is it possible to upgrade my CPU?

It might be possible (if Dell didn't solder the CPU to the motherboard), but it's not easy, would void your warranty, and be pretty expensive to upgrade to anything worthwhile.

If you wanted a better CPU, you should have picked one out when you bought the system.

You could easily upgrade to an i5 but the difference is not going to be that great, particularly at the expense. Compared to what it would have cost you when you ordered it you are going to spend a fortune. Personally I think you have the sweet spot. The low end of the i5's are the same base speed you have with a relatively low turbo speed. The next step up has a small increase in base speed and a pretty good turbo, but how often are you going to be in turbo, not to mention the cost is huge.

I still haven't found a definitive answer whether the i7's will work in the motherboard or not but the thermals would be of concern as well.
