B450 PCI gen 4 support

[Soap007]

Will my b450 support the new PCIE gen 4 nvidia 3070 card and if yes will there be any bottlenect caused by the same?

My processor is ryzen 5 3500x

PCIE is backwards compatible, the 3070 will work fine in your pcie 3.0 motherboard.

I am afraid that my PCIE gen 3 motherboard wont provide the transfer speed that a graphic card with pcie gen 4 would need like sort of a bottleneck.

Thank you for clearing my dumb doubts

Nvidia benchmarks on their official slides were performed on an i9 cpu, meaning they were tested on pcie 3.

If pcie 4.0 changed so much about the performance, they would have tested on pcie 4 hardware. 

 

Also pcie 4.0 is not that much faster, only 2x.

But just wait for the benchmarks if you really worry that much about it.

if you wanna get 3080 or 3090 you may need a gen 4.

but for 3070 which has the same speed as 2080ti (which doesn't need gen4), you'll be okay.

Wait for reviews before deciding.

I was about to write a new post, but this answered half of my question so I'll try asking the other half:

 

Should I sell my 1080 Ti for a 30xx card having a B450 mb with a Ryzen 3600X? If yes, how much should I charge?

Edit: I think I should also buy a new PSU with that. I have a 550 W now
