Have had ample opportunity to test the system. Here goes the list of observations -
1. System is good. Fast and dependable. Everything is very compatible.
2. CPU temps are cooooool at 25C / 77F at low loads. Havent seen them go beyond 30C / 86F on some loads. Hevnt done any serious load testing.
3. changed my computer case from mATX compatible to a ATX one and that reduced the CPU temps by about 6-10C. The temps mentioned at 2 above are with the new case.
4. Mobo temps (I believe this is the temp of the Chipset on the mobo) seems to be a bit high at 47C / 118 F. Checked with one of my best friends - search on google - this seems to be a problem with the P5 series of Asus mobos. potential problems include close placement of the sensor to the chipset. People have tried stuff like playing with the heatsink and replacing the thermal paste for the chipset with Arctic Silver. That has brought down the temps by about 6-8C.
Point 4 seems to be my only concern. So would definitely recommend the processor (its a devil, a likeable one) till Pynryne comes out.
Any help on reducing the mobo temp would be welcome. Dont ask me to replace the thermal paste on it (I burnt my previous processor while replacing the heatsink
I got some external help with this build).
