Hi there people, this is my first thread

so sorry if anything is wrong! Ok here i go
I shall be getting my Sharp Aquos Aquos 37" Widescreen LCD (LC37XD1E)
http://sharp.co.uk/Product.aspx?ID=1108
Ive heard from a friend of mine, that it does not have direct component input instead it comes with a converter to VGA. What shall this mean in terms of picture quality?? Iam i going to loose any, iam sure that i wont get 1080p as the component cables dont support this. However shall i still recieve 1080i??
an some please post an image of what the converter looks like!
Another question i have is with my PC. I am currently running a geforce fx5500. Iam waiting for my quad core system with Twin 8800's to come. Which is gona be a mouth!!! Would my PC for now be able to support DVI - HDMI. The graphics card does have a DVI port!
If it does can someone please give me links to cheap DVI - HDMI cables, but one with good quality, but not dear!!
Also does the TV have picture in picture??
And finally lol, can anybody post images of the TV, menu systems, with an Xbox 360 connected, PC Connected. Connection views of the TV, MOST IMPORTANT!!!!!!!!
Thanks for any help you can give me guys!!!!!!
