A lot depends on how frequently you collect your data. If you gather performance data for ten services on each of those 300 hosts every minute you're probably asking for trouble, but if you only gather a couple of metrics from each host every 15 minutes, that's not likely to break anything. If you add PNP to all of your 300 hosts and your Nagios server struggles, I'd definitely consider whether you can reduce your check frequency and still have all the information you need before messing about with bulk mode. I have implemented bulk mode, but only on the local server. My four-cpu system is coping okay with 1500 or so rrd files, but a lot of those are updated using checks at 5 minute, 15 minute or even less frequent intervals. I don't think implementing bulk mode locally made a great deal of difference but expect that offloading the processing to another server would make a huge difference if I ever get around to doing that. If you're worried about performance, I'd also maybe look at how efficient your plugins are. If you're running a large number of checks at frequent intervals using inefficient plugins this can have a marked detrimental effect on performance.
