I drop down clock to see is it bottleneck visible on i7-3770K on GPU Score, I couldn't imagine more than 400-500 points less on P score, I was shocked... And yes hit about 100 points and on GPU too...But we can't call that bottleneck but we can say GTX780Ti work better 1-2% on higher speed even with Ivy Bridge 3770K...Before that I thought 2500K stock is enough.
Except that both results are stock clock graphic card 1072/1750MHz... I can push CPU to the 4.8-4.9GHz, 4.8GHz is last what I have stable because temps, confirmed with 12h Prime95 AVX on overclock,net Suicide Club, mine name is there, everything with H100 on summer, with more than 90% memory on 1300V or 1200V 4.5GHz...CPU Clock is not problem...but I though GPU result will be absolutely same, but it's not, difference is really small but 1000MHz OC influence good and on GPU... Off course I never keep CPU on last clock, on 4.5GHz I have 300MHz free...
I don't know what to say except next time you must prepare better.
They will launch such cards for every architecture for best model, as GTX580 Classified ULTRA - GTX780Ti KP Classified... Than everybody who wish can prepare money, save little more and must react fast to find sample for self... Like you see many people wish this cards, some of them buy few, they are not overclockers all of them. 1:5 is biggest chance to find something nice in such cards.
Or you can save money and play with reference cards, what you like, I wait models as this. Soon I will overclocked card on your clocks than we can compare results. If you ask me everything is like they promise, 15.000 in 3DMark 11 on 1200MHz with 4960X overclocked to 4500MHz, I have more than that with 3770K on 4500MHz and you see difference with CPU, I could expect near 16.000 with 4960X 4500MHz or who knows, but give us what they promise. Even people who can't OC card well maybe their models are exactly best under dry ice...They are not binned for Air, but I'm glad because work excellent and on air.
