If you are looking at getting the 4890 I'm sure you wont be disappointed but there isn't really alot of benchmarks for it yet since it just was released. Not many people have it yet and it hasn't really been reviewed much. So it is hard to tell how much better it is than the 4870 right now but its really not that much more expensive.
But If you are looking at getting one of the others suggested as was stated both the 4870 and the GTX 260 core 216 perform VERY similarly so basically it comes down to a few other things.
1. Which one is cheaper
2. Do you plan on either running SLI or Crossfire with whichever one you chose
3. Does your Motherboard support which ever one if you answered yes to #2

The HIS 4890 1gb is actually cheaper with MIR than the HIS 4870 1gb right now...
But the 260 Core 216 is DIRT cheap also... Tough Choice and kinda hard to pass up at under 170 bucks IMO...
