If you love your job, you are the 1%. Most people dread going to work. A 10% bump in pay is not going to change that for the vast majority of them. Money is just money, happiness is a state of being. Not long ago, I was offered a 50% raise to leave my senior position at a small company to go work for a much larger one. Negotiations went well until the very end. In the "afterhour" when it was apparent the job was mine, I happened to ask about the desktop. Being a senior employee at a small company, I am accustomed to having vast flexibility. The norm is two desktops, one Linux and another Windows for testing, with a trio of monitors, plus a Mac laptop so all the major platforms can be tested. I was informed they run Windows XP, IT evaluates ALL hardware requests, and that is that. It was then I realized that trading guru status in a small company for being just another random coder at a large corporation would require a huge revision of expectations. In the end my family helped me decide that time with them (work at home now), happiness with my day to day computing experience, and overall flexibility was worth more then a 25% raise after taxes and commuting expenses.
Your situation is yours however, good luck, and I hope it works out well for you.
