hey do you think i should buy a base model 2009 mac pro and then later upgrade the gfx card and ram for xmas and later than that (probably next year) upgrade to the xeon 3580 or should i wait to see what the new mac pros have in store? cost is a big factor and ive considered the i7 imacs but i need expandability. id rather pay now than in 3 years need a new computer. so basically what im asking is how much do you guys think the base model 2010 will be and what do you think will come standard on the base model?
