I would say the basic idea is to NOT let your VRM (or any component in your card) reach 100 C. 90 is probably higher than you want as well (not that it will do damage, but it's probably closer than you'd like). From my perspective, a healthy, stable OC on my card I don't want ever reaching past the mid 80s, if that. But don't be too discouraged, it might very well be that you simply need to fiddle with your fan profile to keep the temps down. I have a custom fan profile in afterburner, which ramps up to 37 until I'm in the 70s, and then slowly climbs to about 45 in the low 80s. I've never seen it reach the 80s with that profile, but I suppose every card is different.

To be fair I'm not sure how much ASIC quality is relevant to things like that setting in afterburner. Maybe someone else can weigh in, but I've always just put it on the highest setting, and forgotten it.

As for the power control, I think conventional wisdom says that if you're going to overclock at all, you should up power control to 20%. Again though, if you're concerned with the temps on your VRM, it would probably be a good idea to be careful about how much you overclock, or how high you have your fan settings.

VRMs should be able to take up to 105c-110c iirc, so you're in the danger zone tbh. 80c-90c just sounds a little bit too high even for an OC'd card. You should try and do whatever you can do lower the temps, so even things like improving airflow inside your case should help.

ASIC quality is supposed to tell you the quality of the GPU chip and if it can OC well. However, it's not 100% accurate and doesn't necessarily guarantee you this, since I've had a card that was in the 80% mark also but couldn't do 1150mhz on the core. In your case, just leave MSI Afterburner to do that setting if it is defaulting to that voltage upon rebooting your PC (remember that AB tells you that it needs to reboot to check the settings and voltages).

That should be fine since AMD even have such a feature in their Overdrive in CCC, and they know their limits and boundaries for the most part. I would set it +20% since you've OC'd your card in order to provide it extra power headroom.

Hey guys, been using nothing but Nvidia cards , so thought I'd try an AMD, I see a lot of unfamiliar Companies (Again used to Nvidia) and was wondering if VisionTek had a good reputation, I noticed they do have a Limited Lifetime warranty on their 7970's, who is the most reputable Company to buy a 7970 from?

Asus, MSI, Sapphire is usually who I buy from. Went XFX this time around though.

No worries dude. I hope you get your card where you want it to be. These cards are really great, but sometimes you have to fiddle with them to get them just where you want. The end result, though, is totally worth it.

What he said is basically right. Asus, MSI, Sapphire. Sapphire does the most sales, iirc. But MSI's warranty is tracked by serial number so even if you lose the receipt, you can still get service, and it even covers overclocking, as long as you don't damage the card WHILE taking off/putting on the heat sink. If you were going for a non-reference design, Gigabyte's card is well thought of from what I can tell, in addition to the other brands previously mentioned. Also, in that same vein, if you were going with a non-reference design, the Asus non-reference cooler (on the 7950) had some SERIOUS quality control issues where the heat sink wasn't properly screwed down, so you might avoid that particular card if you were a little concerned.

Just some clarification this is thier mid-level 256 bit card. What's confusing is its got the 680 name like the 580 yet is not its counter part. It's like thier 560Ti equivalent.

They will have a 320 bit GPU for thier 570 eqiuvelent and then even one higher, flagship card will be a 384 bit and naming has not been determined on these yet.
