You are about to be CPU bound. My old 2700k at 4.3-.8 Ghz is sometimes bottle-necked by an rx480 8Gb. I can still use a beefy card in it for compute though. Looks like that card can saturate your PCI bus at 3 - 4x the throughput your CPU can handle. I would consider this if you had a need right now and you are going to upgrade the rest fairly soon.

What this guy said, welcome to the world of being CPU bound.
That being said, unless you are going for benchmark scores you most likely won't run into any issues. There are RARE instances that because of the nature of the bottleneck the systems actually operates worse than previously but thus is a vary rare occurrence. You will definitely be not getting the full performance of your GPU though.
If I'm not going to be getting the full performance of that card, should I consider buying an older card instead, if the older card would be just as fast in practice?
(How can I know the effective performance of a video card on my system?)
I have a PC of theseus. My CPU and GPU get swapped out on alternating 3-5 year intervals. I buy the best GPU I can afford KNOWING that in a few years I'm going to be upgrading my CPU. My computer is an eternal bottleneck.
If you just plan on keeping everything as is for as long as possible then getting a less powerful GPU would hurt you at all. It would save you some cash.
No you really should get the best GPU you can afford. Yes you will be bottlenecked, but only on more recent games where game devs are really trying to squeeze what they can out of the latest Xbox and PS5.
CPU upgrades are relatively cheap compared to GPU upgrades as well.
No, don't listen to those who're so scared of being Bottlenecked™. Unless your upgrade is hilariously lopsided (like buying a RTX 4090 for an Intel Sandy Bridge platform), it's likely to be the best upgrade per dollar spent.
Do think about your upgrade path in the future, like, are you planning on an entirely new PC soon? The other factor in an upgrade is also the dollar per time value; no point spending $200+ when you're getting a new PC next year, for example.
I went with a GTX 1070 for an i7 920, that extended that platform for another 3.5 years. Played quite a few games too. Carried the GPU into the new system for another 2 years! Pascal was truly an amazing generation.
my friend played baldur on a 960, it is capable of handling the game if money is tight
You could use that GPU no problem. Not sure about bottlenecks, but it would work.
Hey, my friends just bought a 7600 for our friend who was running the same gen CPU who had a GTX 680ti. The upgrade was so large that any chance of being CPU bound was overridden by how.much more powerful the GPU is. He also had 0 issues upgrading.
The reality is that most games (CS:GO, cities skylines, etc.. excluded) are heavily GPU bound. You will see a huge upgrade, be able to use the AV1 transcoder, AND get another minor upgrade when you upgrade your CPU/Mobo to something with gen4. (There is a 5-10% loss with PCI3.0).
We are trying to see soon if his build can handle Baldur's gate 3 with the 7600. It is around the same as a 5700XT and it works fine with BG3.
I did similar recently. Upgraded from an RX580 to RX6650XT on an i5 9600/PCI3 board. It's definitely an improvement, but not as much as I'd get with a new mainboard+cpu.
You'll likely bottleneck in most games, but it'll work. If you run into stuttering, limit your fps.
As I understand it, the socket on the CPU changes every few years. Intel is on a socket called LGA1700 now which will support 14th gen but after that it will be a different socket. So any motherboard that has LGA1700 can be used for now but later new motherboards will be released for the new socket. Similarly in AMD, the current socket is AM5 which they've said they will support for another year or something, after that the new CPUs will be on a new socket.
The above matters for choosing a motherboard that will be supported later by new CPUs. For GPUs the socket doesn't matter, but the higher the PCIe I suppose that's better.
I'm a beginner at this though, and may be wrong, but you could search more along these lines. Hope this helps!
