The GPU is definitely weak; you can get something much more modern for around $50, maybe less on a good sale or rebate. As for the 80Gb hard drive...are you sure it's only 80Gb? If so, you're going to have a tough time fitting the OS and much more than a minimal install of Trainz on it as the OS may eat about 1/4 of that disk. A memory upgrade would be nice if you can do it, since the ability to use more than 3-3.5Gb of memory is the only major advantage of a 64-bit OS.
I'm curious to know the maker or motherboard of that machine: The components make me wonder about the age and upgradeability of it.
Hello again,
the idea is to start with the old PC (my current -ancient- desktop PC is an AMD Sempron 2.5 GHz, with an AGP Nvidia 5700le card, and running Linux on a 80 GB disk).
The motherboard is this: http://www.msi.com/product/mb/P965 Neo-F V2.html - it supports up to 8 GB.
My idea is to start with this machine, then upgrade the RAM to 4+ GB, and later to a card like GeForce 560 (after selling the GF 7950 GTX), finances permitting
(the power supply is 550W, so a single-GPU card should work easily).
My main computer is a laptop one (which I recently upgraded with a 500 GB 7200rpm disk).
In the desktop, I do not expect to use much more than the OS and Trainz in the 80 GB disk. Maybe I'll upgrade later to another disk, but I feel that 80 GB is more than enough.
Cheers,
N.F.
