6870 is better but don't believe on XFX brands they have major issue that is heating and also there is not too much difference between them now 6850 is way to go MSI run cools and perform very closer to 6870.
Lol ok then, well I wasnt to sure.
because the 6850 is 860mhz and 4400 mhz with 906 cores
but the 6870 is 900mhz and 4200mhz with 1120 cores
so I was thinking will the 6870 with more cores not be the better option?
there also a VFX 6870 for the same price if that makes a difference?
