Let me just get right on that, i dont have a job, im only 15 years of age, i make 35 dollars a week from poker. So yeah, let me just run out and buy a new mobo, processor, video card, and ram. So basically, a new computer.
Well, your memory will not work with a Socket 775 Motherboard and to find one of those with AGP Port at that is hard, in the end you will be spending around 180 US Dollars on new memory (a waste to go with 2GB if you can save a little more and get 4GB), E5200, and 775 Socket Motherboard with IGP (Socket 775 is facing the end of its life). My advice, save some more money or ask your parents for some cash in advance of future gifts or what ever and spend around 270 US Dollars on something like this:
ASUS M4A785TD-V EVO AM3 AMD 785G HDMI ATX AMD Motherboard

AMD Phenom II X3 710 2.6GHz 3 x 512KB L2 Cache 6MB L3 Cache Socket AM3 95W Triple-Core Processor

Crucial Ballistix 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333

If you are thinking about overclocking that E5200 you will need to buy an after market cooler for that, if you are not, there is no point to go with that processor. The Phenom II x3 710 will murder it if both at stock clocks, and you can overclock it too, you will get an extra core and you will use it on the AM3 socket (newest AMD socket) this will give you a better upgrade path in the future, you will also be using DDR3 1333 mhz with fast timmings and the Video Chip that comes with the Motherboard would be equal if not better to your AGP card, you can save some more money and upgrade the video card later.
I would like to know what PSU are you using right now, to see if it can handle all of this or if you need a new one.
Final words: You are past the point of when your old system needed and upgrade, if you go with old and not so cheap parts you will be facing the same situation all over again shortly, better to spend a bit more and get the best bang for your buck.
