The 3COM 3C905cx-TXNM, also known as the 3C905-TX and 3C905TX-W, is a legacy 10/100 Ethernet PCI card produced by 3Com Corporation. This networking component was quite popular during the late 1990s and early 2000s when PCI cards were the primary way to add network connectivity to a desktop computer. Here are some pros and cons of buying these cards in today's market:

1. Compatibility with legacy systems: These cards can be used to add or upgrade network connectivity in older systems that do not support modern networking standards or lack built-in Ethernet controllers.

2. Reliability: The 3C905 series has a proven track record of reliability and stability, making it a popular choice for mission-critical applications.

3. Cost-effective: Compared to modern network interface cards (NICs) and network adapters, these cards are often available at a lower cost, especially on the secondary market.

4. Vendor support: 3Com Corporation still provides limited support for these cards, and the community of users and enthusiasts can often help with any issues that may arise.

1. Obsolete technology: These cards use outdated PCI technology, which is not supported by modern computers and operating systems.

2. Limited bandwidth: With a maximum throughput of 10/100 Mbps, these cards cannot match the speeds of modern network interfaces.

3. Power consumption: PCI cards generally consume more power than modern network adapters, which can impact system performance and energy efficiency.

4. Limited features: These cards do not offer advanced features such as Quality of Service (QoS), Power over Ethernet (PoE), or support for modern networking protocols.

In conclusion, the 3COM 3C905cx-TXNM PCI cards can be a viable solution for upgrading or maintaining older systems that require 10/100 Ethernet connectivity. However, their limitations in terms of technology, bandwidth, power consumption, and features should be carefully considered before making a purchase.

If you are looking to add network connectivity to an older system, the 3COM 3C905cx-TXNM PCI cards can be a cost-effective and reliable solution. However, it is essential to ensure that the system and operating system are compatible with the cards and that your networking requirements do not exceed the limitations of these outdated components. If you need faster network speeds, advanced features, or support for modern networking protocols, it may be worth considering a modern network interface card or adapter instead.
