Update:
got Phenom II 940 as a christmas present
Updated BIOS for motherboard
Swapped out my FX-62 and insert the 940 Chip.
Computer started up and auto-adjusted its settings without me doing anything. IT literally takes 20 secs to load Win7 ultimate as compare to before, it would be like 45 seconds.
Idles temperature for cpu is like 32 degree. (i dunno if its bad or not, this figure came from the bios menu)
NOw I will sit and wait for NCIX boxing day sale for a nice video card.
thx for all the advise in this thread
p.s should i sell FX-62 for cheap ($50) or build a HTPC with it down the road
