You don't need high end top of the line, but you do want all the memory that poser can use for the best previews.

Thing is, good cards have dropped so much in price, not having a decent card is almost a crime.

You can get a ati hd4850, which was the best card buy under $300 last year for $100 shipped right now.. and its fast enough to even run most games with everything on, and in hd res.

And if you buy something older, odds are it won't be supported by windows 7. (My ati x1950 pro which is 2 years old is not supported with new drivers in windows 7, believe it or not!)

I think in the ati series anything less then the HD series has no more driver support.

Way too many people take way too many things way too seriously.
