11. Mouse: Corsair Vengeance M65 FPS Gaming Mouse

Soon to buy list:

2. GPU: Don't know yet
3. Games: I am very interested in Far Cry3, Crysis 3, Hitman: Absolution, Batman: Arkam Origins, Watchdogs, Battlefiled 4, Tomb Raider, Metro: The Last Light....For now.

I will really like if anyone can give me some opinions of choosing the right GPU for my needs and it can run with my system above. Just to be cleared, I am very interested in the Asus geforce GTX 770 2Gb, but I am worried if my power supply is just to low and I am looking forward to overclock my CPU. Can anyone give me their Opinion? What will you do if these is your Build? Help me choose the right GPU.
Thanks!

I don't have a lot of knowledge regarding overclocking, but if I was thinking to overclock it up to 4.0GHz.[/quotemsg]

That should be fine, without the OC your system should use around 570-600W.

I love those cards! I will like to have them but, my question to you is....If I overclock my cpu with any of the cards you suggested...Do you think my power supply is enough to handle my system?

That was the card that I wanted but, AMD is recommending a at least a 750 power supply which I don't have.

To be honest I'm not sure exactly how much more power that would require... If it is a small OC (like 300mhz) then you probably would not even need to change the voltage, so it kinda depends on how much of an OC you want. But the PSU should still be okay.

That must be a typo, my 7970 only required a 550w psu (AMD recommended). The 280x is just a newer 7970 that's more energy efficient.

This is what I use to figure out my power requirements when I'm assembling a pc. It's not exact, but it's an excellent guideline to work with.
