3. I assume you are talking about the same reasoning for getting Dual Channel kit vs seperate sticks : it will be the same situation i.e you have 1 bios with 2 (perhaps) different pairs ( DDR2-800 &DDR2-1000 for example). so the penalty in running the 2*(2*1GB) ram at the slowest common denominator is hard to predict.
4. BUT the PC performance vs RAM performance are 2 different things, and as #2 indicated , even a bit slower ram can be beneficial overall .
5. By itself , ram speed contributes not more than 1 digit percents to PC performance .
1. I'm using vista 64bits

2-5, I'm asking this because my sole interest is to anticipate any need for 4gb in future games like Crysis and take advantage of the low memory prices that we currently have on the market (I hear rumors that the mem price is going up becase they are reducing production)
