Basically:
6xxx series
6800s come in Non-Ultra, GT, GS and Ultra. Ultra is too expensive, so it's out. GS is currently not offered in AGP, so it's out. GT is 16 pipes x 350 clock speed and 256-bit 1000mhz ram. 6800 is much slower than 6800GT since it's only 12 pipes and sports 128bit 700mhz ram. Advantages of 6800 series include ability to put 2 together (SLI) - not applicable to you, ability to support HDR (which X850 can technically do but games wont provide support for it) and PS3.0 shader support in games like Far Cry, Splinter Cell: chaos theory and age of empires 3. Also in simple terms, 6800 series of cards are better at games that incorporate a lot of shadows (softshadows, FEAR, stencil shadows, Doom 3, Quake4).
Pixel Shader 2.0 vs. 2.0b vs. 3.0
X800/X850 series
X850 series only have PS2.0b, so they wont have as good of an image quality in terms of shader effects in few select games. The problem is, 6800 series is simply slower in most PS3.0 games like Far Cry and Splinter Cell and in all games that support HDR. So you are better off taking X850 that'll produce faster framerates and sacrifice some image quality. Normally, I'd say PS3.0 is important as both X1800 and 7800 series fully support it, pushing the direction for future games. But since you plan on upgrading in 1 year anyway, this won't make much of a difference imo. If 6800GS was available for $200 in AGP, it'd be a really good card to go for. But it's not.
With FEAR, you need to turn off Softshadows on X850 cards or they'll tank. But once you turn it off (which wont affect image quality much), X850 should be faster than 6800 cards.
X850XT PE vs. 6800Ultra (that would be similar to comparing X850xt vs. 6800GT - just downgrade both scores by 10% or so since that is the advantage X850xt pe and 6800Ultra hold over their lower siblings)
Basically, X850XT will be faster in FEAR, COD2 (although for both of these, faster still doesnt mean playable

), Far Cry, BF2, HL2.
6800GT/Ultra will be faster in Doom 3, Quake 4, Chronicles of Riddick, obliterate X850 in AOE3, and other open GL games like Pacific Fighters.
What you want to achieve, ie. playing at 1600x1200 is simply not possible with any of these cards, maybe not even the latest cards.
COD2 - 1600x1200 no-AA/noAF
FEAR
