Hi guys, just a quick question, I want to buy Dead Space for the PC but my problem is that my PC has a 2.1ghz AMD Turion 64 x2, Dead space requires a single Pentium 4 processor (2.8ghz) so will this game work on my PC????

Should note that I have a 256MB GeForce 8400M GS graphics card, Dead Space requires 64MB...
