The two cards have different architectures. It's quite possible to have two games using different features more intensively, and you'd end up with the ATI winning one game and nVidia winning the other.
You have to be very careful where you get your benchmarks too. For example there's a review on Anandtech that shows the HD 4870 1GB beating the GTX 260 Core 216 in 5 games out of 7 and tying it in one. Then there's another on Guru3D that shows the GTX 260 Core 216 beating the ATI in all games (a different set of games than Anandtech's). I'm not sure if the two sites are fanbois of ATI and nVidia respectively, or have incompetent reviewers, or it's just a coincidence. They are both generally very trustworthy sites.
If you're trying to decide between one of those two cards, I suggest you go those sites, maybe use Google to find other reviews too, and see which card is better for your favorite games in particular.
in any case the difference will be unnoticeable (1-2 fps) so please. and end to the "which is better 4870 or 260?" threads. whatever's cheapest and/or floats your respective fanboi boats.
Or as aevm implied, get whichever performs better in your games. I'm also with Venom on this. There isn't much difference between these cards, its not like one pounds the other in one game while losing all the others. The cards are more or less equals, you pretty much can't go wrong with either one.

What about heat dissipation, I mean which one runs hotter, presumably, you don't want to get one which runs hotter than the other considering both are performing pretty much the same?
^fair enough, and because of this, and the fact that the GTX has the same heatsink as the 280 but obviously runs cooler, it should be able to oc further than the 4870 can oc, and therefore opens up the gap in performance in games.
not CUDA itself (99% of us who bought a desktop geforce arent planning to program on it right?), but CUDA applications. like badabooms video transcoder and folding @ home support, and yeah physx running on CUDA.
and shouldnt the 4870 be able to oc further since its on 55nm?
Can anyone tell me why 4870's performance in NFS12(and race games like that such as dirt) is better than N's?
Shader power.
Dirt is an example of a game that has long shaders (100+ ops) and can benefit from ATi's design so more ALUs/SPUs can work on it, where it is not as reliant on the texture fillrate and ROPS, so it can use it's strength to it's benefit.
This doesn't show shader power, but performance of that shader power available.

Depends on the setup, both can OC but both can also be limited in that OC, so talking about OCing the card is an afterthought.
Cooling isn't the only thing, as you see here the GTX260-216 had it's voltage lowered versus the old GTX260, and this will limit OCing as well. So for both the answer would be to tweak the voltages to get more performance.
But really OCing doesn't really change the situation that significantly.
