Will an i5 3570k Bottleneck an RTX 3070 at 1440p Ultrawide?

I'm guessing the answer is yes but will it really be that noticeable? From what I've looked at, the closer you get to 4K, the less difference the CPU makes.

I bought the RTX 3070 (FE at RRP) due to getting caught in the hype but now I'm wondering whether I'll need to spend close to a grand to build a system to make full use of it.

My current PC is over eight years old but feels fast enough for most things; overclocked to 4.2GHz with an SSD and 16GB of RAM.

You can always turn ray tracing on to 'remove' the CPU bottleneck

You could look up some benchmarks to see if CPU has an effect in your game of choice at your resolution, but since you've bought it it's simpler just to try it for yourself: Is your game playable at your chosen settings? If yes, no worry. If no, does dropping the resolution make it playable? If it does, you were not CPU limited. If it doesn't, you were.

If the system feels fast enough, then it is fast enough.

If you feel it starts to chug, then at that point you upgrade and you already have the graphics card.

It really is down to which games you are playing though.

So just enjoy your new toy, and know that come the next upgrade you already have the first component

Edit: Now is a pain in the butt time to try and upgrade as parts are hard to find and expensive when you do find them. Being able to put off further upgrade is a bonus right now.

According to bottleneck calc ;

Intel Core i5-3570K
NVIDIA GeForce RTX 3070
16GB DDR3 1600MHz
1440p Medium Settings
Bottleneck AVG 39.3%

Thanks for this. I didn't consider that a calculator would exist.

Thanks to the other replies too. It does seem like a bad time to buy things.

Im interested in this as I also have an i5-3570k with 16GB and a GTX960 and getting the itch to upgrade. The PC performs well but can't decide if it's worth upgrading. No graphics cards seem available, not anything worth buying and if I invest in an intel 1200 series 10 chip I can't help thinking better to wait until series 11 in March.

that bottleneck calculator is inaccurate. I had low bottleneck % on there with my Ryzen 2600 and 3060 Ti when in reality there's a lot of bottleneck. Your i5 will definitely bottleneck especially in newer games that utilise multiple cores

I did upgrade in the end to a Ryzen 5600x. I only built it on Saturday and haven't had a chance to try any games yet. I never put the RTX 3070 in my old system so wouldn't be able to say how much the 3570k slowed it down.

Here are the components for my new build and how much I paid (over the past couple of weeks):

AMD Ryzen 5 5600x (£278.99)
DeepCool Gammaxx 400 V2 (£19.54) + Arctic MX-4
MSI B550M Mortar (£113.99) - I didn't see the point in full ATX
Corsair Vengeance LPX 32 GB DDR4-3200 CL16 (£131.99) - hopefully dual rank but I haven't checked yet
Western Digital Blue SN550 1 TB (£83.69) - replacing a 250 GB SATA SSD and 1 TB 5400 RPM hard drive
Nvidia RTX 3070 (£469.00) - lucky to get this at RRP
Corsair RM650x (£104.99) - only 20W more than my old PSU but Gold rather than Bronze
Fractal Design Define 7 Compact (£91.99)

Total: £1,294.18 (exc. delivery charges and thermal paste)

I had to flash the BIOS of the motherboard to the latest (non-beta) version for Windows 10 to install (as otherwise it just hung on the Windows logo). It was simple to do and didn't require another CPU as I could just put a USB stick (with the new file) in the Flash BIOS port on the rear I/O panel, press the Flash BIOS Button and wait a while.

I didn't really need the new PSU and case or even storage but decided to just replace everything (except for the DVD drive as I hadn't used it in years). I could've also gone with just 16 GB of RAM again but wanted all the numbers to be higher
