Same thing over and over again...
Let's rephrase:
* If for emulation, glide64 will suffice; no need for a better card. Glide64 is very fast as you might know.
* GeForce4 MX is a bad card. It lacks good stuff that's on other cards. Don't buy this card; instead, go for a GeForce3 Ti. It's cheaper and better.
* And lastly, don't buy the newest cards! In a month or two, the price will have dropped!
* About the raedon: It's very good and very expensive! This will make the price of geforce4 drop, hence you might want to buy a gf4 instead of raedon later. Or buy a less good raedon.
That's all...
