All solid. OP check my sig rig. I love my Gigabyte UD3 mobo -- it's solid as a ******* rock.
I've been running my 1100T for 2 years @ 1.500vcore. The UD3 mobo easily lets me push my NB to 3000mhz and 1.350v. It's interesting, actually. As you can see I'm running 2 560s in SLI and they generate quite a lot of heat. Interestingly, the NB heatsink is directly above the top (normal, single) GFX card slot. While obviously not directly attacked it or anything, it seems to absorb large amounts of heat that comes of the exposed top of the GFX card near the heatsink.
For example when gaming the heatsink becomes extremely hot, and if I run a SINGLE card in the BOTTOM slot, it the NB heatsink will be much cooler while GFX card will either run hotter of ramp its fans up more.
TLDR: Lastly....As great as the UD3 mobo isI'd CONSIDER (since you have the $400 limit) looking at a 990fxa-UD5 instead. It's basically the same mobo with even BETTER heatinks and even higher quality transistors.
This may end up being a benefit to you with an 8350 vs. the lower power draw of my 1100T. Then again, I'm also running 2 560s as well.
And on that note -- I'd STRONGLY suggest a 750-850w power supply. This way you can just buy a duplicate of your graphics card for a fraction of the price it is now and basically double your performance in many/most games.Edited by LesPaulLover - 8/6/13 at 4:15pm
