Well in your usage case ext3 is still well suited enough. Ext4 though is the superior filesystem, since it is more advanced in technical terms. Maximum file system size in ext3 is around 16 Terabyte, something not so far ahead now even more in homes. Ext4 has the maximum file system size of 1024 Petabyte. ext4 also uses extents, which ext3 has not - meaning file system checks are able to run faster. Erasing big files on ext4 works therefore faster than on ext3. It also tends to fragment less than ext3. ext4 has persistent preallocation when writing large files, meaning space is being guaranteed and most probably contiguous. tl;dr: ext3 should be well suited enough for your computer, but if you can reformat your hard disk drive, using ext4 will not hurt either and you gain some faster speed.
