I had questions about the speed as well. Seems low, evga already above it. 1020/xxxx sounds better. If this 1020 was the boost speed it is a failed product. I don't believe there is a 780 or 780ti on the market that won't hit 1020 BOOST out of the box already (eh, 1100 would be more true-pretty sure every review has them hitting that or more). On an OC card I expect 1020/1150 from 780ti.

1120/1173 for OC on ref design. You should easily hit 1025/1125 roughly with NON-REF OOBE (and more OC on top-I just expect this out of the box). It's clear NV was shooting very low.
"It's been a while since I've seen a GPU do almost 30% OC on launch day."
I'm surprise 780ti wasn't in the readers choice awards list. The 290x is but you can't even get it for $600, and it's hot, noisy, throttles all day etc. How can a card you have to mod (or drive noise up until you can't stand it) from day one, have patches on launch etc win anything? Whatever.
