Mitch, ASIO is the way to go for low latency especially if you are using many soft synths like I do. While the "quality" of the ASIO drivers varies from manufacturer to manufacturer of your respective interface, IMHO the real key to low latency is setting up Win 7 properly. The biggest issue you may run into is running your computer with your wireless adapter switched on. ASIO and wireless do not play well together. Also, if you are using an external audio interface, which it seems that you are, go into the Win 7 Device manager and be sure that your internal sound drivers are disabled...no need to uninstall them, just disable them. If you want to probe further into Win 7 tuning take a look at this link: http://www.native-instruments.com/knowledge/questions/847/Windows+7+Tuning+Tips+for+audio+processing over at Native Instruments. The use of DPC Latency Checker followed by the use of the more specific LatencyMon will help you pinpoint your tuning.
