I plan on OC'ing both the CPU and GPU's as well, it looks like this CPU/GPU combo will do that nicely. I believe the liquid cooling will help with OC'ing as well, but would I need a better PSU with OC'ing both? I am going with that particular case since it looks like it has very good airflow for the heat.
From my research going dual GPU's will help with framerate and such vs going with one high end GPU. Is that true?
A 700W PSU is enough for overclocking both your CPU and GPU. 850W is overkill unless you're planning on slapping on a second 460 in the future.
That case does not have good airflow. Not only does it not have good airflow, it doesn't have cable management. Cable management and good airflow are essential to good overclocking. Lower your PSU to 700W and use the saved cash to upgrade your case to this
. It's the case I'm using, and it is absolutely excellent for its price. I give it a full 10/10. Get a few more fans and install them on it. It supports up to 8 fans (7 if you get the translucent side window, which I'm using). It should already come with 3 fans (mine came with the front, rear, and one top), so fill in the rest as you see fit.
About the dual GPU vs one high end GPU. It depends which models. Two GTX 460s, for example, outperforms a single GTX 480. But if you're using two old GPUs, they won't be able to compare to the 480. Edited, Aug 23rd 2010 11:41am by Threx
