Spending Very LITTLE to get what you want.
I built a PC for under $500.00 that runs this game at 45fps-50fps @ 720p and scores a 4100 or higher if I remember correctly on the Benchmark when running AMD Dual Graphics with the CPU's built-in GPU hooked up to an LG 37" LCD TV.
AMD-A8 @ 4.6GHz w/ Dual Cards 7750
ATI Radeon 6570 w/ 2GB Core Edition
F2A55-M Motherboard
8GB (2x4gb) PNY Memory
Anyways, with the DVD Drive, it came out to 476$. Now I could run the game at 1080p but then I notice a a slightly graphical stutter and I dislike that and I'm not a videophile so I don't need 1080p to enjoy a game as I used to be a PS3 player and running it on the PC now is 100x better.
