My gpu on my iMac 2010 is old and have multiples problems.
the power supplie too is overheating all the time.
I want better performances and update my iMac to a latest macOS version and use it like it was new.
Wich GPU PSU and CPU do i have to buy and from where ?
iMac 27″, macOS 10.13
No matter what you do, it will still only be a 2010 iMac that will only run 10.13 High Sierra.
Instead of throwing any money at that iMac, your best bet is to replace it with a newer or new Mac.
If you are not keen on the new 24" iMac models, then consider getting a new Mac mini and a 27" aftermarket external display.
My bespoke 2010 iMac 27 (max specs) died in 2018 and I found then that replacement graphics cards (uses a special card and heat sink) that matched the performance of my old card (Factory Radeon HD 5750 1GB) were, for the most part, rare and those that were available were in the US$400 range used—six years ago!
Recently I checked my usual suppliers and cannot find any from vendors I trust.
Time to let it go.
As per the Apple Support Communities Terms of Use Agreement, we can not discuss Hardware upgrades or macOS System hacks in this forum.
Simply put, the 2010 iMac does not have the hardware and can not be upgraded to run any of the latest macOS versions.
That 2010 iMac would have come with a 1 or 2 TB mechanical hard drive, and/or a 256 GB SATA SSD. Both would be in SATA-II drive bays, which would limit the sustained transfer speed of the SSD (if you had one) to 375 MB per second, minus overhead. Your iMac does not have USB 3.0 or any flavor of Thunderbolt. A SSD in a FireWire 800 enclosure would be faster, in some ways, than an FireWire 800 hard drive – but would not deliver the performance that people associate with SSDs. (I know that from first-hand experience.)
If you're accustomed to starting up from a hard drive, you will be rather pleasantly surprised at the difference that a fast SSD makes.
CPU performance doesn't tell the whole story when it comes to system performance.
For some tasks, the person sitting at the keyboard, or the slow mechanical hard drive, is the bottleneck. Once you have started up your computer, and your word processor, and are working on a document, chances are that even a 27" 2010 iMac will have no problem keeping up with you.
That said, on single-core CPU benchmarks, a M2 or M2 Pro Mac mini would be about 3.8x to 4.2x faster than a 27" 2011 iMac. A 24" M3 iMac would be about 4.4x to 4.9x faster.
On multi-core benchmarks, any of these Apple Silicon Macs will beat a 27" 2011 iMac by at least 4.2x. The fastest M2 Pro Mac mini would beat the slowest 27" 2011 iMac by a factor of 8.8x. In order to get the benefit of the speed, you would need a job that can keep a CPU busy for a while, and that can also make good use of multiple cores.
Multi-core benchmark scores (from MacTracker)
I used a 2011 iMac as a baseline because there were no scores for the 2010 one in MacTracker.

Support for Metal on Mac, iPad, and iPhone - Apple Support
Metal is up to version 3 now.
Based on this list, it looks to me as if all of the Apple Silicon Macs support Metal 3 when running Ventura or later. Judging by the description of the M3 MacBook Air, it sounds like the GPUs of Macs with M3-series chips support hardware-accelerated ray tracing – something that might be of interest if you are a gamer.
I saw many old iMacs on internet running new macOS versions. There is ways to install new versions but the computer will crash if there is no good hardware.
Yeah I understand, but thanks for the reply anyway.
You're welcome.
