MSI TF3 7950 OC Temps @ Stock?

I just bought a TF3 7950 factory OC at 880/1250. When I installed the card, I decided it would be a good time to clear out my fans and filters on my Storm Sniper case. I even placed an additional fan where the HD rack is as I only have one HDD directing the air towards the front and side fans.

I play on a single monitor at 1920x1080. Ambient Temp is 25.6 °C.

It replaced a MSI Hawk 460 GTX SLI Stock setup. My temperatures with the older setup:
Idle (GPU1 = PCIe slot closest to the CPU)
GPU1: 42 °C
GPU2: 33 °C
Load (Looping Frost Beach 50x on Max)
GPU1: 72 °C
GPU2: 53 °C

My readings now with a single 7950
Idle
GPU1: 38 - 43 °C
Load (Looping Frost Beach 50x on Max)
GPU1: 74 °C

What will be my load temp in mind when I go ahead and OC the card?
