If you do decide on 7,get the X64 bit version that i listed,The x32 bit has a 3.25gb memory barrier which you dont realy want if you have 4gb of ram,or plan to upgrade in the future.
ok thanks but i think i'll wait for 7 to be out for awhile to make sure there aren't any problems with it like vista had in the beginning...also i found a xp version cheaper while waiting on someone to answer...can someone let me know if this is the full version and if it's a reliable site http://cvcwholesale.com/index.php?productID=148&gclid=CPDs0aLhxZ0CFYNX2godLXX4sA
