aionwannabe:
unless you plan on waiting till the 670 and 660s are announced that's a pretty decent build, I assume you've read about Ivy-bridge's temperature issues?
Nah, waited long enough. I drooled over the recently-announced GTX690 but that could conceivably come in around $1500 by the time it hits here. That would definitely need a Lotto win!
I've been waiting for Ivy Bridge and expected to see heat issues. It is pretty much a no-brainer that increased thermal density on a smaller process node would result in higher temperatures for the same clock speed as Sandy Bridge. It's going to be interesting to see what temperatures people start reporting now that tests can be run on the release models and in real-world situations.
However, even so, I am happy to OC just to 4.5GHz and the reports to date indicate that this will be fine. Hitting 5GHz is great on a system that is primarily a gaming rig but my PC is around 80% graphics & development work (plus all the other myriad tasks one uses a PC for) and 20% gaming (if that). 4.5GHz is a bit blerh for gaming but a sweet spot for all the rest. Early reports indicate it's stable and doesn't run hot.
Did you see this?
Intel's 22-nm process allows Ivy Bridge to consume much less power than its predecessor when running at the same speed. The 3D transistors purportedly offer better performance at low voltages, which is great for mobile applications but perhaps not ideal for overclocked desktop rigs. That said, I'm reasonably impressed with how well Ivy overclocks. The Core i7-3770K was stable at 4.4-4.5GHz without so much as an extra millivolt applied to the CPU. Those speeds only increased system power consumption by a modest amount, so there's no need to invest in an aggressive cooling solution. With our single-fan Frio config, CPU temperatures were in the 50-60°C range under load.
