For most modern games it's the GPU, not the CPU that are important. There's .2Ghz difference in the CPU but they are otherwise the same.

So, no, the slightly faster CPU will barely make a difference. Just be aware that even on the newest intel graphics, you aren't going to get great gaming performance.
 
Sorry I really meant the 4288U gets a 100Mhz GPU boost compared to the 4258U GPU. Either way, thanks Pervysteve. Think I'd go with the USD1499 model.
