A quote from the article:
>> Gigabyte GTS 250 1GB Review
If you are plan on overclocking however, this GTS 250 would be a better bet against the HD 4850. With the Zalman cooler, this card is able to sustain very fast overclocks, propelling it into a respectably higher level of performance. For those of you look to upgrade soon, the Gigabyte GTS 250 is worth a look, and for the overclockers out there, this card is worth two looks.
