Need major upgrade help

[Bigolcrittys]

Hello,

My friend got a new computer and gave me his old one. I'm able to spend around $200 or so a month over the next couple months on upgrades. I'd prefer to keep the total upgrades under $1,000 but willing to spend more if necessary. I'm willing to save some to buy better stuff as well. I'm looking to play WoW and similar games on High (and eventually Ultra) settings at 1080p. Basically what needs to be upgraded, and what is the most important to upgrade first. Here's the build:

You'll need to specify whether or not you're limiting yourself to sub $200 purchases at a time or if you're able to save and then spend more than $200 at a time.

That said, you're not going to get any meaningful upgrades at under $200 a shot. Processor and mobo would be out of the question, and you'd be restricted to all but the lowest tier video cards.

I mentioned in my post that I would be willing to save to buy better stuff. I'm also not spending over $200 on a mobo

It's not that a Mobo would cost $200, but that if you got a new one you would also need a new CPU.

Honestly, the system above is still plenty solid for gaming with just a GPU upgrade.
