I'm wanting to exchange my 9800Pro in my shuttle to my PNY 6800NU that is softmodded. How much higher are the temps on a 6800NU compared to a MSI 9800Pro with the green pcb and large heatsink/fan? My temps in the shuttle now are pretty hot and I plan to add another 512 stick along with my 6800NU so I am just wondering if it's a yay or nay on the switch. Thanks
