How many EIGRP prefixes can a single 3560/3750 layer3 switch store?

There is a design question in front of us and customer has a pretty tight budget.
This EIGRP domain has about around 1000 prefixes, no VRF, no BGP. can a single 3560 with Advanced IP ios easily support and store those 1000prefixes without bringing up a high CPU process or do we need to think about a 3750?

The 3560 is capable of configuring up to 11000 unicast routes. So your 1,000 prefixes should be fine. Please click here for the datasheet on Cisco Catalyst 3560 Series Switches that contains the summary of all the product features.
