I was thinking my power supply may be to low? I am using a 650 wat.
If it is from a quality manufacturer, it should be fine, but since the MAJORITY of available power supplies on the market are at best, only average, and far too often are very poor quality, the BRAND is often more important than the advertised wattage.
When it comes to SLI and Cross-Fire, it's sometimes a case of "it depends" about the first and second PCIe video slots. Very often, the second slot had only half of the bandwidth offered by the primary, first video slot. It potentially amounts to quite a difference for a high end card.
Lastly, AMD got caught in the dual failures of the two Fabs they use. Both Global and TMSC were originally promising to have 32 nm plants running last fall, then neither was able to do so. Everything AMD had ready for current upgrades had all been designed for the thinner wafers, and the GPUs were first to be disrupted, as they were due out with the startup of the TMSC new Fab, in October.
Two new cards, and two year-old ones, compared:

The 6800s did get some new functionality that the 5700s hadn't had the year before, along with bandwidth improvement, from 128 bits to 256 bits, and AMD initially announced that the two 5700s would remain in production without changing anything.
Pressured by OEMs, for whom they had reflashed the BIOSes on chips sold to Dell and HP for certain, they are now selling 5750s and 5770s that have been renamed, only, as "6750" and "6770" cards.
