In order to compare images from two cameras, first use a tripod to shoot the same exact scene, using RAW. This will produce two RAW images with different pixels densities.
Then, to compare those two images, you have to normalize the two images to the same pixel density. This means you have to downsize the larger one to make it the same size in pixels as the smaller one before you can make any comparisons. (Never upsize the smaller one, or you will reduce its quality. Upsizing creates artificial pixels to fill in the blanks, while downsizing simply averages pixels to form less of them.)
The D800 image has 7360x4912 pixels, while the D700 image has 4256x2832 pixels.
Use your PP software to downsize your D800 images to 4256 on the long side and use the short side default. (The short side will come out to 2840 pixels). You can compare them on-screen or output the images to the highest quality jpegs you can make.
View the two images side by side, and you should see that the D800 images are just as sharp as the D700 images.
Once you realize that the D800 is just as sharp as the D700, you can now appreciate that you have added resolution that you can use only IF you hold the camera more steady than you did with the D700.
The added resolution of the D800 gives you lots more cropping ability. You can often crop a person out of a group shot and make an 8x10 print that is crystal sharp - IF - you kept the camera steady enough!
