Now I am just looking to build a new system. I am looking at either and i7 or an AMD ryzen. I have always loved EVGA products.
What I have to carry over is:
Corsair HX1200i psu
2 eVGA 1080sc
12 gb ddr3
Antec 1200 case.

Probably looking to buy (spend $500-$900):
CPU
MB
Likely RAM

Currently have x58 Classified System

My advice, take some time and compare detailed specs and features between motherboard mfg. If you see a mfg listing generic specs, they probably trying to hide something from you. See what hardware people are using or recommending on other forums/websites.

Intel CPU, if you want the best gaming performance
At least 16GB of DDR4 RAM  (2666-3200mhz)
Hard to go wrong with ASRock or ASUS motherboards
I would carry over the Sound Blaster Z
 
Watch out when purchasing the new hardware. If you purchase it on Amazon, make sure it's sold and shipped by Amazon.com. If you buy it from Newegg, make sure it's sold and shipped by Newegg. I recommend buying from Amazon, they take better care of customers. No matter the time of year, Amazon never makes you wait 30-60mins to chat with a customer service rep, like Newegg is known for.
 
X58 was a beast. I upgraded from X58 i7-950 to Z270 i7-7700k in early 2017. I could notice a difference in performance gaming and encoding movies.

Looking at:
Asus Rog Strix H370F gaming MB

i7 8700k cpu

G.Skill 16GB (2 x 8GB) Ripjaws V Series DDR4 PC4-25600 3200MHz Desktop Memory

What cpu cooler that fits Antec 1200?

Already have:
Antec 1200
Corsair Hx1200i psu
2 evga 1080sc in Sli

Any opinions and input greatly appreciated

Ok looking at these two builds now:
 
Crazy too many choices. I mostly do gaming and some Photoshot and editing but not regularly. I know 8700k is better for gaming than the 2700x, however, is it in the end going to make the difference of actually playing the game or not? I am looking at VR in future. I have been a diehard Intel fan for years now, however, I don't have a problem moving to AMD if it saves some money. Maybe a couple hundred.

I went with amd setup and got 32gb ram and a Samsung 500gb m2 ssd.

No I didnt get the 150i. Do you think that would be an overkill for the Ryzen?

LMAO, that budget got blown straight to hell in under four posts. I feel your pain. I'd save up and plan a build around DDR5 ram, PCIe 5.0, and when those come out next year-ish, check the new CPU/chipset meta. Remember to plan around your use. Not optimizing your system for your use is a sure way to waste money.
