[Solved] Can My CPU be upgraded

Ok so I have a dell dimension 8400(You dont have to tell me I know they are not good for upgrading). But anyways its getting a lil old and I was thinking bout upgrading it then in a bout a year or so I wanted to give it a go at a custom built machine. Basically what I am working on now is adding RAM, a new video card, a bigger faster hard drive. Then I started Looking at upgrading the CPU and found out that it might not be possible. A friend of mine told me and I quote "The Pentium 4's were at the end of one Socket generation (478) and the start of another (775), and the CPU you have uses the latter (going off the 2MB L2 cache), meaning it might be possible to upgrade to a Core 2 Duo (higher end Duos and any Quads will probably be out of the equation, however)." So I was wondering if this is true and if so can anyone point me in the right direction of a Duo that would be in "the equation". And if not maybe a mobo that would be compatible and again I know that this is a long shot from what I have read. But anyways heres some specs and any help would be appreciated.

I recall reading that a c2d can only be added to a board with an intel 965 chipset and above. I'm fairly certain this is the case, but can anyone else confirm that?

Supports C2D.

If you are looking at adding more RAM, a Video Card, a Hard drive and a processor, all of which you are spending money on an old outdated Dell system. You will still have an old outdated Dell system. You likely will need a PSU if you upgrade to any mid-range video card as well.
Now, if you are going to do all that, you realize that all need is a motherboard and case and you have a completely new build, without being limited to buying old slower parts that will work with your Dell board. I think I would try to come with just a little more cash and move in the completely new direction rather than dumping a wad into the old machine. It won't cost you much more than you are planning on spending now, not much at all.

yes everything is moving to ddr3

That's right. 'Xactly.
