Well I would definitely go with the second one, seeing as it's pretty much the same but with higher quality components... I would do a few things though.
-Change the PSU. A Xigmatek Asgard II and Antec 380w PSU are good together, costing about the same.
-Get a mobo with USB3.0 and SataIII for upgrades later on (ie SSD or large external backup drive)
Could i get by with a triple core or dual core proc? or will the quad core be almost necessary? Also if quad core is the way to go, should i spend the extra 5 bucks to get the Phenom II over the Athlon II?
