(thank-you very much for your research, suggestions and efforts to help with this!)
No, it isn't ideal to use Z68 but there is absolutely no time for me to get a new MB and setup windows and 20-some games and many benchmark tools; it would not arrive until late Tuesday afternoon if everything goes perfectly - even by paying for overnight shipping!
However, i can use my i3-2105 right now and do a brand new OS install tonight on my ASRock Z68 Extreme Gen3 MB today. It will be ready for Monday and i will have tested the new OS install for stability.
i will probably have a most unique evaluation and it will be quite valuable to those who may be doing the very same thing. At the end of the month, we can see what an EVGA Series 7 motherboard brings over my ASRock Z68.
Best of all, i will be $200 less poor; plus i will sell my Z68 MB after i get my flagship platform set up while it is still worth about $100 used. And i will be able to sell my i7-920 platform and buy more AMD video cards, if necessary. What i will be selling, i bought out of my own pocket. So we can keep relevant benching going on at ABT
