[SOLVED] Graphics Cards and Bottlenecking Cont. Ways to Adjust for Bottlenecking

So as a continuation of a separate thread I made earlier regarding new gpu choices, I wanted to know the best ways to adjust for cpu/gpu bottlenecking (where the cpu can't work as fast as the better, upgraded gpu). I want to know this because the build I am upgrading will eventually get more upgrades in the future that will balance out the performance gap between the cpu and gpu. But for now, I am planning on buying just a newer gpu (as well as more RAM, +8GB) as that is what I have mula for.

For those that did not see my earlier thread, here are my pc's specs:

Motherboard
ASUS P8Z77-V LX LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard

https://www.amazon.com/ASUS-P8Z77-V-LX-Intel-Motherboard/dp/B007MKGF82

CPU
Intel Core i5-2500k Quadcore processor

https://www.amazon.com/INTEL-Core-i5-2500K-Processor-BX80623i52500K/dp/B004FA8NX2/ref=sr_1_fkmrnull_3?hvadid=177308009445&hvdev=c&hvlocphy=9052045&hvnetw=g&hvpos=1t1&hvqmt=e&hvrand=5922163530290810061&hvtargid=aud-647006051489:kwd-29913063083&keywords=intel+core+i5-2500k+processor&qid=1553465110&s=gateway&sr=8-3-fkmrnull

Graphics Card
MSI Geforce GTX 650 ti

https://www.amazon.com/MSI-GeForce-Graphics-N650Ti-1GD5-OC/dp/B009WIW87E

Power Supply Unit (PSU)
Corsair CX750M (750 Watts)

RAM
CORSAIR Vengeance 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model CMZ8GX3M2A1600C9B

PC Case (Tower)
NZXT Guardian 921RB 921RB-001-BL Blue LED SECC Steel / ABS Plastic ATX Mid Tower Computer Case

https://www.newegg.com/Product/Product.aspx?Item=N82E16811146070

I have basically narrowed my choices for the graphics card down to either the Nvidia Geforce GTX 1660 ti or the AMD Radeon RX 570, both of which I acknowledge would cause cpu/gpu bottlenecking but would provide me with the dramatic visuals boost I quite desire in The Witcher 3. The 570 would be more cost effective, but I am still considering the GTX due to the fact that, as stated earlier, I will eventually upgrade the other components of my pc later on until the entire machine practically becomes a brand new pc. Also I am not familiar with AMD hardware and so would not be sure how to properly switch from my current 650 ti to the Radeon in terms of software and driver installation/uninstallation. What do you think I should do? Do you have any other smart choices for gpus?

Thanks

For switching there is nothing so time consuming.
Just unistall the old drivers ,put the new card inside and install it's drivers.

Now answer for your bottleneck.
It will be a bottleneck depending on the game, for example Battlefield really enjoy more threads and games that don't will benefit anyway from higher IPC and clock, but you will see an astronomical boost on performance anyway as the GTX 1660 Ti is way way faster than your GTX 650ti(consider that even a GTX 750 is faster) and your CPU still a decent one.

And to make it minimal you can easily overclock your cpu to 4.3Ghz to 4.4Ghz with proper cooling and it will show minimal bottleneck.

As i said before both gtx 1660ti and 570 are decent but 1660ti is more powerfull and will perform better with your cpu when oc to 4.3 Ghz as compared to 570.
My friend has a gtx 1070 with i5 2500k(gtx 1660ti is equivalent to 1070) and he has oc his cpu to 4.4Ghz and there is minimal bottleneck and only in some games there is a loss of some fps rest all works good.

Thanks for the info! Regarding overclocking, what would be considered proper cooling? My pc is placed under a desk in a special closed compartment for it, which prevents a bit of dust buildup, but not sure how well it does temp wise (nothing has been damaged). Do you mean liquid cooling might be needed? Otherwise right now I have the standard 2-3 fans mounted off the rear of the tower, one side, and the inside, along with the psu's own fan. If that is not enough cooling to you, what do you suggest I do to safely overclock my cpu?

I have seen many people pushing the i5 2500k to higher than 4.5Ghz which requires a liquid cooling system.
But in your case to overclock to 4.4Ghz i suggest you may get a cooler and as i am not expert in the cooling parts so ill suggest you to make a another thread regarding cooling your cpu in the cooling system thread :)

Thanks! I'll check that forum out
