Precision/Afterburner/Rivatuner are all great, the GTX460 rruns pretty cool, so the stock cooler would be perfectly adequate.
Though if you can get a ASUS DirectCU, MSI Cyclone/HAWK, Zotac AMP! or even a Gigabyte dual fan model it will birng the temps down over stock.
Ya, but Evga was cheaper :P, but I'll shop a little....I found the Gigabyte GeForce GTX 460 Fermi 715MHZ 1GB GDDR5 2XDVI Mini-HDMI PCI-E DX11 Video Card at 229
I have a 9800GT right now, and when I OC it, my screen makes funny things (when under load), like if it wasn't refreshing fast enough or something....
