Best GTX 560 Ti

I've been interested in upgrading my 9800GTX+ for a while now and I just came up with the money to upgrade. I've decided to go for a GTX 560 Ti, which brand and model do you guys think is best. I personally love EVGA for their customer support, but their cards aren't the best performers. The MSI Twin Frozr II is very good performance wise, but I've heard about artifacting issues with them. Which card do you guys think is best?
