+ 1 for 7970 - Single GPU options are always king - Ive been an SLI user since 2007 - not been single GPU since then. I cant wait drop one of these in my rig - No longer will I have driver support issues and games that simply do not understand that I have 2 GPUs.
On another note - If you fancy going Xfire with these in the future, say hello to
acceptable framerates @ 5670x1080 with AF+AA
- something that has previously been impossible without Tri or Quadfire 6970s (imo)
