System 2 is a better system although the Gigabyte board does have a good track record.
The 2nd system can be upgraded later to take the AMD Phenom Quad Core processor as the board is an AM2 board.

The 2nd system also has a better Power Supply. 420w is not enough for ANY current AMD processor, especially when paired with a high end video card.

I don't know what prices they are quoting, but as a Computer Store Manager (Part Time) I can tell you that System 1 is ALL OLD equipment and out dated. System 2 is much more current and can be upgraded for a lot less.
