What build would preform better?

The 5400 drive is the drive speed of a laptop drive and it's slow.
You will have a better chance of getting a good build with everyting you want if you give us the budget amount and what parts you need and don't need.
There's also a reason that the AMD cpu is $99 and the Intel 2500k is $219 , there is just no comparison and even though the 570 is a great video card the AMD offsets the quality of it by not being as good. Since BF3 is totaly video card intensive and the two cards are the same level build 2 would be better based on the 2500k.
If you post the budget and what parts you need and don't need maybe we can get that SSD by another way.

^ + 1 from inzone.. ADDING that If you're going to be doing video rendering, coding and editing you would probably want to look at the 4 core/8 thread processors at least.

budget is $750 and i already have the 2.5" drive and a os.

The total for this build comes to $777.92 and is just a little over so if you can find an additional $30 from someplace you can get this build which has a SSD and a six core AMD cpu.
