Agree, there is no difference between a cheap one or an expensive one. I have 3Com and Network everywhere. The former cost about $40 and the latter cost about $20. They are the same especially you plan to get a cable modem where 10/100 mbps have plenty of room for your connection.
My question is nearly the same I currently have a DSL connection and just completed building a new pc the old system has a Kingston etherx 111tx this card seems to work very well but after looking there are some like model 120tx not sure what the difference is..... Are they faster?? I get over 1meg download but card wouldnt improve on that would it?? card is cheap to less than $20.
I'd stick with the Kingston that works with your DSL.
AND...I don't beleive all ether cards are the same.
I also have a kingston for my ADSL. And when I tried to use my RealTek, (both cards are 10/100 base T), The realtek would NOT connect to the internet. I've installed the local IPX and internet TCP/IP setting many times....I made NO mistakes in the networking control panel. The dang Realtek simply would'nt connect through my DSL modem...for whatever reason.
Thanx for the input Bud, Just to let you know I got a network card from work an Intel pro installed it in the old machine and it works just fine!! I was kind of surprised but for primary machine I will use the kingston.
