Better off with 19" LCD, or S-Video standard def. TV ou

I'm building a PC to cost around $2000, including LCD if need be. I've got a good LCD picked out for $300.
So this means:
I can either get a $1700 system with $300 LCD, or
$1900 system with $100 for TV tuner, remote, windows media center, etc.

With the $1700 system I'd be 'limited' to a 7800gt. with the latter i could go as far as a x1900xt.

I'm wondering, is the drop in resolution caused by S-video connection to a standard-def TV worth sacrificing the high-res gaming i could get with an LCD?
ive been debating for some time now, some help would... help.

... you cant game on a tv..

Are you mad? Get an LCD.

you have a ways to go to see real hi-rez graphics, no console even comes close, unless you have a dvi,hdmi tv and an xbox 360, and I don't think that's as good even.

Oh yeah, svid will do up to 525 lines horz rez, not sure what the vert is, standard NTSC output, same with component video, having a higher rez on the computer will sharpen the image simply because of the increase in detail, kinda like interpolation in reverse I guess. Analog TV's work a little different than monitors so even when you put an 800x600 image on a tv, it scales it down to the 525, if the tv supports more lines, my toshiba is 700 or something, it stretches from the NTSC standard, it doesn't give more detail, but it keeps the image consistent on larger screens so you don't see black lines between pixels. Anyone correct me if I said that wrong!

I just found this, it's a little different:
