Upgrading Power Supply and Graphics Card on an Old Computer

Hi Guys,

I am considering upgrading my old ASUS computer to better handle 1080p gaming, however i'm uncertain about a few things.

Current Specs:
Model Number: ASUS CM6870 https://www.asus.com/us/Tower-PCs/CM6870/
Processor: Intel Core i7 3770 3.4 ghz
Power Supply: AC Bel HBA008-ZA1GT 350 W
RAM: 16 GB DDR3 (4x4GB RAM)
Graphics Card: GT 640

I want to upgrade my Power Supply so that the computer can run a GT 1070 Graphics Card

Will this be possible given my current Specs? Will there be any bottleneck issues or problems with installation/fitting?

Additionally, will i notice a significant improvement in gaming or is it a lot better to just build a new PC from scratch / buy a new prebuilt system?

Any help is appreciated. I am very new to PC building so if there is any additional info needed please let me know.

Cheers!

    You would be fine to whack in a GTX 1080 as your CPU is still a worthy chip, especially for 1080P gaming. I am still using my 1st gen i7 running @ stock 3.07Ghz along side a GTX970 GPU, and the CPU just about squeezes the card to its limit, but that is both CPU and GPU running at max - which i feel is perfect for me at the moment still. Getting Full 1080p @ around 70+ FPS on BeamNG.drive - which is very CPU intensive.

    For the PSU, it really is up to you, but i would go for something decent, as you are adding a new GPU, and you want it to give enough power, and protect all your components. Something from Seasonic, or the Corsair RM***x series are great units (budget depending!) Around the 550w mark would be plenty, and afford a bit of headroom too.

    Another thing i would suggest is to invest in an SSD (Samsung EVO range are great) This will speed up windows loading times and game loads hugely, and will in turn, alone, will make your PC feel much faster. The SSD migration / mirroring process is very straight forward too!

    Hope this helps.
