no i dont think it would be worth the upgrade....realy i think 2Gb is all you need at the moment.
are you gaming on Vista or Xp?
I have P4800 SE Motherboard, Socket 478 P4 HT 3.4GHz 800MHz, four 512 MB non-ECC DDR400 SDRAM memory rams each, AGP 8X ATI Radeon X 1600 Pro 512 MB DDR2.
Is it worth to upgrade 4G non-ECC DDR400 SDRAM memory rams? or is 2G memory rams is enough for gaming?
all you can get is 4g of memory on vista which is really stupid, thats like a laptop.
