My trusty FX5200 128mb AGP 8X has given excellent service over the past 4
years. I hope it will continue to do so but...

I'm hoping to upgrade my monitor from a 17" CRT to an LG L194WT 19"
Widescreen Monitor with a 1440x900 native resolution.

I can't find any sold evidence online that my graphics card will support
this resolution and, if it does, what will the available refresh rates and
colour depths be? Would I be likely to find that my system slows down at all
or would that not be related to the graphics card?

Nope. You should have done some searching with groups.google.com before
posting, you could have found the solution by yourself.

First, widescreen resolutions are not listed in the driver if there is
no widescreen display connected to the gfx card. That means you won't
see 1440x900 until you connect the display to your computer.

Second, some crap FX5200 and FX5500 cards have a buggy BIOS that limit
DVI output to 1280x1024 and below. So you might be forced to analog
connection if your card falls within this category.

Third, the available resolutions and refresh rates are limited by the
RAMDAC (for analog displays like CRTs or TFTs with VGA only) and the
TMDS transmitter (for digital displays, usually 60Hz and 72Hz). The
FX5200 has an SingleLink TMDS transmitter which means max. resolution is
1920x1200 at 60Hz if the card doesn't suffer from the above mentioned
bug. The colour depth is usually limited by the amount of gfx memory.
For a FX5200 with usually 64MB or more there is enough memory to display
all resolutions with millions of colors.

I currently run at 75Hz and have become so accustomed to it that 60Hz is now
unbearable to be.

Maybe with a CRT. With a TFT (which isn't a line scan display like a
CRT) there is no flickering and 60Hz is more than sufficient.

Is it true that connecting via DVI allows greater resolutions and refresh
rates?

No.
