Don't go by the brand, go by the chipset. Intel is going to be Intel, obviously. D-link is probably going to be Realtek, which has never been famous for performance or reliability -- just price. One thing you'll notice about Realtek cards is that they waste a lot of CPU to do the same work a better card does with less.

As an aside, I don't reccomend D-link products.

Routers: We used to sell D-link wireless routers here at work, until one quarter we had 50% of them come back faulty. Not the same fault, or even the same model, but a variety of strange and interesting faults ranging between "refuses to let me go to hotmail.com" and "nearly caught fire".

Switches: A d-link router turned out to be the culprit of severe performance issues on our gigabit network. It negotiates as 1000baseT, but cheats by spamming pause packets until it's back down at 100baseT performance.
