Ultimately, the 9800 GTX+ is just an overclocked 9800 GTX and an overclocked GTX+ is a 9800 GTX overclocked even more. ASUS' decision to offer an overclocked GTX+ from the word go seems to be a good idea as it helps it stand out a bit more from just a regular GTX or an overclocked GTX.
There isn't really a whole lot to say about the card; it's going to come in at a good price while offering some good performance. It's going to fill in the gap that's present between the GTX 260 and 9800 GT since 9800 GTX stock has become quite limited.
The only problem at the moment is the card is quite hard to get a hold of. While there was an official date for the lifting of the NDA, there was never really any word of when the stock was going to be arriving on store shelves. It seems like stock is beginning to show up at places and over the next few weeks we should see more and more stock.
While samples of the card are going to get out to websites around the world, everyone is really beginning to focus on the HD 4870 X2 which is just around the corner. The positive press from the HD 4800 series already on the market means that people are very keen to know what the new HD 4870 X2 is going to offer over the top GTX 280 from NVIDIA.
At the end of it all, the 9800 GTX+ TOP is a good performing card which should show up at a decent price level. It would have been nice to see stock earlier, but that's not ASUS' fault. We're not sure if it was a matter of limited cores or getting rid of the original GTX that slowed the release of the card down, but the good news is it's coming very soon now.
