I just heard about the new 8 core MP's and have been doing some number crunching and am now seriously considering getting one as my main station. originally i was going to build a PC but seeing as a MP could run both windows and osx its looking like a better option. HOWEVER! there are some stumbling blocks. At first i was horrified at how expensive the ram was, but then once i found that you could buy it 3rd party for nearly 1/2 price i was reasurred so i'm looking at these Thinking of getting 2x4gB kits. so thats solved. second issue was with HDD's If i get one of these will that be ok? On the apple site it says that the drives have no cables and that they fit into some sort of cradle thingy which slots into the case. Would there be spare empty cradles for extra drives, or do the drives come with the cradle? if there are spare empty ones, is there any reason why not to just get a normal sata hdd from any online store, say a seagate (which are usually cheaper)? And finally the biggest stumbling block of them all. why on earth are the gfx cards available for macs so outdated!? As i understand it you have to get a "special" mac video card (which seems to mean less for more $$ ) The best card they offer is the x1900 i have never used ATI's before so what is this card's equivalent in gforce terms? does anyone know if/when the GF8 series will be "ported" to macs? Hypothetically could i install two cards, one for osx and one for windows? say a x1900 and a gf 8900? I've seen some work being done to get PC cards running on macs but nothing seems to go above the 7xxx's already available, whats the word on hacking the OS to get a better card running? Its a real shame, if it wasn't for this gfx card issue the MP would be a no brainer choice..
