I would like to install some more RAM in my system as I do a lot of multitasking with photos and audio files continuously being edited. Right now I have 512 but i want to make it 2 GB or 1.5 GB. What would be the best (read economical) option. I wanted to get 2 one GB sticks but the total cost came up to 10000. That is a bit too much ain't it? I was looking for something in the range of 5000. The dealer says that the prices are high now and that i should wait and i could get 2 gbs for 5k in a month or so. Is it true? Also my system has a Pentium 4 CPU 3.0 GHz . Can I atleast buy a 1 GHz stick and use it with my 512 one? I am completely clueless in hardware so I am not sure how to check if my ram is DDR or DDR2 or whatever.
