Tech Report (which I think is the best hardware site on the web) published its review relatively late in the day. Not only did the HD4850 beat the 8800GTX and 9800GTX in practically every game, but in some cases, it's faster than Nvidia's new GTX 260. At $199, this thing is amazing.

AMD is holding back on the big brother of this card (the HD4870) because there isn't enough GDDR 5 memory available yet. That card is going to be a lot faster than this one. Pretty soon after that, AMD will probably put two of those chips on a single card. Like I said above, I don't see how Nvidia can do the same, given the size of their new chip. I think Nvidia is going to feel some real heat from AMD this year.

I've been thinking AMD was dead, but now I'm almost considering buying their stock.
