This is to shut up GW16's argument that a PC costs more than a console. It's all faulse and here is the proof.

I will make a PC that will perform like a Xbox 360 and will cost around 350$.

CPU: I chose the AMD 2,8Ghz because it has 2mb of cache and not 1mb like the Xbox's 3.2Ghz triple core. The cache makes the 2.8 equal to the 3.2 knowing that having more cores makes no difference in game performance.

82$

Mobo: No special reason.

60$

RAM: Knowing that Xbox has 512mb you can pick this instead but it'll suck on Vista AND XP.

41$ or 12$

GPU: Knowing that this is about as powerful as the Xbox.

67$ or 48$

Now we're at exactly 250$ and this stuff is much better than a Xbox 360.

Case and PSU: A 400W stock isn't so bad I had one and sucked much more juice, if you want more.

25$ or 25$+25$

CD/DVD Writer: no special reason.

21$

HD: On PC you need a 250GB.

45$

Total: 340$
