D80 to D7000 or D7100?

I have a D80. And like it a lot, but (whisper it) don't use it as much as I would like to. I would class myself as a very average photographer, liking a bit of everything but being good at nothing.

I'm becoming more aware of the limitations of the D80, which is getting on for 10 years old now (although I have only had it about 7). I am thinking of upgrading and the D7100 has taken my fancy. But it's a fairly expensive bit of kit ... and the D7000 is a fair bit cheaper.

How much would I lose out on if I bought the 7000 instead of the 7100? I am aware it has a few less megapixels, but I rarely blow my photos up that much to notice. I am also aware that the 7100 has more focus points but am not sure how much difference this will make in real life. Is the focussing system the same other than the number of points? Things like a larger screen on the back won't make much difference to me, smart as they may sound and look.

For reference, I have a 50mmf1.8 Nikkor lens and an 18-20mmVR Nikkor as well.

All comments welcome, thanks.

Thanks for the answers. Either camera would be a chunky upgrade but the question is whether it's worth spending more on the 7100. The only feature that the 7100 has over the 7000 that would bother me is the focussing capability as I don't crop much (and I don't struggle with the low-ISO resolution of the D80 to be honest). I guess the question is whether I would save £150 or so by buying the 7000 and regret not having spent the extra on the better focussing of the 7100.

I shoot al the things you'd expect an inept photographer to shoot; holidays, social events, scenery, cats. I don't really shoot sports at all. The buffer size isn't an issue for me, although it's nice to know.

Thanks for the sample pics MysteryLemon. That last shot is pretty good for 3200iso. I know it's a small pic but that's impressive.

Maybe I should spend my cash on a new lens instead and wait until the price of the 7100 drops a little more ....
