I've got the platinum revison 2's and they're great RAM. I don't know why they want you to buy something else. I also don't see any problem with your power supply, its a good choice.
If that monitor has a problem with lower resolutions, you may want to look at this Viewsonic one:

I have it and have 0 problems with it, works great.
