Thread: Is my pc worth upgrading?

LONG POST. I’m newb and got lots on my mind.

I picked up this pc for $35. i know basics about pc's like swapping components.

I built-in screen of CPU ID says. Feel free to inquire me no matter which about it or even take pictures of motherboard if u guys similar to.
And this is the specs i got from dell website when i put in service tag:

my questions are it worth adding another xeon?

What is the potential of this system? What’s the highest graphic game I can play? I would be happy playing crisis or any of the recent games. It says pci 16 xs, I just don’t know if it’s worth upgrading.

Is the memory good? It says 4 GB but when i go to properties on my computer it says 3.25 gb.Is that normal?

What can I do in excess of clocking wise? I never over clocked before so yea... im scared of it right now. Lol

present is a bunch of plugs in the back, and I know it has a raid setup which I don’t know crap about raid other then it’s a backup system..... Is it worth keeping?

The power provides I noticed is the entire base of the computer. Which got me saying wtf? u can see in the pic where the two fans are on bottom. Sometimes when I boot it says something about power low. i cant remember, it happens once a while. What’s so special about this psu setup?

Another thing is what are all these cards/plugs? The one under where the monitor is plugged seems like second video card based on it looks the same and cpuid said two. I haven’t tested or opened to look at it yet but I hope I have two.

Any input or advice I would appreciate. I know i got a good deal. My pc before this was a p3 850MHz back from when enforce 256 card came out over ten years ago. It’s a mind-blowing upgrade for me already. i usually play halo1 pc on it and gta: samp on it but low settings. I would love to play some games with high settings for once.
