Any thoughts would be appreciated. There are sacrifices to each system to keep costs similar, for example the Intel one its a single 1GB HDD (but Sata6) but for the AMD I could have two 750mb mirrored (but Sata3).
Purely on the hdd's alone I would choose the twin 750's,that way if something goes wrong you have backup. As to whether AMD or Intel is better for gaming,I love my games,mainly FPS's and have played mainly on AMD chips.My current rig,a self build is an i5 with twin HD 5770's and runs all my games maxed.
There isn't much difference between the chips, compare here click here There isn't much of a performance increase with sata 6,so I would go for your second choice.
