I was thinking of upgrading my system AGAIN, but here is my specs now.
PSU: Corsair VX 550W PSU (ATX 12V V2.2, 1x 6pin, 1x 6+2-pin PCIe, 6x SATA, 120mm Fan)
CPU: Intel Core 2 Q9400
Screencard: MSI GeForce GTX 470
HDD: Cant remember.
RAM: 4x2gb ram.
if i buy a new CPU (Intel Core i7-950) and a motherboard (ASUS P6X58D-E), do i have to upgrade my PSU for more 'wattage'?
