[SOLVED] Will PSU hold? Will CPU Bottleneck?

[olavthomas94]

thinking of replacing my 1070 with a 2070 or 2080/2080ti
(ASUS GeForce RTX 2070 ROG STRIX OC, ASUS GeForce RTX 2080 ROG Strix OC, ASUS GeForce RTX 2080 Ti ROG Strix OC)
will my PSU hold?
will my I7 bottleneck?
do you see any other problems?

Spec:
Intel Core i7-7700K CPU @ 4.20GHz
16GB DDR4 RAM
Motherboard: ASUS STRIX Z270E GAMING (LGA1151)
GPU: EVGA GeForce GTX 1070
1TB SSD Samsung 850 EVO
WD Red 4TB 3.5" NAS HDD
PSU 650W (Corsair RM650x 650W PSU)

Want to run a 27" 1440p 144hz g sync preferably on ultra in games
and a
24" 1080p 144+hz g sync side screen for info/stream or even side view..

Any help is good

I would grab the 2070 for the 7700k and PSU is PLENTY OF RELIABLE POWER.

TBH I am tilting towards the 2080TI... want everything to run as smooth as possible and I love the high fps high-quality gaming

The 7700K will bottleneck the 2080ti some , probably between 15-20%.

Fps is all cpu. Gpu just has to he strong enough to get to that fps with the user set details at the chosen resolution. Getting a stronger gpu will not increase fps if the cpu is maxed out. So if the game code is so badly optimized (think Assassins Creed series) that the cpu can only dish out 60fps at ultra, and lowering the settings to high doesn't change that number, getting a 2080ti won't give you 144fps.

A 2080 can handle just about anything at 1440p/144Hz, there's only a handful of games graphically challenging enough to require the Ti. A 2070 can handle a good 90% of games.

With that 7700k, you stand a better chance of cpu capping fps than a 2080 not being strong enough.

So a 2080 is the way to go and save for CPU upgrade?
maybe use the difference to save for a new CPU and add some ram?

There is no cpu upgrade without motherboard change, you've got the best cpu possible for that generation.

If anything, I'd be looking into really good cpu cooling and get some speed out of that cpu, 4.8GHz or better, the faster the cpu, the higher the fps ceiling. Paired with a 2080 1440p@144Hz shouldn't be an issue except in a few games, and those can stump any cpu.

You don't have a need for more ram, even running 4k ultra most he's are hard pressed to use more than 10-12Gb system ram total. At 1080p I don't own any game that exceeds 5.6Gb of system ram usage.
