i think the issue is not with the added .025v you may add to your cpu core v, of course you wouldnt need an extra 100watts of power to handle that, but the strain the overall added speed has on your peripherals. for eample, i have a 300w pwr supply and could run my system perfectly with an 850 tbird at 200 fsb. i bought a 1.33 266fsb tbird and i have to downclock the fsb to 248 for it to run at 1.33ghz. am i making any sense?
...and i would have gotten away with it, if it weren't for you meddling kids...
