In a 5-minute polling interval of a 32-bit counter you can rate up to 109 Mbps before the small counter wraps and MRTG will graph inaccurate data. In a 1-minute polling interval of a 32-bit counter you can rate up to 546 Mbps before the wrap and blown graphs. Without 64-bit counters you will not likely be able to accurately graph a 1000 Mbps link unless that link never exceeds those numbers for the specified interval. Search the list for "counter wrap" and you will find dozens of threads on this topic.
