the difference is not negligible. bruennis who moved from the gtx 680 lightning (1372 mhz) to asus hd 7970 matrix(1320 Mhz) says the difference is 10 - 15% in BF3. Games like metro 2033, crysis warhead are landslides ( > 25%) for hd 7970. here is a GTX 680 lightning oc vs hd 7970 matrix oc review

Tahiti while hotter won't lose their OC to thermal throttling until you get into VRM temperature danger zone.

Seeing as the Tahiti cores really don't like temperatures above 75C when going for the maximum OC, I'm not sure this is a valid point. Tahitis don't throttle, true, they just become unstable.

Thread Starter 
I have an Big Tower HAF x with original fans, that enough for keeping my 7870 under 50 when i play Metro 2033 on highest grapfs. (I just have stutters at some random walls lol).

The thing is that the game random crashes, but that's a malfunction.

My experience with AMD is that they are very hard to "kill" even in high heats.

Cleaned. "Name-calling" contributes nothing to discussion. Please refrain from flame baiting.

I have a accelero extreme on my 7970 and it never goes over 60 degrees on my big oc. Temps mean everything to get good oc on these cards. idle never goes over 30 and the fans at 100% are almost impossible to hear
