The Intel Pro 1000 are really nice nics. The ones you linked would work well because they are PCI-E. If it were just a PCI card I'd be afraid of the interface bottlenecking your connection.
Also, did you check your settings for that realtek nic and make sure anything like TCP/IP offloading was turned on? Your usage seems quite high. I have a linksys EG1032
that's in a little AMD athlon 1800+ 1GB ram pc running Server 08 and it can get to about 50% network usage before I run out of CPU. You probably have 10x the amount of CPU in that pc than what mine is, so it seems like something isn't setup right.
EDIT: Also look for Flow control for both TX & RX, and Checksum offloading.
well i got the Intel nic in the server now, CPU usage dropped by huge margin. realtek is currently disabled.
but before i did disable it, offloading for every option was on, but cpu usage was still high. problem you are describing is very similar to what i had.
