So, after all this talk about RGB, I have found myself curious about it. I kinda feel dirty for saying it.

I bought a decent 17" Samsung monitor over the weekend at a thrift for a paltry $5. It's a fairly nice monitor, as I've used one before, and I noticed that it has analog RGB input on the back. I'd assume I'd be good to go with it and not have to buy anything else? I'm not wanting to jump off and go with anything more expensive, upscan/etc. It's a cheap monitor and I'd like for it to be a cheap RGB solution.

I'd want to try these machines with it:

Atari 2600
NES
SNES
Genesis
PSX
PS2
TG-16

What's needed to get this things up and going, other than cabling? I don't think a couple of them will do it anyway, but I really don't know what I'm talking about here.

Am I really going to notice that much of a difference, honestly?

I'm sure that these questions have all been asked before, but it's a real chore to have to sift through 5+ pages of forum search results to find it, let alone the rest of the intarweb. I did check gamesx.com, but it's kinda hard for me to swallow all of that info at once.

I thank you all in advance for your input!
