Right;
A. We don't know the exact power requirements it's all in the air.
B. No one know's how hot this card will run in comparison to the GTX, there has been NO talk of this.
C. It may have same or better performance than the GTS but its the price/performance ATi are going for on this card, offer a card that can beat anything NV have out atm for the price of GTS.
D. Not one single game uses more than 512mb and that won't change for this year, frankly im glad to be offered a cheaper card with less memory that I don't really need.
E. The HDMI sound solution is meant to be used for a HDTV, not a monitor. No body know's much about this yet, I'd wait for more confirmation about it.
The fact is ATi are offering this card which will either be the same perf or beat the GTX for the price of GTS, they wouldn't have been able to do this 9 month's earlier. ATi are also offering much better IQ with this card (24xAA) etc. Im all for it.
