💰 $20 CAD • 🛡️ 30-day limited warranty
Cleaned, inspected, and tested in the workshop.
😊 In simple terms
An older graphics card for $20 to troubleshoot a compatible desktop or add display options. This is not a modern gaming card.
It has 1 GB of video memory, two DVI-I ports, one HDMI, and one DisplayPort. The four ports do not guarantee four simultaneous screens.
Before buying: your PC must have the necessary space, a PCIe x16 slot, and two 6-pin PCIe power connectors. A quality 500 W power supply is recommended for the complete PC, but its actual capacity and the rest of your configuration must be checked. This full-height card is not a low-profile model for small cases.
Tested under Windows 11 by our technician in the workshop PC. A suitable driver must be installed on your computer; older drivers and 1 GB of memory limit recent games. Card sold separately, with protective packaging and a 30-day limited warranty from the billing date.

🎯 Uses and Limitations
- Multi-screen office work: distribute documents, spreadsheets, and windows on a compatible configuration.
- Troubleshooting: replace a failed card or add a dedicated circuit to a compatible desktop. The name Dell OptiPlex, HP EliteDesk, or Lenovo ThinkCentre is not enough to confirm compatibility.
- Standard multimedia: videos with YouTube, VLC, or Netflix depending on codecs, drivers, software, connection, and PC; no universally smooth 1080p playback guaranteed.
- Classic games and emulation: to be assessed according to title, version, processor, and RAM. The year of a game alone does not guarantee its operation.
Not recommended for: recent AAA games or current competitive gaming as a main goal, hardware ray tracing, professional 4K editing, and modern industrial rendering. Its 1 GB of VRAM and older drivers are significant limitations.
🎮 Games: Realistic Expectations
No game-specific tests or documented FPS results are provided. The examples kept from the sheet do not constitute a guarantee of smoothness or compatibility of current versions.
- Classic examples cited: Stardew Valley, Terraria, Among Us, Grand Theft Auto IV, 2D games, retro emulators, and small browser games; exact version requirements to be checked.
- Minecraft: specify Java or Bedrock, version, mods, and textures before relying on its operation.
- Roblox: check the current service requirements; an older version does not guarantee current access.
- League of Legends and Dota 2: current versions and drivers to be checked. Lowering graphics does not solve a software incompatibility.
- CS:GO / Counter-Strike 2: distinct games; no promise for CS2.
- Rocket League: current version compatibility not verified.
- Not recommended as a purchase goal: recent Fortnite, Call of Duty: Warzone, GTA V Enhanced, Cyberpunk 2077, Hogwarts Legacy, and other recent AAA.
For a gaming PC, choose the card according to the game requirements and the entire configuration. The workshop can offer NVIDIA GTX / RTX or AMD Radeon RX options depending on availability and budget: 514-394-7794.
✅ Tests and preparation in the workshop
- Card opened and circuit dusted according to the sheet.
- Inspection and verification on the test bench by the technician.
- Operation under Windows 11 with drivers configured by the technician confirmed in the sheet.
These tests describe the store's checks, not an independent ATI/AMD or Diamond certification. Test duration, temperatures, noise, and performance measurements not provided.
The drivers are installed in the test PC, not automatically in your computer when you buy this card separately.

❓ Frequently Asked Questions
Does the 256-bit bus guarantee double performance?
No. Bus width is only one factor; architecture, frequency, memory capacity, drivers, and application influence the result.
Are four screens guaranteed?
No. The number and combination of screens must be validated; a native DisplayPort connection or a suitable active adapter may be required.
Is my 500 W power supply sufficient?
The displayed power alone is not enough. Check quality, actual capacity, two 6-pin PCIe connectors, and the power consumption of the rest of the PC.
Is it ready to work in all PCs?
No. It has been tested in the indicated workshop environment, but your PC still needs to be checked and a suitable driver installed.
