimal airflow pathways. It has counter-angled air intakes, which allow for unrestricted airflow and also trap unwanted noise. Given the fact, that the components of this build have been specifically chosen to operate as near-silent as possible, adding them to this case will mean that the setup will operate inaudibly. The top glass panel can also be converted to a filtered ventilation that includes a cooling bracket and vent cover, if need be.

The Vector Rs Blackout includes three pre-installed 140 mm case-fans (namely, the Fractal Design Dynamic x2 GP-14), and the case can accommodate up to nine case fans, if additional cooling is needed later down the line. In regards to storage connectivity, the Vector Rs Blackout allows for a total of six 3.5” HDD/SDDs, as well as two additional 2.5” SDD storage units. The top I/O ports are comprised of two USB 3.0, one USB 3.2 Type-C slots, and two audio jacks. Finally, a R1 controller is also included, which can be used to set colors and effects for its RGB display.

Though somewhat expensive for a PC case, the $195.72 price tag of Fractal Design’s Vector Rs Blackout is a necessary expenditure; not only to provide the means for optimal cooling, but also to tie together the aesthetics of the interior components in the best manner possible.

Storage – Sabrent Rocket 4

Sabrent Rocket 4
Digital Storage Capacity2 TB
Compatible DevicesThis drive is compatible with servers and arrays that accept M.2 2280 PCle drives
Item Dimensions LxWxH3.15 x 0.86 x 0.11 inches
ColorNVMe Gen4 TLC SSD

Taking full advantage of the PCIe 4.0 compatibility of the Ryzen 9 5900X, as well as the plethora of PCIe 4.0 M.2 slots of the MSI Meg X570 Unify, we have included a 2 TB Sabrent Rocket 4 M.2 NVMe SSD.

This storage unit features amazingly fast speeds: reaching up to 5,000 MB/s and 4,400 MB/s of peak sequential read and write speeds respectively, as well as random 4K read and write speeds of 750,000 IOPS each. It does so by making use of a Toshiba BiCS4 96L NAND, operated by a Phison PS5016-E16 controller. Because the Sabrent Rocket 4 comes in a 2 TB version, we can still have two open M.2 slots on the motherboard that can be used if storage demand increases. Also, it is important to note that this SSD has an amazing level of endurance. The 2 TB variant has a Terabytes Written (TBW) value of 3,600 TB, as well as an MTBF of 1.7 million hours – all backed by Sabrent’s 5-year warranty.

Given that the Sabrent Rocket 4 also has Advanced Wear Leveling, Bad Block Management, Error Correction Code, Over-Provision, as well as Sabrent’s free Acronis True Image software, two terabytes of this M.2 NVMe SSD are well worth its $399.97 price tag.
