Budget Build 800-900$ need suggestions/commentary

Hello,

I have been looking at these boards for a little while and it seems like a good place to ask for some help

I'm a student at Virgina Tech and I had to buy a tablet PC when I was a freshman due to a school requirement, as you may know, tablet PC's are basically a business style overpriced laptop. well, after 2.1 years of having said laptop, the AC adapter port on the back has broken off the motherboard. I was considering building myself a PC for a while. I asked a friend who has been a little more up to speed than me on current desktop stuff what I could get for about 800. He came up with this

21.6” Widescreen LCD - $179.99

Now, I'm on a budget, and I already have a keyboard/mouse, so I probably wont get the cheapy microsoft one he suggested, and I pry wont get a floppy drive now that you can pretty easily boot from a flash drive.

I was wondering, is the processor he suggested halfway decent, and should i get more ram, I happen to have a copy of vista ultimate 64, so I'm not worried about an OS or anything

Also, I would like to play games with this PC, so I need suggestions on a graphics card, I think he mentioned an ATi 3870 or the like, I looked at a couple of those on newegg and they seem nice enough. I play the occasional Wow and some Supreme commander, HL2 and I would like to be able to play Spore when it comes out. (and any other games for the next few years)

I also do the occasional CAD work, and I'm fairly proficient with Inventor, so I would like it to be able to render that kind of stuff as well.

If anyone has suggestions or comments on the components, I would really appreciate any help I could get. I'm taking summer classes right now and I would like to order stuff/ get it together in the next 2 weeks, so I will finally have a functioning computer again

Thanks guys,
