pcie Pcie assistance please

[Paulino]

So... i have an old desktop that i got from my friend and i have been trying to make it work and now that it works i got confused according to the specs of the processor only supports pcie 2.0

but the motherboard supports pcie 3.0 , does that mean that i need a gpu that supports pcie 2.0 or  does that mean i can get a newer gpu that supports pcie 3.0?

i'm new at this pc builds here are the specs

intel i5 2500 3.3 ghz sandy bridge

8gb ddr3 1333

gigabyte ga h61m ds2

intel hd graphics 2000

No you can drop any gpu into it. pci-e as a standard is backwards compatible.

only in the early pci-e 1.0 and 1.0a days were there compatibility issues that aren't really an issue anymore.

oh... thanks cause I'm thinking of upgrading it to a gtx 1050. Also will that create a bottle neck?

Bottlenecks only occur through usage , not parts simply being in the presence of other parts.

Meaning it depends on how you use the system. If the application is cpu heavy and gpu light then the cpu will be a bottleneck. If the application is gpu heavy and cpu light , then the gpu will be the bottleneck.

thank you kind sir

your cpu and gpu combo are pretty good, i think youll be fine out until a 1060 6gb before you start noticing any real bottlenecking

what do you mean?

Meaning there wouldn't be a usage case where bottlenecking would not occur with any gpu higher than a gtx 1060 6gb.

Essentially it would be difficult to find a task that would fully tax the 1060 6gb and not the cpu.

I kinda disagree with that assessment as anything requiring gpu rendering WILL tax a 1060 6gb fully and not the cpu , but everyones entitled to their opinion.

thank you once again
