<prompt> Human: Im thinking of applying for a second credit card. Ive had my capital one card for about 5 years now and paid everything on time and am never late with the bills. The problem I have with it is its limit 800 and it has no incentives.I basically used it to build credit as a young college student. Now that I have a better paying job and am able to sustain myself for a new home and car, what card companies should I look into? Specifically which cards?  <response>: I would see about a credit line increase. I had my Quicksilver for maybe a year and requested an increase from a 500 limit. Now its at 4300.
