AGP is just way to connect the graphics card to your motherboard. The 2X,
4X, 8X are connection speed, 4X is twice the speed of 2X, 8X is twice the
speed of 4X and so on. You can for example put AGP 8X card into AGP 4X
motherboard but the speed will only be 4X.

None, AGP is a bus which connects the graphics card into the motherboard of
your computer. The graphics card is connected to the display device using
different kinds of connectors like DB15, BNC, DVI and others. Usually
graphics cards (for PC) have either DB15 or DVI output connector(s) and DVI
can be usually converted to DB15 because DVI-I connectors should have DVI-A
(A= Analogic) pins connected and used. There are different kinds of
connectors at both ends: graphics card and monitor and you can try to
determine what you got and maybe ask here what recommendations you are
given. For example if you have DVI on both monitor and graphics card it
should be the best choise.

I am not going to check from the web what the specs of 200ES are but it very
likely has DB15 and/or BNC input. As long as you have the right cable you
can hook it up to the TNT2 and it should work (I cannot guarantee that the
card or monitor are not broken). <- Sick world that have to put that kind of
disclaimers, but the world changes.. if I don't it is a bomb-sure invitation
for someone to find 'error' and bash for it. *sigh*

Small correction: The AGP 'speed' does not make any significant difference
performance-wise. Advanced Graphics Port is just a different (newer) standard to
Peripheral Component Interconnect. By definition all AGP cards should be faster than PCI
cards. Newer cards (mostly with 8X emblazoned on them) may not work in older computers due
to them using a different voltage.

Same way as having car with top speed of 300 kph and 150 kph, if you don't
drive faster than 150 kph, indeed there is no difference. AGP 8x _does_ have
twice the _bandwidth_ over AGP 4x, it is a different matter if this is used
by applications. But that is nitpicking so chill out ffs, always, always
have to mention every minute little tiny dickwick detail otherwise someone
corrects you.

Alright. Background information: I work for a 3D graphics hardware vendor
and I have been programming for 15+ years and have a fairly good idea what
AGP 8x can and cannot do. Thank you. <- Does that make any difference to
anything? No. Why then it is important to mention? I don't know, you tell
me.<!-- ~MESSAGE_AFTER~ -->

Okay. I'll go into detail. AGP 'speed' only means anything when transferring textures from
main memory. Most cards have enough memory on board for that not to be an issue. AGPX8 is
slow. AGPX4 is slower etc.... You wouldn't want to use this feature of AGP which was only
included to sell video cards to the uninformed.

Before we waste any time, you are a programmer, or end user?

I am curious, how does that change the fact that AGP 8x has twice the
bandwidth over the AGP 4x? That is completely separate issue from the
question if the bandwidth is needed or not.

When GAME application is written, it must work on as wide range of hardware
as possible. This means the application is specificly engineered to work
from lower end to the higher end of the hardware spectrum, this fact must
have given you the impression that higher bandwidth is NEVER advantageous or
even usefull. You are plain wrong with this conclusion.

What feature are you referring to, the higher bandwidth, or DIME? I am
curious again, what practical experience you have on the topic? It would be
interesting to know if I am merely wasting my time or having a good
discussion.<!-- ~MESSAGE_AFTER~ -->

I am an end user with a little programming experience.

I would like to have a good discussion about this because end users seem to be hung up on
the AGP 'speed' when this generally has very little bearing on the performance of their
graphics card. DIME is hardly ever used by games programmers otherwise cards wouldn't have
so much memory on them. AGPX8 bandwidth is only about 2GB/s whereas the latest cards have
about 30GB/s. Sure, high AGP bandwidth is 'good' but not if graphics card bandwidth is
increasing as well. I really don't understand the point of AGP DMA or DIME unless its to
keep costs down.
And texture loading bandwidth doesn't really matter because most games load up the
graphics card memory with textures before the game or 'level' starts.

I don't think it's nitpicking. It's an useful bit of information to
know that from a gamer's point of view (asusming most of posters here
are gamers) there is no performance difference between x4 and x8 AGP
card. What is more important perhaps is a compatibility with the
motherboard. So chill out, heh heh. Nobody is saying you were wrong
here.
And I read the other lenghty post - very interesting, thanks for
taking time to write it.
