Not to mention that the 4870's memory bandwith will be higher than the GTX 260 if its GDDR5 Memory frequencies are high enough and will have overclockable shaders just like the GTX, so the 260 will not be amazingly more powerful.

Both cards should overclock well and though Nvidia has historically provided more headroom, this will be the first batches of the 200 series from Nvidia while ATI has been tinkering with the R600 based architecture for years now.

Hence my comment in the preceding post

You forget that GTX 260 will a lot more memory and games like STALKER and Age of Conan can easily eat up over 700MB with more to come. By the fall 512mb won't cut it for highest texture quality.
