If you feel that your gaining too much fat while trying to bulk then I don't think you have to worry about 60 minutes of cardio a week. If anything it might be beneficial. I'd prolly toss in a bit of low intensity stuff while bulking if I didn't have a job that I get alot of exercise while doing.I'm not saying go out and run a marathon but I don't think what your talking about is gonna be detrimental to your gains in the long run.
PS Don't forget its normal to gain a little fat while bulking. Remember to look at the big picture.
