Here is a benchmark showing both framerates and power consumption at the wall in Watts comparing a stock PS3 RSX running at 500MHz Core / 650MHz RAM vs 600MHz Core / 750MHz RAM.

Conclusion: The increase in temperatures and power consumption is negligible (less than 5%) compared to the performance uplift of 15%-20% across the board. As this game spends pretty much all of it's time below it's 30 FPS cap, the upgrade in performance is tangible during gameplay and can be felt even without monitoring software. The only visual artifact I noticed was a 'ring' appearing around phyco's face briefly during the cutscene, appears to be related to LOD's. Not sure if this definitely related to the overclock but not very noticeable either way.


Testing specs:

Ambient Temp: 23c on stock test & 22c on OC test.
PS3 Model: CECH-2503A (Slim)
Storage: 500GB 7200RPM HDD
Resolution Set on PS3: 1080p
Game Render Resolution: 1024x720
Fan speed: 35%

I tested the loading times from a cold boot and they were identical (well the OC loaded 0.3 seconds quicker if you want to be precise, margin of error stuff).
