Yeah I'm an NVidia guy myself, but that 7970 deal is pretty awesome, and the 7970 is the only ATI card I would ever consider buying.
If you're reluctant, this Windforce 770 is on sale after rebate for $390 at NCIX this week:

The Windforce cooler is second only to ASUS's DirectCUII for cooling/noise ratio, and overclocks very well.
