If it's supposed to overvolt that far, then it could be slightly defective. =P Really, the way I see it, all CPUs have different amounts they can be overvolted. The companies are supposed to give the CPUs a little headroom, but if they don't, then I'm not sure you can complain, since they do work fine at stock voltage.

I specifically said I had NO problems at that voltage with a G92 8800gts. My CPU could take up to 1.55 volts without a problem before I got GTX260.

edit: I run my system 24/7 BTW so any little things like this I notice right away.

ok so to sum it up... Id have to agree that theres no chance in hell u will want any high end vidcard like a gtx 250 or higher or an ATI 4850 or higher coupled with a 300w generic psu... which would not have more than 22A on the 12v rail.... u want at least 28A to run a dual core and 1 of these cards... and this does not include overclocking...

So ur choices Op are a little tough...

1) get a new power supply and vidcard... and overclock ur cpu if possible to as high as u can
2) get a whole new system ( id get it from Cyberpowerpc.com, since u dont like to build em urself, at least there u can customize every component u want in it)

Yeah, the arguing in this thread is embarrassing. If he wants to keep his current PSU, then get nothing higher than the Radeon 4770 - but that may still be taking a risk. A safer option is the GeForce 9600GT. It uses almost the same power as the Radeon 4670*, and more often than not is the faster card, making it the better choice between those two.

*Same watts, but it does require an extra power connector

So get Radeon 4770 or a GeForce 9600GT, the former being faster but requiring more power. Or get a new PSU and a Radeon 4870 512MB.
