I would recommend the following, add an HDD for storage later on. Now this might be more than you can spend? If so you can change the GPU to this Asus 7770 99Ls and maybe a cheaper case as well like this Gigabyte model 26Ls

CPU: Intel Core i3 3240 (87Ls)
Motherboard: Asrock B75 (35Ls)
Memory: Kingston HyperX 8GB (2 x 4GB) DDR3-1600 Memory (37Ls)
Storage: Crucial M4 128GB SSD (72Ls)
Video Card: Sapphire Radeon 7850 2GB (121Ls)
Case: Cooler Master HAF-912 Combat, USB 3.0 (49Ls)
Power Supply: Enermax TRIATHLOR 550 W 80PLUS BRONZE (56)
Optical Drive: SAMSUNG SH-118AB/BEBE DVD Writer (16)

Total: 473Ls
