Solved Hardware question, seeking graphics card upgrade for Acer X1420G-U5832

I know I'm not the only one that's sought to upgrade this particular computer, having seen two previous threads here about the same computer and an upgrade involving a Sapphire ATI Radeon 5570 HD. I know that will work without much issue. However, I want to see if I can go further with the same minimalist upgrading. Because of this, I made an account here in hopes of getting some answers.

I am currently looking at this card, also from Sapphire. Only, this one's higher end, being a Radeon 6570 HD found here. For those curious about the 5570 HD, that's here. I have looked at its benchmarks and it looks promising, but I have two questions.

First, is this a sufficient upgrade compared to the HD 5570? It's only a few dollars difference, but I'm seeking the best performance that I can get without doing a ton of upgrades. Second, it looks like it'll fit (looking at the card, it seems to be a low profile, which is necessary), but if anyone has the same computer, perhaps one can be a better gauge of that? Thanks for any answers anyone can give.
