I've been considering upgrading with a new motherboard, RAM and CPU. But with current gen DDR5 having mixed reviews for my usecase, and PCEi 5.0 M.2 SSDs not hitting the market yet, and both Intel and AMD feel pretty lackluster in current gen CPU, and the upgrade to a 4090 blew my entire budget, it just does not feel like the right time to do so.

Pair that with Windows 11 as well and overall, nothing’s encouraging but discouraging.

Also, where is DirectStorage for Windows 10??

My entire budget is like 1/3 of a 4090...

My frames and every benchmarknscore went up 30% on my 4090 when I upgraded from the 5600x based system I had it in at first.

You’re massively bottlenecking yourself most likely. My cinebench is 40k now, Timespy 30k on a 13900 and ddr5

Was it more of a RAM or a CPU bottleneck you think?

I had fast DDR4 in the old rig so I’m pretty sure it was CPU related. I don’t even have XMP on in this new rig, it runs everything maxed out in 4k at 120 fps so I haven’t bothered.

Was the PCIE gen the same?

Gen 5 has 2x the bandwidth as gen 4. Rather than memory latency, bandwidth is usually the chokepoint for most memory related things.

This is it. The 4090 can use those faster PCIe lanes.

Edit: I concede that this is not it. Looked at others' demos and none showed more that a 5% improvement with a 4090 on PCIE 3 vs. 4.

The 4090 actually only supports PCIE Gen 4.0, so those getting fancy PCIE 5.0 motherboards will not gain any performance over the GPU. That, and I believe (really not sure on this) 4090 is not capable of saturating the 4.0 bandwidth. OP could’ve had his 5600X in a PCIE 3.0 build, though.
