My puter knowledge is limited, bare with me......
I have an old gateway Pentium 2 PC(399 mhz, 192mb ram) that I use for internet use. The hard drives(ata 100's - 7200 &5400 rpm) are hooked up via a PCI ata66 card. Would I gain anymore speed by upgrading to a ata133 pci card? Are my hard drives even running at max speed with that older card?
I just need a little more power because Surfing the net is fine until I want to also listen to music,then things gets slower(I plan on getting more ram also)

pick yourself up a cheapp one

133 will give you nothing.
get more RAM if anything, but you are still going to have a slow computer. if you are running windows xp on this, you need at least 256mb.

Yes, Win Xp home. I will max out the ram(768mb).
Thanks duder.

Sounds like a footrest to me.

I suggest getting it to 512mb.
if it's not too much for the extra 256mb, go ahead and bring it to 768, but a 400mhz comppy won't really utilize that extra 256mb.
