Wireless cards

[Dabomb18359]

I have a 32-bit $13 wireless card from Fry's Electronics.
To start with, it works and is simple enough and I don't notice a lack of speed or problem really.

1. Sometimes it overheats, but what does this actually do? I have never had anything bad happen due to overheating, but it's obviously nothing good.

2. When you buy a more expensive wireless card, does it 1) not overheat as much and/or 2) get more better further away signals?

I know wireless cards have the whole "8x range thing in the Sunday newspaper ads, but I thought they just take the signal from where you are. Can they actually extend out and "grab" further away signals if you buy a more expensive one?
Thanks for the help!

Wireless G B or A? Each has their own standard ranges, though a crap card will underperform/frequently drop signals.

I don't know what overheating does to wireless cards, but I'd assume it shortens it's lifespan, until eventually it just won't work at all?
