Intel Core i3 2nd Generation 2130 (3.4GHz)
LGA1155 Intel Chipset Motherboard (NEW B3 Stepping)
8GB DDR3 RAM
The i3 is dual-core, you'll probably want to move up to quad. I recommend an i5 2400
or add $15 and get a 2500 - your choice. The K-version is not necessary for your needs.
Most of the ASUS/Gigabyte 1155 motherboards are crap, so a reliable motherboard for the 1155 socket is the AsRock Extreme3 Gen3
, or spend $40 extra for Extreme4 Gen3 if you want USB3 ports.
For RAM, get a model that's on the compatibility list for the motherboard:
Personally I'd recommend G.Skill or if not possible, Corsair.
I'm sure a GTX560 card can run BF3 at the resolution you desire, since my 570 can run it at 1920x1200 on Full (with 2xAA) at a billion FPS.last edited by parabol at 16:28:26 19/Mar/12
