Estas 2 coisas fazem alguma diferença na performance, máximo de overclock ou image quality?
nunca notei nada de especial...
A placa é uma 6800GT AGP


Cumprimentos

desligados normalmente dão mais overclock na placa , e o hit de performance quase não se nota

ja agora aproveito para expor a seguinte duvida,os fastwrites e o sideband adressing so existem em agp ou em pci express tb?

só em agp !

para que servem já agr?

same question here! :o

AGP vs PCI

As computers became increasingly graphically-oriented, the graphics card became far more important than other PCI devices, and, thus, the AGP slot was developed.
AGP slots are superior to PCI for graphics cards because they provide a dedicated pathway between the slot and the processor, allowing for faster communication between the two.
In addition, AGP uses sideband addressing, meaning that addressing for packets is carried outside of the packet, meaning that the entire packet does not need to be read to get addressing information.
In addition, to load a texture, a PCI graphics card must load it from the hard drive into the system's RAM, then load it from the RAM into the card's framebuffer.
An AGP card is capable of reading textures directly from system RAM using GART (Graphics Address Remapping Table).
GART reapportions memory for texture storage, "tricking" the CPU into "thinking" that the textures are in the card's framebuffer, allowing the graphics card to access them directly.
Thus an AGP slot is far superior to a PCI slot for graphics card purposes.

ou uma explicação mais clara:

Sideband addressing - Like a letter, all requests and information sent from one part of your computer to the next must have an address containing "To" and "From." The problem with PCI is that this "To" and "From" information is sent with the working data all together in one packet. This is the equivalent of including an address card inside the envelope when you send a letter to a friend: Now the post office has to open the envelope to see the address in order to know where to send it. This takes up the post office's time. In addition, the address card itself takes up room in the envelope, reducing the total amount of stuff you can send to your friend.
With sideband addressing, the AGP issues eight additional lines on the data packet just for addressing. This puts the address on the outside of the envelope, so to speak, freeing up the total bandwidth of the data path used to transfer information back and forth. In addition, it unclogs system resources that were previously used to open the packet to read the addresses.
