Real-world Boost out of the box is 1328 MHz. Considering the [H] review where they overclocked a reference card to Boost at 1410 MHz and observed gains were between 15-20%, I'd say the SC version is around 10% faster than reference out of the box.So how much faster is this compared to the stock Titan X? 5% I assume.
Learned my lesson on how quickly I got hammered on the Titan Black. Never again on the Titan line.
The whole Titan line is an absolute rip. I got burned on buying 2 original Titans only to have the 780Ti come out and smoke it. There is absolutely no need for that much VRAM at 1440p with G-Sync, and paying that much premium for a stock design on stock cooler is just silly.
Resale value on the Titan Black is still pretty good though? I see listings on eBay going for $700 or so... not sure how you got burned when you could sell it and get the faster 980 or step up to Titan X - an extra $300
If you bought it just before the 980 released, yeah that's tough, but all indications were pointing to Maxwell coming out soon. I wouldn't have bought the Black for that reason, original Titan was a far better buy considering the state of the market when it came out.
