[citation][nom]thackstonns[/nom]Why cant they do this entirely through stream. Why would I have to buy a direct x 11 card for this. My 4870 is still good enough, and I dont see Ati making a chipset for netbooks, so how does this really help anyone. So instead of maxing out a 65 watt part I can max out a 265 watt part. Im not an nvidia fanboy I have ati, but I just can't see where this is relevent.[/citation]You may not be a fanboy, but you are poorly informed. DirectX 11 (software) will include Compute Shaders for DX 10+ cards (hardware). DirectX 11 cards will be able to run CS 5.0, DX 10.1 cards will run CS 4.1, and DX 10 cards will run CS 4.0.
Also you are mistaken about power usage of these cards. When accelerating something like Flash using CS, the chips will probably run at a considerably lower power level than max. Probably near their idle wattage, which on the 5800 series is extremely low. The future lower end 5xxx cards should be even better. For the record, Nvidia cards are a lot more power hungry at any given performance level, currently.
GT300 is going to be very large, so it may also suck up a lot of power like its predecessor. I don't think GT300 will scale down quickly, so a redesign of the GT200 on a 40nm process might be a good idea for Nvidia, especially for the low-cost and low-power markets, and would complement GT300 well.
