Wondering about a good GPU for WoW WoD

[Malicious Tank]

hey guys, long time reader first time poster here.

I've just purchased a new computer and I think the specs are pretty good but I know I need a graphics card so that I can fully play World of Warcraft on Ultra Settings, keep in mind this is the ONLY game that I play on my computer so that's all I'm looking to optimize my computer for. Any feedback on a good graphics card or anything else you think I should upgrade would be helpful thanks in advance:

Going to move this to the Build/Upgrade subforum!

In the meantime... You shouldn't need anything greater than a 760... So a 750ti or 660 ought to suffice. Unfortunately, your CPU will chug a little on Ultra in 20/25m raids, and there isn't much you can do about that since you already bought it (Consulting people ahead of time is a must!).

Do you know what PSU it has, or a link to the system itself?

I'm sorry I fail you're right I should've asked first but I guess I got stupid. Here's where I purchased the computer with the exact spec:

I'm planning on purchasing the GPU:

Now I just need to know if I need to get a new PSU so I don't kill my computer

Thanks again for any help/feedback

That PC has 300W PSU and probably crappy one. So no, you will need a new PSU.
http://pcpartpicker.com/part/xfx-pow...ply-p1550sxxb9 is what I would recommend.

Also for exact same price, non reference 760
