Upgrading Season.. Need Some Advice.

[Shandodo]

With the Chirstmas Rush I tend to try to find a good upgrade for my Rig and my Fiances Rig.

Here is some information about mine

Budget - Around 200-300$
Resolution - 1920x1080 (Eventually want a 3rd Monitor)
Games / Settings Desired - WoW at High+
Any other intensive software or special things you do (Frequent video encoding, 3D modeling, etc) Just some Video Rendering for Youtube.
Country - USA
Parts that can be reused - Whole Rig. Mianly looking to swap the GPU I think.
Do you need an OS? Nope.
Do you need peripherals (e.g. monitor, mouse, keyboard, speakers, etc)? Nope.

My current specs are as follows

CPU - Intel Core i7 4820K @ 3.70GHz Ivy-Bridge
Mobo - SABERTOOTH X79
GPU - NVIDIA GeForce GTX 760 (EVGA 4Gb)
RAM - 32.0GB Dual-Channel DDR3 (1666)
OS - Windows 10 64bit
HDD - WD 2TB Calviar black
SDD - 250gb Intel (530? i think)
Monitors - I currently have two 22" I eventually want a 3rd.

I'm looking for some advice as to if I should get a new GPU - Hold out - Or buy a 2nd of the same and SLI them. Cheers in Advance. I'll post some more in formation from my Fiances Rig once I set her back up on Win 10.

You don't really need an upgrade except maybe gpu. What games are you playing? If you are satisfied with the fps you are getting then obviously you don't need to upgrade. You can grab a gtx970 for 300-330$ now or wait for next gen coming out next year, we don't know when exactly. But if i had to guess you would need more than 300$ so...
