That does complicate things way more, annnnd it sounds like extortion with a side of collaboration. So technically speaking moving to that other job they should be switching you to their payroll if you're contracting for them. If they aren't, then it's 100% a Lockheed situation where the contractor is being paid what the contracting (original) employer is willing to pay them while the main company skims off the top. That would explain the staggered raise as they are paying you the dividend. I'd for sure be having conversations with both companies about this situation and make sure details before accepting anything are on paper. I mean call me paranoid, but I'm still dealing with mental trauma from working at Lockheed dealing with this very thing as is my previous coworker.
In other news, yesterday I had a slight epiphany about the current status of the graphics market. Specifically Nvidia. All because of a toll post in a FB group. Guy said "this is the last rig I ever built, and I refuse to upgrade because of the current corporate greed". Problem is, dude has a pair of 1080s that cost him 600 a piece meaning he dropped 1200 in GPU that he can only use a handful of times in specific games, with microstuttering, drawing more power than a 4090, but won't pay for a much more powerful singular card.
When I typed it out it hit me, pair of 1080s cost 1200, a 2080ti cost 1200. A pair of Titan Xp cost 2400, a single RTX Titan cost 2400. The 2000 series was the shift of price and market structure after over a decade of enthusiasts purchasing 2-4 cards per gen. 2000 series introduced RT and DLSS that doesn't work with SLI tech, and they also dropped support for it with the 2000 series. The 2000 series was a sidegrade compared to the similarly priced 10 series, but it wasn't meant for those folks as an upgrade path unless they went single 2080ti. The 3090 was a significant upgrade compared to 10 and 2000 series though. The internet has been completely blind or unwilling to see the shift in structure, while the rest regurgitate the information claiming over priced and power hungry.
If you sit back and look, the enthusiast side has been buying 2-3 cards as far back as the 8800s in 2007 because of Crysis. 3 8800GTX is 1500 bucks. Some folks (like yours truly) were buying 2 and 3 Titan X cards which gobbled up 900W from the wall with minimal performance benefit in 90% of games. Playing 3Dmark to justify purchases. Even yo schmo won't upgrade had dual 1080s. With SLI being tossed, we've been given much higher performing cards in the enthusiast segment while maintaining a lower power budget compared to dual and triple card solutions. With pricing being about the same when you look at it from a broader point of view.
The big difference hitting most consumers today would be the midrange side of cards but there's an answer for that too. In 2011 people were buying up the 560ti being a 250 dollar card. Being a midrange card you'd be playing at high settings 720p, or lowering settings for 1080p unless you were playing like Battlefield 2. Even with a 580 I was lowering settings for BF3 to get higher frames, as far as you guessed it, going SLI. With folks saying "it'll be fine and you can just grab another 560ti later and you'll be set". Albeit with complications, more heat, and searching for modified SLI profiles for not so AAA games at a total cost of 500 minus PSU. Today you spend 400 on a midrange card like a 4060ti and you're set. 1080p or 1440p, you're set. Nobody is buying those cards for RT, and with DLSS2/3 you can even manage 4k in some titles. 10 years ago 400 got you a 70 series card yea, but you weren't maxing out titles. Who played maxed out at 1080p in BF4 with a 670? Nobody.
The structure changed, and the shift off enthusiast SLI moved to massive monolithic cards for the same relative cost. Again in 2007 3 8800GTX would cost you 1500-1800 (depending on model) and gobble 500W of power stock to watch 3DMark06 be bottlenecked by a dual core slow CPU. Even with inflation, 1600 for a 4090 that will do 100fps in practically anything at 4k seems not so bad. Yet the industry has lead a purposely blind eye to this fact.
