First Computer Rig Question?

try getting windows 7 64 bit if you havent 64 bit windows uses the 64 bit processor's full potential and try upgrading to a seagate momentus hyprid hard drive or if you have the money try getting a solid state drive which is 500 dollars for 250 gb's on ebay Solid state drives do not use disks like a hard drive, they use ram chips to store data so you can get bit rates up to 500 MB/s! instead of 100 mb's with hard disks
