Some upgrade advice please?

[startrekmike]

Since you run at a fairly high resolution, should I expect high/medium settings on my end due to my much lower resolution?

To be specific, could I possibly expect to have medium to high settings for land textures?

I know that it is tough to guess when you don't really have the same system that I do, I mean, I need to upgrade the card very badly anyway but I just don't want to get my hopes up and think that I can have land textures that don't look like a blurry impressionist painting when it might not be possible anyway due to poor texture optimization.

The buildings can stay on low for all I care, they look good even at low (perhaps that is part of the problem), I just want some nice looking land and a smattering of tree's


Thanks so much for your help so far!
