New to stuff like OC, sorry.

1) Hey, just about to build a new rig. Plan to do some minor ocing, and just wondering, what is the limit for CPU temp, to be really safe? Like, 70? 80?

2) If I use Catalyst to up my GC a bit, do I need aftermarket coolers? I'm using 5850, any recommended coolers for that?

3) Also, I'm using i5 750 with Xigmatek Balder, plan to OC till between 3.2 and 3.5, temps are going to be manageable, right?

4) Does lowering the vCore also lowers the power consumption and temp?

5) The temps for the other parts eg, RAM, HDD etc, they are usually negligible, right? As in, they aren't as high as what the GC and CPU will go, so no need to be bothered?

6) Finally, if we keep the CPU temp really low, can we extend the lifespan of the CPU, regardless of OC?


Thanks. Dunno if this is the right section for these questions....

Ok, thanks. I've checked some reviews, the stock 5850 can go to 80 under load, so a bit worried about oc.

Is it possible to get >3ghz with vcore lower than default? My priority is getting significant improvement in real life performance, then lowering temp/power/noise.
