Seriously now.. According to reports, the PS4 will be capable of delivering 1.8teraflops. The 7790 delivers 1.79tflops, the OC version more. Your computer though will be slightly faster due to the 3570k and presumably faster memory clocks and faster busses of the B75 chipset. Efficiency-wise, the PS4 might be more frugal.
A console might be very enticing. There are more games available to the platform but in the end, kung mapul-an ka sa console mobalik ra gihapon ka once in a while sa PC. This is my opinion and kung akoy papilion, dili na lang nako ibaligya ako PC. Tigom na lang ko pamalit ug PS4. You can have both but you cant have just one of them..
Add: Pwede pud baligya nimo ang PC then decide na lang later kung kinahanglan pa nimo ug PC or Laptop
