If possible, that is a relatively inexpensive expansion. That's why I suggested (and now suggest even more strongly) that the OP investigate whether system memory can be increased. But the fact that it finished the task, even if it did take 45 minutes to me points out a general system overload.the fundamental capability to do the job is there. There's a lot we still don't know about the OP's system. So my suggestion is the list your system here so we can quit guessing we need to know your operating system we need to know your memory we need to know your CPU what it does it's clock speed we need to know your graphics card. You are using up a whole lot of your memory to where it's slowing things way down so that's the first thing you need to do, is upgrade your memory maybe you may have to upgrade your complete system I don't know how old it is, graphics card, as long as you have a decent one is okay with Lightroom Adobe products I don't know about topaz other than topaz is a worse memory hog than Lightroom and Adobe products and you're running it all together you're just out of memory your clock speed may be too slow a whole lot of things could be wrong. This is not a graphics card problem, it is a memory problem. Without knowing your system memory CPU the speed operating system and all of that you're going to get guesses all over the place, including mine. Affinity is fast, no delay in switching modes, etc. I installed a Intel(R) Core(TM) i7-10700F CPU 2.90GHz 2.90 GHz processor.

I used a Nvidia Quadro P2200 graphics card, which is more geared toward photos than gaming. I just had a new build finished this past February. Do any of you folks out there have any ideas as to which card I should get? I'll welcome your feedback.I have installed Topaz A1 Sharpen and Denoise. I was given a choice of three different graphic cards to chose from. I was told that I need to upgrade my graphics card. I spoke to the shop that services my computer when I have problems. With my Topaz products it takes me anywhere from anywhere from 45 minutes to over an hour to process one frame! Even my Photoshop and Lightroom have slowed down, but not as severe as Topaz. Since I bought Denoise all my photo processing software has slowed down to a snail's pace. I have installed Topaz A1 Sharpen and Denoise.
