Compared to a GTX 680 OC Signature I previously owned (was able to get the boost clock to about 1175 core/ 6500 mem), would the OC done on the Lighting provide a noticeable improvement in gaming and benchmarks?
Depends what it hits. New ones aren't all hitting 1400mhz+ like the new ones when they were first released did and after they got voltage control. I don't think you'll see many doing ~1350mhz on the stock voltage anymore, due to the less-stringent binning process now in place. But yes on games where you really need the power (there was a 99% load when you were at 1175mhz core), then you'll see a small increase, but not enough to make a previously-30fps-game playable. Every little bit helps though I suppose. And yes the flashing is easy as can be. Post any question here that may arise
So pretty much everyone has more experience with this than me, since I've had mine on the LN2 BIOS from day 1. I finally decided to check out the non-LN2. You don't have to reinstall drivers every time you switch from one to the other do you? I switched over for the first time, and even though the resolution is fine and the cards are recognized, the "Installing Device something-something" popped up when I rebooted and it was installing a Generic VGA driver. And the generic VGA driver installation failed. This mean I have to reinstall the drivers for the cards to be fully recognized and taking instructions from the drivers? Their recognized in Device Manager and by Afterburner.
