Thank you for the advise!But I got a noob question here...how much performance would I lose if I switch to the 16M Cache Hard Drive? Also do you think the PSU that I pick is good?

And for the Mobo, would the HD 6850 be able to fit in it? I saw a review from http://www.overclock.net/t/1265107/gigabyte-b75m-d3h-review-with-intel-small-business-advantage, "With this board, since it is mATX, size restrictions require the user to install memory modules before a long graphics adapter is installed."
