I think the pc would be better than the 360,PS3. Wait for Intel Core 2 Duo(Conroe) this cpu will kill amd top of the line FX 62 at a price range of 300+ or something like that...
never have i seen more uninformed posts crumpled up in a single thread.
the Intel Core 2 Duo is already out, and will cost somewhere in the 800-1000$ range, http://www.tomshardware.com/2006/07/14/core2_duo_knocks_out_athlon_64/.
back on topic,
I suspect that Sony will ride on the wave of their maket superiority which they obtained with the coming of the ps2 through to the end of the ps3 era, although there will most likely be a decline in there market share percentage of gaming consoles compared to what it is now, although still in the lead. I expect that Nintendo will gain quite a considerable increase in their markey share of the consol world simply because of the price point and there inovation they are trying to achieve in the genre. Microsoft will be behind Nintendo and Sony in the console war although this time around the difference between all 3 company's will be less drastic in terms of market share.
I suspect most gamers are going to be purchasing a Wii along with either the PS3 or 360 simply because of the Wii's price.
As for any of the facts on this, we will need to wait until all 3 systems are out.
As for the hardware and what eat system is capable of in terms of visual quality, all 3 will be outstanding. Remeber these are
Gaming consol's (despite what sony might say about the ps3 replacing your home computer) and so they are designed to acheive superior visual quality then what you would expect a PC to be able to achieve if it had the same hardware( although we could never compare this unless all the hardware for each consol could be build into a PC). Your 7900GTX or 1900xtx have amazing visual pumping power although since they are used in a PC where it is expected they will handle more tasks then simply gaming, they cannot achieve the same level of perfomance if the exact same card was put into a gaming console to handle only gaming.
This is why i believe that if nvidia is saying the PS3 will have the same graphic pumping power of 2 6800ultra's (if used in a PC) that the actual perfomance will be greater than even that if used specifically in a gaming console designed to play games!
but these are just my opinions.
