Q. I heard it's lower then 600 hz. If this is true, what's the point of buying a tv that advertises 600hz?
A. Haha, yeah it seems odd, doesn't it? What it is though is an apples and oranges thing...maybe apples, oranges and lemons.
The 600hz doesn't refer to the content, it's about what the screen displays (even that is too simple an explanation, see below). So to answer your question first, things shot on film and animation are usually 24 frames per second. Traditional video is about 30 (NTSC regions) or 25 (PAL regions). The hdtv standard goes up to 60 or 50 fps.
The refresh rate on the screen is how many unique images it can show per second. In this case, it's 60 fields. But Plasma tv pixels don't just come on and stay on (as lcd pixels do), they flash. So when plasma manufacturers advertise 600hz, they're saying each field is flashed 10 times. It's called a "sub-field" rate.
So the real feature is that each field is flashed so fast that you won't perceive flicker. Movie theatres do the same thing. If they just showed 24 fps, it would flicker terribly so they show each frame 2 or 3 times (24fps x 3 = 72hz).
I don't know how many sub-field flashes you need to eliminate perceived flicker but 600 is likely a lot more than you need (so if we start seeing 1200hz, I'm going to roll my eyes :) )
Manufacturers probably started advertising sub-field rates to make it sound better than 120hz lcd when they're not really describing the same thing.
Here's an article that explains sub-field rates in more detail:

What type of lcd to purchase?
Q. i am planning on purchasing an LCD HDTV $400-600
i would like to know what brand to consider just for watching tv/Blu-ray movies what do you recommend?

A. Right smack in the middle of the price range, look for a 32" set from Panasonic. The TC-L32C12 to be specific (or the TC-L32X1, also a great option). I think that is one of the strongest options for you in your budget. It would deliver really good image quality for you. If you can stretch the budget another $100, right now on sale at Best Buy is the TC-L37X1 for $700.
Alternatively look to Samsung and Sony in that price range and you should get a top notch TV still. Again look towards the 32' range. I think that's about as big as you should go on that budget to maximize quality. Some models to consider,
Samsung LN32B460
Sony KDL-32L5000

What kind of computer build would I need to do it all?
Q. My boss (the wife) has authorized me to buy a new computer. I am deployed overseas, so I usually download TV shows from iTunes or Zune to watch on TV. I also like a few online games. I have a computer monitor and I have an HDTV widescreen that I use to watch TV shows connected to the computer. What I really want to do is get a computer that is much quieter (hate to hear the sound of my fan during quiet scenes), can handle me playing online games on one monitor via my cable connection, playing a movie or tv show from my hard drive on my other monitor, and downloading large files over my wireless connection. Even though I am a gamer, I really don't feel like I need a top of the line computer. Looking to stay within a budget of about $5,000 not including a new monitor, but including some passable speakers. Is there a build that can do it all? No problem building my own. Any suggestions?
Bah . . forgot one thing. Want it to be able to record TV shows as well.

A. You have a budget of $5000 for a computer, not including the monitor?
That is a hell of a budget. You could get a machine that makes every gamer out there drool with envy by spending that much.
Also, why not just use your HDTV for the computer monitor? It is probably fully capable of being the monitor.
I would suggest one of the Core 2 duo processors, probably the x6800 Kentsfield core for around $1,300
Then 4 gigs of corsair dominator 1066mhz for $430
Then the ASUS striker extreme 680i motherboard for $319
3 Seagate barracuda 7200.10 750gb drives in a raid 0 array for about $600
A Lian-Li pc1100 aluminum sound-insulated case for about $300
2 XFX 8800gtx's in SLI for another $1100
Then a Thermaltake Toughpower 1000W power supply for $329
Let's see... where are we at here? $4380
That leaves room for a ZALMAN Reserator2 Water Cooling System for $339 plus an extra GPU water block for another $40
That leaves just over $200 for the Optical drives
You could drop one of the video cards and get a Lite-On Blue-ray drive for about $475
But that is your choice.
