So I want to get a new computer since mine is old and also wana update it to windows 7 and I found couple of choices. I found this 320Gb Hard drive and 3G Memory for $300 and also this 1TB hard drive and 8Gb Ram for $500. I don't care much about the Hard drive since if I get the 320Gb one, most likely I would also get and external hard drive of 1TB or 500Gb. but what I care is the Memory. the one I have now is a shitty probably less than 1Gb so 3Gb memory might b good but, how good is the 8Gb memory cpus? I know it will be better than the 3Gb one obviously, but can someone give me an example of whenever you run a program on the 3gb and the 8gb?
