it's nonsense then ... how can be adeon 7970 saphire with 1000mhz stock clock faster then MSI R7970 Lightning 3GB @ 1265/1505MHz ;/
When we move to 5760x1080 things do change a little. The 7970 is able to pull ahead when running at its maximum clock and the GTX 680 then competes with the reference 7970, the NVIDIA card just pulling ahead.
it's to big resolution i know ... but it had to let me think about one thing ... that 7970 CF will be better choice then 2 gb 680 for future ... but there will be 4gb versiosn of gtx 680 to .... problem is .. they will cost around 800$ ...... lame ....
