I heard in an IGN preview that it's very scalable (i.e. if you tone down the graphics settings it'll run on anything). They were playing the game on a gaming laptop and it ran great.

I am going to go out on a limb and say low is the best you can hope for I am afraid, you are barely scraping the barrel on minimum with your CPU and GPU. 

It says you have 2 CPUs because the Pentium 4 chips have a feature called Hyper-Threading that allows a second virtual core, slight performance boost in some applications but no ware near as good as an actual second core, you can read more about it here http://en.wikipedia.org/wiki/Hyper-threading.

Left 4 dead and COD games can run pretty good on most pc's so i dont think u should use that as a bench mark. Same thing with world of warcraft, u should atleast be able to run that game at full settings(ultra) because its not very taxing at all.

In addition to this being a new game, so im assuming it requires better specs than wow does, as well as it being more action orientated, lag is the last thing u want as the delay will make things worse. And from what u said(wanting to run it on medium /high settings) i would recommend a few upgrades.

That being said i have not played the game or the beta :( so im just giving u my opinion in general. I have a better spec pc than u and i myself woudnt risk getting it on pc :)

Oh yeah if u let us know what resolution u play your games at, that would be helpful too.

i've got a pretty decent computer but even i dont run my games on 1920x1080. I go for maximum playability so i usually have an fps of 50-70. even if it means i have to go down to low/mid whatever and use 1360x768

SRL is a crap site. It claims I can't run:

Left 4 Dead

The Orange Box

Star Wars Battlefront

StarCraft II

GTA: San Andreas

Star Wars Republic Commando

Halo: Combat Evolved

And I can with my crappy onboard graphics. Because I'm a fucking boss and the Vista OS is my personal bitch. The site just isn't reliable at all. If you know nothing about computers, then it's okay, I guess.

As for you, you've got a dual core clocked at 3GHz and a pretty good graphics card. You're fine with running DCUO. If you are running Vista, I recommend turning off some stuff to make game playing more smoothly. And since I'm nice, I will even link you to a guide to make Vista run more efficiently:

You also might want to turn off some background stuff like anti-virus software and pretty much everything that is not necessary to run the operating system. Then you should be able to run it on high.

It also still helps to open Task Manager and close all non-essential processes.

your card is actually about the same as a 3870 but slightly slower. 

It all depends whether the minimum requirements they released are conservative, accurate or overly optimistic...

I say good choice, atleast u know ur game will be working now :)

I'm actually surprised people are having problems running this.  My home PC isn't anything amazing but I'm able to run it 1900x1200 with all the highest settings and don't notice any problems.

The real odd thing is the settings defaulted most everything to normal and when I changed everything to high I couldn't even notice a difference.  I played this afternoon on my work PC that should still have everything on normal and I didn't notice any differences at all (in fact, it ran a little slower but that was problabmy because I had many other memory hog programs running).
