MD - None
DO - Terrible
No help at all. Undergraduate and graduate GPA's are calculated separately, and viewed differently by adcoms (MA/MS grades are notoriously inflated). You will also have a problem getting acceptance into many non-medical graduate programs with your GPA.
You need to rehabilitate that uGPA; that's why startswithb asks your credit hours. You need to take undergraduate science classes, and probably retake all of your MD/DO prereqs, and try to get that GPA up. Improving your GPA is probably more realistically possible than increasing your MCAT to the point that schools would overlook your GPA. Regardless, 3.0 uGPA/3.3 BCPM GPA should be your targets. It's going to take a while and a lot of hard work to get there. If you want to be a physician bad enough, others on here have made similar improvements and gotten acceptances.
