Cheapest RTX 5080 in Czechia! The Gainward Phoenix model also features very good cooling

The RTX 5080 is among the most powerful graphics cards you can buy today for a gaming PC. The Gainward RTX 5080 Phoenix priced at 28 309 Kč after entering the discount code ALZADNY5 is a great option and is currently the cheapest card with this chip on the Czech market.

Quick summary:
✅ Makes sense if you are upgrading from an older generation (RTX 30 series or 20) and want the latest DLSS 4 with Multi Frame Generation. Verified reviews (4.8/5 from 41 ratings) praise temperatures around 70–72 °C under full load and quiet fan operation.
⚠️ Consider that the RTX 5080 requires a recommended 850 W power supply and has a TDP of 360 W, so check your power supply before purchasing. Some users report coil whine under high load. For RTX 4080 owners, the upgrade is not worth it — the jump in regular games is small.
💡 For 28 309 Kč you get a graphics card with 16 GB GDDR7 memory at 30 GHz, 960 GB/s bandwidth, a boost frequency of 2,617 MHz, PCI Express 5.0 interface, DisplayPort 2.1a and HDMI 2.1b support, Vapor Chamber cooling, Dual BIOS, and addressable RGB lighting.

Who is the RTX 5080 for

The main draw of the new Blackwell generation is DLSS 4 with Multi Frame Generation, which can generate up to three interpolated frames between every two “real” frames rendered by the GPU. In practice, this means that a game running natively at 30 fps can look like 120 fps.

The card has 16 GB of GDDR7 memory — compared to 12 GB in the RTX 5070, this is a key difference for 4K gaming and modern titles with ray tracing. Performance in common games like Cyberpunk 2077, Alan Wake 2, or Black Myth: Wukong is undoubtedly sufficient even for path tracing. For players coming from an RTX 3080 or older, this is a significant upgrade. For RTX 4080 owners, the difference is only around 15% in rasterization and primarily relies on the new DLSS 4.

What the Gainward Phoenix does differently

The Gainward brand has a reputation in Czechia for reasonable models rather than premium gaming brands like ASUS ROG or MSI Gaming. However, the Phoenix version of the RTX 5080 does not disappoint — reviews on Alza confirm that the Vapor Chamber cooling with Cyclone Fan fans keeps temperatures below 72 °C even under full load.

Practical note — the card is massive (332 mm length, triple-slot) and several users mention that a support bracket against PCB sag should be used in the case. The Dual BIOS feature allows switching between Performance and Silent modes with a physical switch. ZERO RPM Fan, in turn, means that the fans are completely off during normal office work or web browsing. The card supports undervolting — users report that after ten minutes of adjustments in MSI Afterburner, they reduced power consumption from 360 W to 250 W without a noticeable drop in performance.
