I've had my msi twin frozr III 6950's forever, so i sold them to my friend and used the funds to start a cf setup with 7970's. I only bought one card to start so that's all i'm using, and it seems a bit of a sidegrade, although i tend to notice better performance in the games i play which is nice. I just got a couple questions. Overclocking? What max voltage and temp is safe. I'm currently at 1.20 1125core/1550mem. Temps don't go over 70 during 3dmark11, let alone any gaming. What is the best program to overclock with this brand of card? I've never had a diamond card, so this is a first. MSI afterburner was my choice for my old cards and it seems to be working fine now? Stick with it or is there a better option? Bios switch? Does it work just like it did on my 6950's.. and is there a custom bios out there i may be looking to switch too? Sorry to just come out with some questions right of the bat, admittedly i haven't done much research, it's all impulse and my searches are not turning up anything concrete?
