eVGA is much better than any other brand out there because of 2 major reasons....
1. eVGA has a ridiculous warranty stating that unless the card is delibrately and physically DAMAGED, they will fix/replace it for the cost of shipping for life. That covers personal overclocking! eVGA is THAT confident in their product. They wage it against our own stupidity errr...demand. So go ahead and set the speeds as high as your temperatures will allow.
2. eVGA has a step-up program for 90 days after the purchase date of a new card from a credited distributor such as NewEgg.com. So if they G71 or even G80 pops its head out during those 90 days of your purchase, you can cash in your card and snag something different for the price difference.
Overall, eVGA dominates this Video Card industry with amazing service, warranties, compatiability and price. Besides, eVGA always seems to out-perform other brands of identical cards on benchmarks despite the stock speeds. So eVGA is the way to go...hands down.
