very few graphics cards will bottlenech with 4x agp. so no u shoodnt worry.

yes, AGP 8X (as multipler shows) should have to be twice as fast as AGP 4X. its actually not, its just ~10-40% performance increase. where it was expected to be 100%.

for your convinience, i'll describe all AGP standards on 32-BIT architecture.

PCI was 33Mhz @ 32-BIT register and has the data tansfer rate of 133MB/s

AGP was clocked @ 66Mhz with trasnfer rate of twice as of PCI, so 266MB/s

AGP2X =clock rate = 133Mhz, DTR= 532MB/s (Roughly) as it has capability to read on both rising and falling edges of signals.

AGP 4X = 266X4 = 1064MB/s (or ~ 1GB/s), clock rated at 266Mhz

AGP 8X = 266X8 ~ 2GB/s , clock rated at 533Mhz

and so does PCI-E = 16X ~ 1Ghz Clock rate and DTR ~ 4.15Gb/s

~ means not equal, but equalivent.

theoritically AGP8X was suppose to be twice as fast as AGP4X, but it isnt.
 
thanks for showing me that. appreciate it. not that i dont trust the other guy who posted to me response which i appreciate, but i know you have helped me alot in here when i come in arrow. if i put a agp8x card in a agp4x slot it wont make the video card incompatible with games or be any more unstable or affect anything right?
 
becaues im having so much trouble with this game im trying to play. and my brother's comp has a agp8x card and i was going to put it in mine and try to see if the game will load
