Talon, you might have the worst sytem in the community now but until last April I had you beat. I was playing on:
Dell Dimension XPS T600
600 Mhz PIII
512 Mb SRAM
32 Mb AGP 2x/4x GeForce MX-440SE
Soundblaster Live! Value
2x120 Gb Hard Drives
Win98SE
I was also running frame rates in the 15-30 range running 512 textures, minimum object detail and 3 miles vis range which seemed fine to me as I had no other point of reference.
What always got to me was people on the BBs whining about turning graphic detail down in GV's being a "cheat". I wasn't trying to be gamey. It was the only way my machine could handle the game and I did voice my opinion that it was to help older machines run, not to cheat as accused by those more fortunate. Whenever a graphic update was coming I didn't whine but knew it might be the end of AH for me, at least for a while.
Of course, the only way you get a machine this old to run well is to keep it clean of adware, spyware, background processes, etc. and to do regular maintenence (i.e. disc clean-up, defrag, etc.).
I couldn't really afford a new computer either but finally bit the bullet as I knew I was hopelessly out of date. I had bought my old Dell in '99 for about $2000. Prior to that I had spent about $2000 on an IBM in '96. This time I built myself, again for about $2000 and this sytem is complete AH overkill (but I love it

). As a side note those systems at those prices all included things like monitors, mice, keyboards, speakers and even a printer and scanner with the first one.
If you can re-use your monitor, mouse, keyboard and speakers and build it yourself (build only the box) you can get a system that will slay what you are playing on now for under $400 (before shipping, taxes, etc.). If you can re-use your operating system, hard drives and optical drives you can do it for under $250 (before shipping, taxes, etc.). Now we aren't talking top of the line here but you should be able to run just about full graphic settings at strong frame rates.
If you'd like to upgrade and want me to assist you feel free to send me a PM.
BTW, I'm still using that old Dell as my word processing/e-mail/office machine.
