Okay, after reading the 30 reviews on EGG, I am ordering the
SAPPHIRE 100357LP Radeon HD 7750
Several reasons for the decision:
1. With a rebate, it's $10 bucks cheaper.
2. It comes low profile, so no need to modify the bracket for my machine
3. It's width measurement is smaller, so it will have a better chance to fit into the case.
4. It has more reviews, all positive, so maybe it has a longer track record/more popular.
5. It did not have complaints about stability with a low number PSU, in fact reviewers reported that it ran well with a low PSU number. The Power Color card did have one complaint about insufficient PSU causing crashes.
I will install as soon as I receive it, and will get back here to report.
Thank you for your recommendation.
