Question about performance

I have the 13" unibody Macbook and ordered the new 13" with the 128 GB SSD. I was having some second thoughts about the SSD so I did a chat with an Apple rep and they told me that the 128 SSD is about 2 times faster than the stock 5400 rpm harddrive and it is actually slower converting DVDs to .mp4 files and about the same speed playing games on Windows. I was very disappointed in hearing this and thought I would get an all around noticeable boost in gaming and video editing. How's the real performance with the Air SSD since it is probably the same manufacturer. Also, will the new Air play games as well as my old 13" aluminum (2.4) since I understand gaming is GPU intensive and not as much cpu intensive. I am very satisfied in playing games like Call of Duty 4, Fallout 3, Mirror's Edge, Dead Space, etc on my current Macbook, but I may be interested in the new Air if gaming is about the same. Thanks!
