yea mate, but you know technology is not a problem... the software is - it is realy difficult to make an os that uses 8 or more cores smart, that can arrange and address more than 8GB of RAM and etc. and especialy the BUS, usualy the two things that slow any computer is the BUS speed and the HDD speed. Even if processors are a lot faster BUS speed is still only 200MHz (quad pumped to 800 and with hyper transport to something above 1000) and CPU clock is 3GHz so u realise that less data is transfered to the CPU than the maximum it can handle - so the cpu isnt used at its full power even today. And dont make me start about the HDD, if the actual speed of the CPU's since the verry first models is multiplyed by 1500 times, the HDD improved only 15 times in speed, so the reading of stored data is verry slow, and even scasy HDDs on 15000 rpm in raid mode are slow for the other hardware....
So lets just say that it's not the CPU, RAM or VGA that needs improvement but rather the OS, and firstly the FSB and HDD
p.s. Sorry all if this is a little off topic
