How can I make the smudge tool faster?

What's the hardware that affects the smudge tool's speed? I'm about to buy a new machine to use Photoshop on, and I'm regularly working on documents that are very large (an average is a 24"x16" image, 7200x4800 pixels) and I'd love for the smudge tool to be as responsive when my brush is 400 pixels wide as it is when it's 60 pixels wide. I'm wondering what to invest my budget in: a faster CPU, more RAM, or a better GPU? Or a blend of all 3?

I don't know if I'm asking too much and everyone has this problem when the smudge tool gets that big, but as it stands right now I'm usually left with my stroke coming in slllllooowwwwllllyyyy while that blue donut keeps going around and around. Thanks!

You'd have to get faster RAM -- the Smudge tool is somewhat limited by the speed of the CPU, but mostly limited by how fast data can get in and out of RAM.

A 400 pixel wide brush is moving 44 times as much memory as a 60 pixel wide brush. For them to be the same speed, the RAM would have to be 44 times as fast (which isn't going to happen anytime soon).

More RAM might help some, and a faster CPU.
But larger brushes are never going to be as fast as smaller brushes -- they just have more work to do.
