The Scan machine spec statees:
NVIDIA GeForce RTX 3070 Laptop GPU
While the Box machine is showing:
NVIDIA GeForce RTX 3070Ti 8GB
It's that "ti" that makes the difference - not all of the £300 but a chunk of it.
Sorry, I have (understandably) confused you. My earlier post was comparing two differnt machines and asking what the difference was. But following up on your suggestion to try building one up on the Scan site, I actually found what I thought was the same Box Acer on the Scan site for the same money - hence thinking myself an idiot for having missed it previously. So that was my last post. As a couple of you have now confirmed that I posted the same machine twice (but from two different sites), I am happy that the wall of specs and numbers was talking about the same machine. So I will go with the Scan option (especially as it has this Ti doodad, which while a mystery to me is better). Thank you & sorry to have confused your otherwise-lovely thread with my incompetence. I have caught up, now, finally. Thank you.
I think he was replying to a few comments. The last two links you posted are identical machines.
If pricing is reasonable, one will always want to choose a Ti version of the RTX card over the non-Ti.
Keep in mind, it's still a laptop GPU, so it's not going to be as powerful as its desktop counterpart. This laptop GPU draws 150W of power while the desktop version draws 290W. This will directly impact the card's performance. But, it's still a GREAT card!!
Thank you very much, you're quite right. And thank you for the feedback. Given I also need to do a bit of work on the machine, and sometimes work from our house overseas, I'm stuck on the laptop route (which reduced my usual poor knowledge of PC's to remedial knowledge of laptops). I will buy the Scan machine and stop pestering now.
Thank you both, for both responses and patience. Appreciated, Commanders. o7
