Trying to decide between some video cards for my MIL's computer. We just bought her a Canon HF100 and noticed her computer was in need of an upgrade at the same time to be of much use.

She has a dell vostro and it has a core2duo 6320

I am looking to spend less than $60 and am stuck between the following:

Nvidia 9600 GSO ~$60 (96 stream processing units)
ATI 3850 ~$60 (320 stream processing units)
ATI 4650 ~$55 (320 stream processing units)

I am gonna take a wild guess here and say that stream processing units can't be compared between designs?

Not gaming...video editing/encoding only.

Any help is appreciated. Thanks!

tomshardware has chart that compares a bunch of video cards against each other... i don't have the url handy, but it'll give you a rough idea of how they stack up against each other.

I've been over to Tom's but it seems everything over there is focused on gaming. I am looking for video editing/encoding.
