[SOLVED] Is a gtx 750 ti bottlenecking an i5 4670K?

[Batty]

So im planing to upgrade to an i5 4670k and i'm wondering if my gtx 750 ti will bottleneck the cpu. If so, can someone recommend me a better GPU, under 100$, doesn't have to be new

 

[j121]

radeon rx 560 or GeForce gtx 960 both under 100 s on AliExpress.

So i

radeon rx 560 or GeForce gtx 960 both under 100 s on AliExpress.

So it is bottlenecking, thank you very much

Yes , total bottleneck , get a RX 570 , they are good enough and most of the time under 100 $

Your CPU is held back by your GPU, however i wouldnt call it a bottleneck.

Your best bet under $100 is a used rx570, 470, or 480. The 570 and 480 offer gtx1060 3gb performance with the 470 slightly below.

What is the make and model of your power supply? The 570 needs a decent PSU.

neither are very high speed parts by todays standards. 750 ti is a bottleneck however. Make sure your PSU is good enough for a power hungry AMD card before shoving it in your system.

Thank you very much for your quick responses

The RX580 is about $185 currently, and is still a 1080P power house, still outperforming the GTX1060 (6 GB) in most games... (many other lesser 1080P cards need reduced video quality settings to keep good frame rates)

WHen you get a new CPU/MB/ RAM combo (sooner than later, given the state framerates with most of 4c/4t CPUs in games these days), probably a 3600 or 3700, you can take the RX580 with you knowing it's still a great 1080P card..

Yeah but i have to change the ram, mobo, and the cpu, quite a spending, you know

No, absolutely not. There's no possible way that a gpu can ever bottleneck a cpu.

The cpu pre-renders the frames, as many as it can according to the processor speed, IPC, game code. It then ships those frames to the gpu. The gpu can either have the ability to surpass those frames, or not, depending on detail settings and resolution.

If the cpu sends 100 fps to the gpu, then that's the limit, if the gpu can only put 50fps on screen, that's not slowing the cpu down a bit, the gpu doesn't affect cpu performance at all.

All you've got pairing a gtx750ti with an i5-4670k is a cpu that in most games will not have an issue giving more fps to the gpu than the gpu can put on screen.

Adding a stronger, more powerful gpu will not increase fps from the cpu, it'll only increase fps on the monitor upto the limit of the cpu.
