Generally, CPU overclocking wise, the results are similar between the 3 chipsets and it is the board's features like VRMs, BIOS that determines max overclocking potential.
So, a 970 would be fine for someone like me, who never used Xfire? All my boards the past five years have had Xfire support but I've actually never even tried it. The one and only time I've tried SLI was with two 7600GT's on an nForce 4 chipset and wasn't impressed.
Reason why I ask is because I'm thinking of replacing my motherboard and CPU with something newer, without spending loads. Also my offspring's PC is really frustrating me as her new motherboard (new Gigabyte G41) has problems with USB drives and crashes from time to time.
