There aren't compatibility issue but you won't be able to Sli two Nvidia cards where as you could CrossFire two Ati cards. Do you want PhysX? If not, go with the 4870 (or crossfire 4850, whatever's your preference)

Gist of it, right there. But worth considering two 4850's for budget reasons

From what I understand, they are pretty evenly matched, performance wise.

From what I hear, it outperforms the 4870. http://www.tomshardware.co.uk/charts...otals,795.html If I had to recommend a retailer, it would EVGA for their tremendous customer support, lifetime warranty, and their step-up program. |

They vary between games, settings, resolutions.. Its endless really and the fact that three different GTX260's exist doesn't help.

As far as I know PhysX is not too useful in gaming these days, maybe with time things will change but until then it's not so important to have PhysX in your system...
Physx is technology that takes care of all the physical calculations, if there is a Physx PPU on the system (Ageia PhysX card, GeForce 8 and higher GPU from Nvidia or a CUDA equipped GPU from Nvidia) then what the PHysX system does is, to take all the physics calculations from the CPU and it passes them to the PPU to be processed. This take load from the CPU to allow it to make more calculations and allow the games to run faster. This works ONLY IF THE GAME IS PROGRAMMED TO RUN WITH PHYSX!!!!
So, because many games don't support physx correctly, or they just don't support it, i'd reccomend you to pick the HD4870 1GB if your budget is tight, if not, then get the GTX 216

but remember, if you pick the GTX 260 you won't be able to make SLI because of the motherboard

another extra point to get the HD4870
