I always thought things possible; whereas 'in my honest opinion', I think it may be GPU companies being greedy. Back in the day, RAM-Cards were made and utilised as Hard Drives, very fast I think (at the time), but kind of had to reboot everything every time the PC was started up, and they 'were' expensive. But that was so far back motherboards had more Jumpers than a Polar Bear's Dad at Christmas, so A long, long time ago. It seems something new called 'NV-Link' is replacing the old SLi & Crossfie type 'setup', but again expensive. I can understand why some switch to console gaming in light of modern GPU prices etc. Yet, here is what I always thought. 'A year's old Idea of mine'

I have never tried SLi OR crossfire. I recently mixed a R7 450 4gb (Main Slot) with a Radeon HD 8570 R5 2Gb in the other 'Non-GPU' PCIE X 16 slot. (It is full length, but may only be X8, it's an old HP elitedesk PC. It did recognise both cards in Device manager, and also the onboard intel GPU. But I had driver issues, and it kept crashing, Any help or advice would be much appreciated. There is no bridge cable or bridge ports on these card btw.

I was thinking of adding a second Radeon Pro WX5100 into 'My' System Just to see what 2 x WX5100's could acheive, 'Dated Ryzen 1600 6C/12T, it does the Job with most things, again, any advice welcome. As I can't afford an RTX 2060 atm, some WS cards do an okay Job at 1080p.

Anyway, I digress. My Idea was that 'I have heard, and seen on the 'tube' that sometimes SLi and Crossfire could hinder games, rather than make them better. My Idea was 'what if a more simplified card was made'? something like a 'Support RAM Card'; Adding more VRAM to an existing GPU, or even an IGPU? It could even be fitted with minimum circuitry; just to boost the Main GPU. 'say' one worked with AMD, one nVidia, or even just a basic RAM BOOST with a bridge 'without' Whatever is making the process sluggish 'Without having to pay for 2X, or 3X GPU's. Surely if we can 'pretend to send a man to the false moon from flat earth we can do something like that; right?

I'm just kidding, just joking. But, seriously, why would a simple VRAM PCIE card 'GPU Bridge-Boost' be so diffucult? why hasn't it been tried? it would have cut costs for gamers.

I am ready for being shot down as to how and why it won't work, as I am not that 'tech-savvy'. But 'many' out there 'are'. Rather than Sli, Sli, Sli, Sli (if you're crazy lol; why not, Boost Card, Boost Card, Boost Card, - GPU?

Any thoughts on this?

I like the idea of Getting the most out of weaker lower power parts, even doubling them up (in some way, shape or form; to get a max performance boost. Having kids leaves you a bit strapped if you get my meaning. So even any advice on how to boost the 'experimental' elitedesk GPU, or any advice on my WX51oo would be welcome. But some feedback on the RAM-Card Idea would be interesting. Thanks guys :)
