For those who can o/c their 4850 to over 700 Mhz, what method to you use to bump your voltage up? Most 4850 can't go over 700 Mhz without bumping the core voltage.
If I'm considering oc/ing my 4850, but I will not do it until I can be pretty sure that I can get it enough juice to go to at least 700 Mhz (on a stock cooler). Anything less than 700 Mhz is not significant enough for me to mess around with. Eg, a 50 Mhz bump is less than a 10% in core clock increase and is probably too insignificant in gaming.
I have an intel P35 chipset, so I can't do SLI, and this chipset is too slow to CF.
But hmm a combo of a 9800GTX+ plus a cheap (ebay) 8800GT/9600GT for Physx sound intriguing to me. hmm....
