PCIe X16 slot compared to AGP 8x:

Power handling of each slot type:

AGP (non-Pro) - features 25W typical or up to 42W max on some systems.
AGP Pro (50) - features 50W in the Pro 50 format. The Pro 110 version initially offered 110W but never really caught on.
PCI Express X16 - features 75W of power available at the slot and will be widely available. It's a 164-pin slot with 64-pins for data and 100-pins for power.
For more than 75W an extra 6-pin power connector adds an additional 75W of power per 6-pin connector.

Articles dealing with the additional 6-pin power connector for 150W duty (75W slot + 75W adapter). An ATX12V v2.0 power supply features 24-pin main power, 4-pin 12V CPU power, and additional 6-pin 12V Video power connectors.

All I can say is: Check out the benchmarks online. Look for both speed and quality and then check out the price of each model. The ATI Radeon X800 and NVIDIA GeForce 6800 class cards all pack a powerful rendering punch. Enthusiasts, gamers and power users should look for those card exclusively.

ATI Radeon X series

All R420 derived parts (AGP 8x): Radeon Xx00 xxx
names such as: Radeon X800, X600 or X200 in XT, Pro or SE flavors
All R423 derived parts (PCIe X16): Radeon Xx00 xxx
names such as: Radeon X800, X600 or X200 in XT, Pro or SE flavors
Note: Only ATI's X800 class videocards use the new R420/R423 cores.The X600 is a revised 9600. And, the X300 is a revised 9200.

NVIDIA GeForce 6 series

All NVIDIA NV40 derived parts (AGP 8x): GeForce 6xxx
names such as: GeForce FX 6800, FX 6600, FX 6200 in Ultra, plain or other flavors
All NVIDIA NV45 derived parts (PCIe X16): GeForce PCX 6xxx
names such as: GeForce PCX 6800, PCX 6600, PCX 6200 in Ultra, plain or other flavors

The NVIDIA family include the following parts (of previous cores rebranded for PCI Express duty):

The other chips from NVIDIA, based on the older cores (but in PCI Express format) will contain a bridge chip:
NVIDIA GeForce PCX 5900
Based on the DX9 GeForce architecture, this new GPU delivers extreme graphics power and performance for extreme gamers.
*assumed to be the GeForce FX 5900 in PCIe X16 format
NVIDIA GeForce PCX 5750
Designed for high-performance gaming with NVIDIAs full suite of cinematic effects and an unmatched feature set.
*assumed to be the GeForce FX 5700 in PCIeX16 format
NVIDIA GeForce PCX 5300
Delivers state-of-the-art, best-in-class features and the reliability users have come to expect from NVIDIA, at an affordable price.
*assumed to be an enhanced GeForce FX 5200 in PCIe format.

Quick Chart Reminder:

Keep in mind these are all reference speeds for the products above. Some videocard manufacturers clock their cards slightly higher. But, these are the recommended settings from ATI, Matrox, NVIDIA and others. The majority of videocards run exactly as specified by the manufacturers.

A few important videocard performance calculations:

Bandwidth (GB/s): Memory clockspeed * Data Multiplier (DDR = 2) * Bus Width (in Bytes) = Maximum Memory Bandwidth
Actual bandwidth calculating requires caution. There are decimal and binary equivalents involved together. Fortunately, marketing departments throw all that technically correct jargon out the door. Or would that be "Windows"? Ha. Anyway, below are the decimal-only values with no correctional factors included.
Pixel Fill Rate: GPU Core clockspeed * pp (pixel pipelines) = Maximum Pixel Fill Rate
A purely decimal calculation. It's simple when the manufacturer tells you the numbers (accurately).
Texel Fill Rate: Pixel Fill Rate (see above) * tmu (texture mapping units) = Maximum Texel Fill Rate
A purely decimal calculation. It's simple when the manufacturer tells you the numbers (accurately).
That's all for the calculations for now. More later perhaps.
