    Hi Mark the grease I used was made by DYNEX and was hard to find. 
Not sold in the typical computer section of a store.

    I did also buy a PCI-Ex board that has a 7200 nVidia chip and it has 
a GIANT heat sink! The entire card is covered by it. I installed it and 
hooked the monitor to the old VGA output (it has 2 other output plugs).

    It came up working and I switched to high visual effects and it has 
been running for 8 hours now and is working fine.
