What about something like Stone Giant? 5870 gets like 40-45fps on that where a GTX480 gets 85-90. One of those is playable, one isn't.
For people who get a graphics card and keep it for several years, the GTX400 GPUs will likely shine much brighter than HD5000 in the long run.
I personally agree with you though, I would never keep a GPU that long. I have a bad habit of upgrading with each generation, but this time I will probably pass on HD6000.
I say that because Fermi holds the same performance advantage over Cypress at all levels of tess, this includes no tess scores as well.
Basically what I'm saying is, they both take equal performance hits at varying levels of tess.
But yeah, in 3 years Fermi will probably perform better in more games, hmm kinda like now.
Haha yeah... scaling is really good with just two, but three it drops quite a bit IIRC. It's been a while since I looked at any benchies though.
I was originally gonna get an i7 or Phenom II with an HD4870/90 back when they were released, but decided it wouldn't really have been an upgrade (at least gaming-wise) unless I opted for two cards right off the bat. I can't believe how long these 8800's have lasted in terms of performance... I still play most of my games at max or near max details. They have started to show their age though in some of the newer titles so I think I'll finally have to stop pushing back the date and spring for a whole new setup sooner than later.... i7 + HD6870 sounds good though.
I remember getting 300fps in Source games with mine.
