660ti vs 7870

Is this the Pitcairn-based 7870, or the Tahiti-based 7870? The former is more common. If it's Pitcairn, I'd say no. When the 660 Ti came out, it generally beat the 7870 in benchmarks, with the 7870 only pulling ahead in memory bandwidth limited benchmarks.
 
7870's aren't great for mining, I didn't think the gap was as big as 15% to 20%, but the 660TI is faster.
 
The 7870 XT/LE (tahiti) is worthwhile. It overclocks easily to match or beat stock 7950 speeds. However I wouldn't trade a 660Ti for a pitcairn ones unless you really want to mine.
 
7870s aren't bad mining cards, but 7850s and 270s are much better in terms of price/performance/watt. You can expect around 390-400 from a 7870, although I certainly would not recommend a reference card. As far as 270s go, they can easily get above 470. So, I'd wait until you get an offer for 7850 + $$ or a 270.

I really want a 7870XT or a 280x

I have WOW Mist of Pandaria Collector's Edition I want to get rid of as well.

For mining? Trust me, you do not want a 7870XT for mining... I just sold mine, it was a huge disappointment for mining performance, but a beast as far as gaming performance/OCing is concerned.

280x would obviously be a very nice upgrade, especially with mining in mind, but I don't see you getting that offer unless you add at least $150 on top of your 660Ti.

I'll get better khs than the 260 I'm getting (this is with an overclock of 100 on the clock and 123% power)
 
True, with the 7870XT you can expect a maximum of around 360kH/s. Each card seems to be different though, but that usually holds true for the majority of them. You would also be using a lot more power than a 7870/7850/270. 7850s are capable of pulling the same mining numbers as a 7870XT while using significantly less power.

I get 430k all day on mine. You'll be playing with settings for awhile though.
