Well, I am a little confussed (my normal state) - I have read a couple of review and in PC Gamer Mag they gave the card a 83% (not bad) and saw 10-15% performance increases in some games like WOW.
OK, many mags are owned by the advertisers, but they can only stretch the truth - if there isn't some performance there then it would be obvious.
So, it seems to do something. It is a co-processor, so it is processing some instruction so the CPU does not have to - that must help.
You (several of you) talk about getting the same performance increases without having to buy the card (can someone list them), but how can you get the benefit of co-processing?
I am thinking about this card since I am a WOW player, but if I can save $289 I would do so, but if I can spend it and get an immediate performance increase, I would have no problem getting it.
