7900X vs 9900X

[Belezeebub]

Take note I said X not K not sure why Intel made a 9900K and a 9900X but I digress.
I have a 7820X De-Lid and LM on an MSI M7 ACK board I have a full water block and the CPU is good and stable at 4.6Ghz with temps on my water loop I am happy with. I don’t need more speed I do need more lanes.
I have an MSI Aero Xpander x4 I have been dying to try but fully loaded it wants 16 PCIe.
I have a few options
 

1. Keep my gear put the Aero in the X16 and my 1080TI in PCEe 8x I might lose a few points
2. Drop a 7900x into my Motherboard and I can go full 16x16 I have a buddy with a DE-lidded and LMed 7900 I can pick up for 800 and a 6-pack.(the 7900x comes with a Strix E so I could sell it with my 7820X)
3. Purchase a 9900X just a tad faster just a tad more L3 newer and a tad more stock and Tb speed but about 18% more power draw, but brand new it’s the same price as the 7900x (no delid and no LM, but soldered if my research is correct so I might not need it. But reviews on the 9900X are Few and far between and they are hard to find for sale.

I do large Video trans-coding and video editing maybe 40% games

GPUs do not need PCIe x16.

8x is more than enough bandwidth.

I fully understand graphics don't need 16X which is why my first option was to put the aero in PCiE 1 I was hoping to get input from people with similar setups, two extra cores might also help on my work

I almost went with a 9900X build, at the time I was doing my build they were out of stock along with the 9800X, ended up going Z390/9900K instead.

 

It is really frustrating how much of a lack of reviews there are on all X299 board 9-series processors there are.  It's practically impossible to find much information on how well a 9800X/9900X/9920X overclocks compared to it's predecessors, or anything like that.

 

If I were you, I'd upgrade for the cores etc.

Tell me about it even finding the 9900X for sale is like pulling teeth, it gives me pause maybe they are rare because there is an issue with them.

Second question 

 

I have the MSI M7 ACK X299 Mb My buddy is making me a sweet deal 800 bucks for his 7900x and his Asus X299 Strix MB or 1.1k if I want his 64Gb of DDR4 3000 I am considering it but not sure which is the best board.

 

The Only feature the Strix has my Ack doesn't have is a ARGB which does appeal to me a little bit
