The extra RAM might smooth things out in texture-heavy situation, but I can't imagine that jump helping a 5500 at all. 1GB is already a good amount, 2-4x as much as most people own. It seems strange that going from two sticks of 512MB to three sticks (usually slightly slower than two due to physical constraints) would let you boost your res to such a degree. This is assuming both setups played the same, tho, something implied (mistakenly?) from your post.
Second of all, why did you go from 800x600 (4:3 ratio) to 1280x768 (16:10 ratio)? Why not 1024x768 or 1280x960/1280x1024?
There are a lot of holes in your story, mister.
