My rig so far only lag if  there are tooo many unit appear 

So you are not from KL ehh.

Heh same here, but still playable.

I am from KL...... I'm just studying in AUS .........

I gave this a try, and i lose at the 1st mission on all three factions. I could have sworn the AI was cheating, the base was empty after i killed most of the defenses and patrols then all of the sudden hordes of tanks,bots, fighter jets, bombers came into the screen, lost motivation there and quit to desktop. This was on easy, maybe i just suck at it...now im not too sure i want to buy the full version, haha.

If upgrade to C2D @ Quad Core will teh lag gone? (After patching or etc... have been done) 

After download 1gb demo and play, this game is [P.O.S[.

SC has very bad game engine experience, visual quality not that good and the polygons still visible. I run the demos on 1024*768 default with little amount units.

Even AOE III & Codename Panzer runs max detail and very well on my 7600gt. Bye2 SC, I wont looking for you.

I think upgrading the RAM, and GC will do.

I am still using AGP

running on :-
AMD64 3200
RAM 3gb
Seagate Sata 320gb
X800XT PE 256MB

Who want this game cheat de tell me

Ahh nowonder you are getting it in Aus but why do u need a friend to get it for u in Aus?

The downside is that Supreme Commander can bring the most modern PCs to their knees. Since the game is keeping track and simulating hundreds of units over such a large area, it doesn't take much before the frame rate will start to stutter. On our test machine with a dual core CPU and 2GB of RAM, we experienced slight pauses on the humongous 81k-by-81k map. On smaller maps with a larger set of AI opponents, the action slowed to a virtual crawl as the system strained to keep up with the action. It's doubtful that a PC has been built yet that can run Supreme Commander's largest map with a full set of AI opponents at high graphics detail. Thankfully, you can adjust the graphical settings quickly and without having to restart the game, so if the battle starts to chug, you can simply go to the options menu and lower the visual detail to smooth out the frame rate.

I believe you didn't read my previous post properly........

I said it would be troublesome for my friend to get the game for me in KUALA LUMPUR (even if the game is cheaper there)..........
