The X1300pro is actually a very fast card considering the price. Certainly faster than the 7300GS, and yet I don't see you bashing that. Here, let me lay out the specs of both of them to you in black and white:
7300GS:
Pixel Pipelines: 4
Memory: 256MB, GDDR2, 64-bit, 533MHz (effective)
Core clock: 550MHz
Maximum resolution: 2048x1536
Price: $99
X1300Pro:
Pixel Pipelines: 4
Memory: 256MB, GDDR2, 128-bit, 800MHz (effective)
Core clock: 600MHz
Maximum resolution: 2500x1600
Price: $99
As you can clearly see, the 1300Pro has a significant advantage over the 7300GS, mainly due to the fact that it has 128-bit memory, and the memory is clocked at 800MHz, where as the memory on the 7300GS is 64-bit and clocked at 533MHz. Not only that, but the X1300Pro's core is 50MHz faster than the 7300GS. AND it has a larger maximum resolution (not that anybody would go that high on a budget card, but still, it's nice to have the option). You purposely linked to an X1300Pro made by an overpriced off brand with a strange cooler. Sapphire is to ATI as eVGA is to nvidia, so lets take a look at what sapphire has to offer instead:

Hmm, what do I see? I see a price tag of $99 and a normal looking cooler. You would like to know who would buy one? I would. In fact, I am getting one for the budget PC I am building for my parents.
