No. My laptop's performace is nice
No, it's really not. It was nice about 15 years ago maybe but not now. You clearly haven't been paying attention to the PC market over the past ten years or so because
According to Passmark, there are 3,094 CPUs ranked above the Core2Extreme X9100 in performance.
Their analysis of that CPU is:
"This is a fairly old CPU that is no longer competitive with newer CPUs."
To give you a better idea of just how bad the performance of the X9100 is, it gets absolutely
destroyed by the AMD A8-3500M, a Llano-based APU that was their first mobile APU and came out 12 years ago. I retired my A8-3500M craptop three years ago because there was no way it would've been able to properly handle W10.
Even just a modest and mainstream APU available today like the Ryzen 5 7530U, is over
THIRTEEN TIMES MORE POTENT than the Core2Extreme X9100 despite having an RX Radeon Vega 7 IGP.

Your best option would be to just buy a modestly-appointed modern craptop because no matter what expresscard and desktop video card that you waste your money on, it will be so bottlenecked by your ancient X9100 CPU that it won't be even worth using. Your CPU is from the Radeon HD 4870-era and even something as old and obsolete as an HD 7970 would be too fast for this CPU.
You're better off just buying a modestly-priced modern craptop with something like the aforementioned R5-7530U at its core:
