Can my computer motherboard support higher than 2tb?

Hi i am looking to upgrade a hard drive of mine from 1.5tb to something bigger like 2.5tb or 3tb. I'M wondering if my computer will support anything higher than 2tb? I'm running 1.5tb and two 2tb hard drives right now. I don't want to waste money if my computer won't support higher than 2tb. If my computer does support higher than 2tb what will i need to get one to work? My motherbored is
Intel DQ965GFKR S775 mATX Motherbored
Heres my computer specs
Windows 7 Home Premium 32bit
1.80ghz duo core
250gb,1.5,2tb,2tb
1gb ram
