Please go play Uncharted 3. Apparently I am in completely over my head here, but you build me a $250 (Price of a PS3) computer that can play Uncharted 3 I will call myself an idiot for that statment.
Unfortunately there is no way to play Uncharted 3 on the PC.. but if I had to guess, it could be pulled off extremely well if you bought the proper items:
Radeon HD 4870 - $59.99
AMD Athlon II X2 250 - $68.89
G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-4GBRL - $30
We are at... $140?
Get a $50 MB and a $25 Power Supply.. and we are looking at under $250.
