I want a good and reliable motherboard.

I want at least a 3.0 dual core processor with some power behind it. I currently have a AMD dual core 5000 with 2.60 GHZ.

I want to go with either the newest NVIDIA 8800 or the latest ATI whatever that is. I have a NVIDIA 8600 GT with 256MB on it now. This system is going to my Son.

I want 3GB memory. I would go to 4 but that would mean a 64 bit OS right? I am unsure how practical that would be so i figure 3GB would be good with of course a couple other slots incase i do wish to move up later.

I want to ONLY run Windows XP pro.I do not like Vista tried it disliked it will change when I have No other choice. I would like the system to be able to handle that switch at a later date a year or so from now when they finally get it right.

I also want a top of the line power supply and whatever is needed fan wise to keep it cool as I do run my system a lot and heat was what took out my last machine. i do Not want to skimp in this department yet I have no idea what is needed and best to have.

I do not care for manufactured systems that are full of crap that is not needed. So any ideas. Still unsure if I will go to a local shop and have it done or go though a place like Cyber power or another if anyone has recommendations that would be great. I just want to have the information for what I need and what works well so I am not going in to this blind. if I go the local route which saves shipping and all that nice stuff I will likely have it done here. http://www.tcponline.com/Index.htm This is the place I got this one I am using now. They were a pretty nice shop and for what I could tell prices were fairly ok. They sell the systems but unsure if I can just build it to my liking with them.

My budget is 1000.00 to 1500.00 maybe a tiny bit more. I would rather not get close to the 2000.00 mark if I can stay clear of it

Thank you for any and all help on this.
