The 9800 GTX TOP from ASUS doesn't disappoint in the performance department with it really able to nip on the heels of the more expensive GX2 in most places, bar 3DMark06.
While we understand that it's possible to get most 9800 GTXs to the speeds ASUS has given us out of the box here, some people simply aren't interested in mucking around with overclocking programs to achieve the clocks. Sometimes it's just easier to get a fast card out of the box and know that if something happens with it, you can just turn around and get another with the same high clock speeds.
It would have been nice for ASUS to include a game with such a high-end card, but really, what the TOP series is all about is performance and it knows what it's doing in that department. While it's one of the more expensive brands with a three year warranty versus two that some of the cheaper brands offer, along with the massive out of the box overclock, the ASUS 9800 GTX TOP purchase isn't going to be too difficult to justify to some people.
While the more enthusiast orientated person will prefer to go for the cheapest card on the market and overclock it themselves, people who don't want to have to worry about messing around with overclocking software will find the 9800 GTX TOP a treat. With great availability, a justifiable price and the performance of the dual GPU GX2 in some cases, it's going to be an easy pick up for people who want to get a good bang for their buck.
