how to select the right memory?

---

need your help guys on choosing the right memory.
1. Is 1G enough? I used my pc usually for dvd playback and manage pics. I sometimes play games.
2. What's with dual channel? does all new motherboard support this? How much improvement will I get if I run on 1GB running in dual channel than in single channel? 50% faster?
3. How to choose right memory speed.

i'm thinking of getting a core 2duo. why?

[Zirv]

for amd x2 ddr2-800 would be enough

for intel core 2 duo which are very excellent overclockers the higher the ram the better ddr2-1066

is 1GB memory enough for current use? ms recommendation is 2GB but my vista laptop runs well on 1GB.
