I don't buy expensive computers anymore i have in the past but then i just gave it away doesn't matter how much i spend or the specs & model computers for me = crashed & burned at the 2 year mark. I know just buy realtively cheap systems with good specs - the whole computer world grows so quickly these days & even the best system is outdated & superseded very quickly.
On that note my computer is getting pretty squeezed ATM and the 2 year mark is getting very close so while i haven't been hunting so can't offer any suggestions - i really should be about now - thanks for the heads up.
