Conclusion:

Sapphire has done a great job with AMD's 4670 and includes an amazing bundle and value for the sub-$100 card. It easily surpasses the 9500GT and if you're looking for a card under $100 it is the fastest. However, the GeForce 9600 GT and Radeon 3870 can both be had for about $100 online and offer a lot more bang for the buck than the 4670. If you don't need it then obviously it isn't worth getting or if you're on a very tight budget but if you can we recommend going for either of those cards before the 4670 and putting down the $100. Of course over time the 4670 will probably see price drops as well so we'll have to re-evlaute but for now the 4670 is a sure winner but the Radoen 3870 or 9600 GT are definitely worth looking at.

Pricing:

The 4670 is available for $79 in the market place now. That sets it at around the cheapest  512MB DDR3 9500 GT on the market which is quite an excellent value. As said though a GeForce 9600 GT can be had for around $100 so if you can step up a bit it will provide better performance. There is somewhat of a gap in between $80 of the 4670 and $160 of where the 4850 has settled.
