I'd just OC in the BIOS. It's easy: just set the multiplier. You won't need more than maybe 4.2ghz (and you'd be fine with 4.0) with one 570, and the 2600K will hit that easily without any tricky voltage or BCLK tweaks.
Those programs or Speedfan or Hardware Monitor. Anything should work.
What convinced you to drop an extra $50 on VRAM? Are you on more than one monitor?
Ok - I didn't get to play with much last night - I let myself get side-tracked on a warning message from Windows about Graphics and memory and thrashing...it wanted to go back to Windows Basic display or something - ridiculous on this box I would think. Ended up reinstalling the NVidia drivers clean from scratch - played BF3 until I had to go to bed. No warning, so I hope I have that licked.
Two Monitors: definitely in the works - just doing homwork. I only have the one 27" 1ms Samsung LCD right now, but shopping in the 23" neighborhood for a pair of 2ms. Wrestling with brand, price LCD vs LED, and reviews. I like Samsung, but Costco lately only has the smaller (like 23") with no DVI inputs! (crazy!) Also, there seem to be a lot of options even in the same brand, same size within $10-$20 of each other. So I can't help but wonder what the difference is (and which one is better?!)
So, why the extra $50 - easier to get now, and in case I wanted to go crazy and SLI, the 570 was cheaper than the 580 so I splurged on the memory in the mean time. Also, that hopefully will make the additional card optional having the extra VRAM.
I do hope to tweak and monitor(temperatures, performance, etc.) some this weekend... but little experience in tools to do this. (Thus the thread)
