Best PCI Express (PCIe) Card For $65-$85: None
Choosing to forgo this entire price segment is bound to be a controversial decision, so some explanation is in order.
This price segment holds three excellent performers: the GeForce 9600 GSO, the Radeon HD 4670, the Radeon HD 3850, and the GeForce 9600 GT. The GeForce 9600 GT is a particularly great card now found at an $85 price point. So, why can't we recommend them?
Here is our reasoning: the Radeon HD 3850, the GeForce 9600 GSO, and the Radeon HD 4670 can be found for about $80. At this price they're an excellent deal, but for $5 more you could purchase a GeForce 9600 GT that would offer a great deal of improvement and would thus make it difficult to recommend the $80 cards.
However, recommending a GeForce 9600 GT is impossible when the Radeon HD 4830 can be found for less than $5 more.
The bottom dropping out of Radeon HD 4830 prices is unexpected and represents a huge boon for the gamer without a lot of cash. So we've chosen to recommend that buyers either save as much money as possible and go with the Radeon HD 4650 or pay the extra $30 for a serious performance boost and get the Radeon HD 4830.

Best PCIe Card: $200 To $350
Best PCIe Card For $200 - $250: None
The new GeForce GTX 260 is a great card, but its price has remained in the $240 range while the Radeon HD 4870 can now be found for under $200. At a $45 spread we can no longer recommend it over the Radeon HD 4870, but Nvidia will likely drop the price to remain competitive in due time.

HONORABLE MENTION: Best PCIe Card For ~$310: Tie
I'm putting in the following recommendations in case the $265 Radeon HD 4850 X2 deal doesn't last. For ~$310, a pair of GeForce 9800 GTX+ cards or a single Radeon HD 4850 X2 2 GB card will deliver about the same performance. With the price spread, you can see why I'm recommending the Radeon HD 4850 X2 1 GB so highly.

Best PCIe Card: $350+
With exponentially increasing prices over $300 offering smaller and smaller performance boosts, we have a hard time recommending anything more expensive than a Radeon HD 4850 X2. While the Radeon HD 4870 X2 and the GeForce GTX 295 perform impressively in multiple-card configurations, there’s just not enough of a gain compared to a Radeon HD 4850 X2, unless you play at resolutions beyond 1920x1200.
Then again, while we often recommend against purchasing any graphics card that retails for more than $300 from a value point of view, there are those of you for whom money might not be much of an object, who can afford a 30” LCD monitor, and who require the best possible performance money can buy. For those of you, we recommend the following cards:
