ok i guess you are right, i've been doing alot of comparisons with other similar systems, does this look right? other users are getting like 1k to 2k higher after that they all use 2 gtx 970's. I mean don't get me wrong i like the upgrade i did but it doesnt seem like a huge bump from an i7 920 at 4.0. although games run a "bit" smoother on places where it used to hitch..
I'm considering on getting another gtx 970 i don't know if that would be wise...
I see you have an EVGA motherboard. Just a heads up if you do go SLI with GTX970 or 9 series card. The low gap memory setting will have to be increased in BIOS, or you may have booting/restart blue screen problems.
Also I see used GTX980Ti cards in the 330-350$ range and prices are dropping. Might be worth it for you to sell your 970 and get a 980Ti.
Food for thought.
