Hey! I know this has been asked before but I wanna make sure that my build is capable of optimal performance if I decide to buy another graphics card.

My current build looks like this:

Corsair Carbide Air 540
Sabertooth 990FX R2.0
AMD Vishera FX-8350
Coolermaster Seidon 120V Watercooling
Cruical Ballstix Sport DDR3 1600mhz 2x 4GB
Asus GTX 760 OC DirectCU II
Samsung 840 EVO 120GB SSD
WD Red 2 TB NAS Hard Drive: SATA III, 64 MB Cache
Corsair TX650W PSU

My build performs really well as it is, but I would like to add another asus graphics card to my build. There is 2x PCI-E connectors from my PSU.

I have used the eXtreme power supply calculator and it told me the minimum psu wattage for this build is 500w. (Including fans etc)

Is this accurate?

Your best regards, cha00s.

Oh, and also I wonder if I would notice any increase in performance if I would add another 8GB of RAM to my build!
