Today I picked up my second GTX 680 Top card and I was wondering if these benchmark scores are normal

I overclocked my i7 3820 @ 5.035ghz with boost enabled

Both 680's are running at
+65 on the core clock
+420 on the memory clock
+159% power limit
+100mav

I ran 3d vantage on entry test and I noticed one card boosted at 1305mhz and the second card boosted at 1280/1295mhz my final score was 75556 something along that number is this normal?

Benchmark some games, not synthetic benchmarks. Vantage is rather CPU bound.
It's normal that two cards might boost to different levels.

Using a i7 980 @ 4.2 and a GTX 690 I got around 20k in the graphics in 3Dmark. I'd imagine you should get quite a bit more. (I think that was in the basic mode that was unlocked was it only 1280x1024 or something in the free 3Dmark mode) Just to give you a starting point that you should easily beat with that setup. Haven't tried 3D vantage.

+65 offset doesn't really mean much because of the random boost speed Kepler gives you. I had a TOP which boosted to 1280. Your speeds might just be because Kepler has random boost speeds, won't boost to max speed unless it needs to, or you're over a temperature threshold. Try playing some games, because Vantage is old and isn't going to tell you much.

Perfectly normal for Kepler cards to have different boost. I have 2x ASUS GTX 670 SLI DC II 'Non TOP'. My upper card boosts to 1124MHz at max load, while my lower one boosts to 1084MHz on max load. Upper card is also a much better overclocker. Can easily do over 1300MHz boost. While the lower one is a bad overclocker. Can barely be stable at 1124MHz if my memory serves me right.

I have two TOPs. At "stock" clocks they boost to different values. However, I currently have them set to boost to 1300 MHz. I achieved this by using MSI Afterburner and tweaking each card individually.



If you want to see if your cards are stable run a few loops of the Crysis benchmark, 3DMark 11, Metro 2033 benchmark, etc. I also like to use Furmark.
