Jakez2012 :
I can now say I heavily agree with you, I hadn't realized how much better a good oc card performs than a lesser one. This goes with why the asus might not be the best and I now realize that. To compare results I suggests you watch Linus Tech Tips video: https: //www.youtube.com/watch?v=Eqz4tDM6Wl8
This shows results of a better oc 780ti to a more average 970 compared to the results you showed.This just show how much a good oc can affect performance. Thank you for warning of the issues I might face before I rushed the purchase.
I disagree with Linus a lot but one thing I have to compliment him on is the "apples and apples" comparisons ..... he's one of the few sites who published data detailing why the 290x was not in fact faster than the 780. The 290x was very aggressively OC's in the box leaving very little headroom for overclocking. When both were overclocked "bawlz to the wall", the 780 proved to be the faster card.
Keep in mind that when we see web sites doing OCs they tend to be a bit conservative....they don't want users copying the settings and then having problems I guess.... when i have done it myself, I have always been "luckier' than 95% of the reviews. I never did hit the 30% OC that some sites got on the 560 Ti.
Here they got the MSI to 1567 ... 100+ over where Linus got the Strix..... 3 of the 4 detailed reviews I have read "cover to cover" broke 1500....

MSI has done a fine job of late .... thru the 5xx and 6xx series I used Asus exclusively. With the 7xx series early on I was using Asus for the 780s and MSI for the 760 / 770s .... then MSI retooled the 780 and I switched to MSI for the air cooled builds and used MSI / Asus for water.
Better than average performance doesn't arise out of a vacuum. If ya read the Bit-ech 970 roundup article, the reasons between the Asus and MSI card's performance becomes readily apparent. Both the component selection and how things are cooled vary significantly.

The 780 To overclocked fits niocely between the 970 and 980.... though closer tot he 870 than the 980
