I found a benchmark comparison between the GT540M and a $250 Nvidia desktop card:

GPU benchmark comparisons

As you can see, depending on what exactly PS uses, the difference could be very substantial.

On the other hand, it's possible that the problem is not raw speed but actually that the GT540M doesn't have access to enough VRAM to load the entire file into its frame buffer. I know Dells with that series come with either 1GB or 2GB, which is enough for most people but you are working with 4GB files.

You can get decent desktop cards with 4GB fast GDDR5 RAM for around $300, but the 6GB cards jump to $1000 or so.

I'm not totally convinced the video card and the VRAM is the problem but I think it's plausible. In either case probably best just to try before you buy if you can find a way.
