i5 750 and Modern GPUs

post #1 of 14
Thread Starter 
Hello, i own an i5 750 stock clock CPU and a motherboard that can support the PCI Express of a modern GPU. I would like to ask if a "low" high-end GPU like AMD 580 or GTX 1060 can bottleneck? Assume heavy games such as DOOM.

EDIT: I know that it is an old system but I think it can support me for quite some time. I have a stronger PC but this one is going to be placed at my vacation house.

I'm not sure about "bottlenecking" because I've not run any benchmarks, but my son has one of my old rigs and games on it daily with a stock i5-750 and a 970 GTX at 1080p. He never complains about performance and plays mostly online shooters (Overwatch, etc). For a vacation house machine I think it will work great, just don't get too hung up on max settings.

I've got a friend who is still rocking an i5 750S in his rig with a GTX 1060. He mainly plays overwatch and has never complained of any issued with low performance. Its an old chip, but it does still do its job. A 1156 Xeon would be a solid and cheap upgrade that would give you a bit more performance it you wanted it.

Thank you very much really helpful. I am not going for monster gpus but something between mid-high range gpu so your answer cover me.

To tell the truth I have no purpose to spend more money except for the GPU. Recently I acquired a Mid range tower to fit any upgrade I bought but I got low in the budget because I spend spare money on other more important sudden needs and i "left 4 dead" with the PSU, New Tower, and a Hybrid HDD-SSD. So I saw that I could buy a GPU about 200-230 euros and I want to buy a modern GPU as the old one is a Sapphire HD 6850 1 GB. Old enough,fine for popular online games but not so enough for most modern single player games for medium settings and decent fps. To give you an example I want to buy gtx 1050 ti.

1050TI's are great little cards, you can easily drop them into a cheap office style computer given their power requirements and have an ok 1080p rig on the cheap, like the one in my sig (albeit it's mining and 2 x 1050 ti's don't sli).

there is a bottle neck, just not to the point of severe diminishing returns. a 1060 would be walking a fine line with that statement and I would strongly recommend a step down. the stock 2.66 is very low, is overclocking an option at all?

You'd get pretty similar performance with a 1050ti on average, it would be a sensible option. Games that mainly stress the GPU would be the only ones to benefit from the 1060

Witcher 3 would be the type of game with a pretty noticeable bottleneck. Doom would go all-right, not great. it's pretty forgiving to CPUs and slams gpu, but again, there will be a bottleneck (and many frame drop spikes though decent average).
a 1050ti would be a "better" choice for a sharp price to performance especially in your circumstance.

check out this vid where he tests a 1080 but has a nice 3.7 ghz overclock on his i5 750 https://www.youtube.com/watch?v=TScpVAGNdcI
again, on OC would help lol

I watched videos before posting here this one included. No overclocking is not an option. The motherboard is like a time bomb I don't know when will be dead and the state it is now ( that is very old ) i think is bad for overclocking. Going back to my requirements i just hope the games to be playable at about 60 fps even if that means low settings.

Just overclock it. Quad cores aren't really sufficient for >60 FPS any more, but overclocking an i5-750 to ~4.0 GHz will land you at around 60 FPS minimums in modern games. Anything above a GTX 1060 or so probably isn't going to be particularly beneficial because you'll see framerates fluctuating dramatically at 1080P. At 4K, you can probably justify a better GPU to pair with it.

Perhaps this is a more relevant link
https://www.techspot.com/amp/review/1325-intel-pentium-g4560/page4.html
The g4560 is the closest modern day cpu 750 on the tomshardware hierarchy chart, so should be very similar performance. As you can see, the 1080 is heavily bottle necked across most titles. The 1060 bottlenecks, some titles benefits, but the cpu intensive games knock it down to the 1050ti. Also worth noting is the large gaps between minimums and averages. That would be some pretty choppy stuttery game play. The minimal differences on the 1050ti would be a more enjoyable experience overall.

I'd personally be happier with the 1050ti if I were in your position, it's $200 cheaper. So I'd get that, a case of beer, a new game and still have $100 bucks to spare/put in the future upgrade budget.

Edit: you could also upgrade to a xeon x3470 for under 100...
