Upgrading my AGP x8 machine

Hi guys, great forum!

Here is my problem...


My current system specs:

Motherboard - ASUS P4S800 with a SiS648FX chipset (AGP x8) link

CPU - Pentium 4 2.8ghz


Graphic card - ASUS A9550 128MB link

RAM - 512MB (ddr 1)


Now, I want to buy a better AGP x8 card and I have been browsing through forums alot and I dont understand a few things. I know its pointless to buy a card that your CPU cant handle, so...

I was looking into these HD3450, HD3650 and HD4650 with 512MB or 1GB


My current RAM runs on 200 MHz and i was thinking of buying 1GB with 400 MHz


So basically
1) can my mobo which has AGP x8 handle ALL AGP x8 cards or not
2) which cards can my CPU handle (of the ones i was looking into)
3) I want to upgrade RAM so does this
mean anything to me since i want to put 400 MHz instead of 200 (how will that affect FSB ratio etc.)
4) my mobo has FSB 800 - is my CPU using all of it? (meaning can i get a better CPU on this particular motherboard)
5) hypothetically lets say i get a new card and new RAM do i need a new power supply (currently i got 400W) and will my PC overheat


PS. I'm well aware that this PC is obsolete, but since im kinda out of cash at the moment upgrading this peace of junk is the way to go and I just need it to run WoW, Warcraft 3 and maybe SC2 (ye i really just play Blizz games :D ), so ill just upgrade it till i get some $_$

PPS. please dont tell me its not cost effective, cuz i can get the components i want cheap.


Thanks for your help

More about upgrading machine
  1. 1. your mobo can handle any agp x8 card
    2. the P4 will not BT the 4650 so get the 4650
    3.just stick with DDR 200 cuz your ratio is already 1:1 so just add more DDR 200 RAM
    4. your CPU is running at 800 FSB, don't worry about changing that
    5. you probably won't need a new PSU even with the 4650

    hope this helps
  2. Save your money from upgrading and start planning to buy a new rig!

    thanks alot man...

    just one thing - what would happen if i would put ddr400?
  4. well it would offset the ratio and probably overflow the P4 which means your system won't be bale to start
