You're not giving us enough detail. lol
Budget? How much are you willing to use?
Do you only need the tower? Or do you also need things like monitor,keyboard,mouse,OS?
Are you planning to only game? Are you also planning to OC?
FX 8350 CPU
GA UD3 MOBO
120gb OCZ vector SSD
R9 270x 4GB edtion (comes with battlefield 4)
8GB Kingston HyperX 1600MHZ DDR3
500watt PSU Corsiar/ThermalTake
Razer peripherals(best for gaming in my opinion/steelseries is ok too)
If you need a monitor go for a cheaper one in the 23" range, the Acer 23in is what I'm using it's perfect, if you got a little extra money go Asus; mainly because "they run this shit" as far as monitors go. If not just use an HDTV with an HDMI cable.
if you want to OC throw in a Evo Hyper 212 for the CPU, the card should have sufficient cooling to do a little OCing as is...
