Choosing a motherboard and Processor. Lots of questions!

[SpringNite]

Hello guys, i'm going to change my motherboard and my processor. Because before i used socket 478 Asus P4P 800 SE and Intel 2.8Ghz. So now i'm going to change my socket to LGA775.

I wan to ask a few questions.
1) Can i change my socket from 478 to LGA 775? I means buy a new one.
2) My ram is Pc3200 512MB, if i change my socket 478 to LGA775, am i able to use back my PC3200 512MB?
3) For gaming and LGA775, AMD or Intel better?
4) And my graphic card is Gecube X700 256MB, am i able to use it in socket LGA775?
5) Just now i did a few researches, If i'm able to use Gecube X700 256MB, can i choose ASUS P5RD1-V Deluxe (Intel LGA775 Pentium 4 CPU, ATI RADEON XPRESS 200 Northbridge, Dual-Channel DDR400/333, On board TV tuner, 1394 Interface, Serial ATA RAID).

Every bros, please help me out of this questions! Because i'm urgent to buy it and please give me a correct answer for each question. Thank a lots!!!

1)IF changing to a different socket Motherboard you would need a NEw CPU

2)Yes

3)Its been proved many times, AMD for gaming, and Intel for multi-tasking, altought, most times its not a big difference between the two. If your going for AMD look at socket 939

4)Just make sure the motherboard you buy is able to accept PCI Express cards.

5)... dont have any experiance with Intel's side of things
