A lot of energy is spending the search of the non-existing "Holy NIC Grail".
Most of the activities done by Home user, i.e. Internet, gaming, etc. use small amount of the capacity of any 100/10 NIC. (Actually 10 Mb/sec NIC will suffice a lot of times).
The differences between cards kick in when the Network consists of many computers, doing heavy network exchange. In other words it does not matter which card you are using for small home Network.
Tom's hardware compared three NICs. (Aug. 2001)
I used Pricewatch.com to find the best price for these NICs.
1. 3Com 3CR990-TX-97 - $80
2. 3Com 3C905C-TX - $30
3. SMC 1211TX - $13

"Well, there is some difference between Network cards. The difference was not that great. Some cards did have better performance than others, but over all most of the cards performed within acceptable ranges. "
If you read the rest, you can infer that if there is a difference it will impact high volume cooperate Network, not three computers sharing the Internet at home.
However, if the main concern is reduction of anxiety. It seems that the Intel NICs are good for Network, as Prozac? is good for the mood. Most of the ?Plumbers? bet their livelihood on Intel cards.
