If not, does it work for component? I have those cables too but know nothing of component quality (have never used it).

Just to clarify a common misnomer:

120hz does not equal AMP.

All incoming resolutions are displayed at 1080p @ 120hz. Frame interpolation ("AMP") is available because of the 120hz frequency... but AMP can be turned on and off -- 120hz can't.

120hz does not cause lag. The processing of the signal is what delays the video, and the frame interpolation of AMP uses the most processing, adding the most lag.

"Game mode" on this set turns off most processing of the signal, eliminating most of the lag.

The normal operating mode of the TV is 120hz. AMP off or on full does not change results. The only way to play without lag is to use the 60hz options of PC mode or VGA. Entertainment mode "game" lessens lag but does not get rid of it. 120hz represents this TV's ability to double a 60hz frame rate. It is not a native 120hz device and can't accept true 120hz signals as far as any tests show.

Sorry if this is the wrong thread to ask this in, but I want to have the best option for my vga or component connected xbox 360. I am assuming the xbox would look and play better on the 650 than it would on a 550. Of course it would not hurt if I had these unused features (120hz and AMP) for feature investments

Done and Done.

I have 2 hdmi cables from mono that were like 4 bucks a piece, work just fine. Hopefully this el cheapo vga adapter will work just great too!

I'm thinking about getting one of those, just to try it out.

what a shame, if thats true. Oh well for 12 bucks shipped i can at least get a feel for what vga will be like and go for the M$ official ones if i need/want to.

One thing to remember while in vga or hdmi2/pc that it is on the blurry side some like it some hate it for gaming. I hate it but even though the sharpness is at 20 or 50 depending on what mode is being used that its like if it's running with edge enhancement off with sharpness at 0 or worse when you compare it to custom setting with the above mentioned change.

I also noticed more and more that 50 or 20 sharpness while in hdmi2/pc mode that there was no difference. In custom setting and move it from 20 to 50 there is a difference. So if you noticed it kinda of washed out and blurry that's how it pc mode looks its not the cable.

That's why I said to try out game mode and pc mode and see which one looks better to one's own eyes for a certain game that is being used. Many neglect game mode because backlight cant be changed but it could changed by the Energy Saver Mode lol.

Halo 3 and Call of Duty 4 looks better in Game Mode with Energy Saver Mode at low or medium than using HDMI2/PC.

SuperStreetFighter2 Turbo HD Remix looks better in HDMI2/PC than Game Mode with low or medium energy saver mode. It depends on the game is what I noticed, but i dont notice lag so it dont matter i use my custom setting anyways lol...

Currently it's too dark and I don't expect the HDMI cables to brighten it up but it should clear everything up a bit. Either way I plan to go the HDMI2/PC route because of the ability to adjust the settings.
