Here I go again.

No seriously, I'm interested.
I'm interested in the baseline and how game developers decide on minimum requirements.
According to 1C and Ubi the minimum requirements to run CloD is
Windows XP SP3
Intel Dual-Core 2.o GHz
2 GB RAM
ATI 4850 512MB GDDR
So for this machine to run CloD I guess all video settings are set to lowest possible (uuggglyyyyy) and spawnhumans=0 and all other bling bling is switched off in game and on card.
So my question is, with a minimum requirement system, will I be able to participate in 128 online players battle at the resolution of 1920 (4850 max res) with an avg framerate of 25 or higher or...
...am I only able to fly solo over water without clouds at a resolution of 1024 and a framerate of avg 10 - 20?
In short, what do 1C and Ubi mean with running the game/sim in regards to fps and resolution??
Anyone who has this system that can try it out?
