Here's your machine dude. I left you a little overhead in case you need a new OS because your going to HAVE to run a 64 bit OS. I didn't fully check compatibility so it's up to you to make sure the motherboard likes the RAM model, etc. but this should be pretty close. OC the CPU to about 3.6-3.8 Ghz and AH full settings should be a breeze.

that's basically my system, slighly different mobo, case and ocz ram and an evga 465 1 gb oc card. and installed a really good cpu fan the Prolimatech Megahalems Rev.B CPU Cooler (recommended by TD). I play everything maxed out with hires pack texture shadows at 4096 (lowered it to 2048 because i really cant tell the difference). 1920x1080 resolution. my fps mostly stays in the high 50's and sometimes will go to the mid to high 40's during large furballs/cv ack. and we are talking about 30-40 airplanes flying around.
cpu is oc to 3.8 and temps only went down to the mid 50's once i got that cooler from the mid 60's at full load. which would sometimes cause my puter to crash.
I am really happy with my computer. but if i was to build a new computer, I would go with and i5 or i7 (think TD mentioned it in another thread). spend a little more to get an upgraded system, e8400 is an awesome processor and dont think an i7 or i5 would be an improvement in ah. but you have to think long term, i mean gigabyte no longer makes my mobo (ga-ep45-ud3p) and that was a hot item last year.
anyway I dont really know much about computers, just talking about what i have and my experience with it.
