I had problems loading the drivers, so I backed up my essential info and reformatted the hard drive. Then loaded the disc with a fresh hard drive and updated the drivers online. The 6670 was working properly. The 6770 on my new computer only gets a 320 on this utility as well. Not sure why the GT430 scored so high, when it's supposed to be so much slower than the 6670 or 6770. Maybe something to do with the Motherboard or AMD processor configuration, better drivers?
And, No, I've never heard of a "driver cleaner". But my hard drive was clean.
Run 3dMark Vantage, see what you get. Some cards run better in some operations than others. That stability test does not really test out the capability of the cards.
Think of it like the Mario Cart cars. You can have a car that is fast in acceleration, it will beat a slower car in a straight line, but once you hit curves it will fall behind to a car with better cornering and balance. What you need to do is run a test that tests many functions of the card not just a few. I have run that stability test before, and it's a pretty simple thing, not really made to benchmark cards, just heat them up to see if they crash.
Yes, the same monitor/resolutions... that's what I was thinking too, about the utility. Sadly, all those cards are gone along with my old computer that I sold. I pulled the 6670, then sold it, bought the gt430 (got it for $42 after rebate) as a replacement for the person who bought my computer. 5450 is long gone, gt520 was put into my brother's computer...
My uses are mainly my personal photography/hd video rendering-editing, I've started playing SAS Zombie Assault 3 online... do I need (or want) to upgrade or is the 5770/6770 ideal for my purposes? I was thinking about upgrading to a gtx550ti or hd6850... Also thinking about "downgrading" to a card that is mainly suited better for 1080p rendering (I may be wrong but the Nvidia cards are better at this).
I've heard of PhysX, but I don't think I understand what it is...
