The above table shows the vanilla numbers for the individual NVIDIA cards, however most companies tend to add their own touches to their entries. XFX is no exception here as they bump the core speed from 400MHz up to 450MHz and the memory speed from1000MHz up to 1050MHz.

Although some people may not like a card that comes pre-overclocked, I love it. Most people want to just plug in their video card and go, not wanting to risk ruining a $400-500 investment for a modest performance boost. So, in my opinion, the XFX 7800GT already has a leg up on the competition. Add to all of this the “Double Lifetime” Warranty, and the end user has quite a deal on their hands.
