Help with upgrade.

[Orf]

Hello,
I wanted to know if its worth to upgrade my current rig, its about 3 years old, so wondered is it worth to spend some money or just use for it for like 1 year and buy new one. Im not very big gamer playing just wow, GW2 nothing very fancy, but want smooth gameplay. This is my curerrent rig:

Cooler Master Elite 120 Advance, Mini ITX
MB H87 S1150 MITX/H87I-PLUS ASUS
CPU cooler Scythe Kozuti s. 775/1155/1156/1366/AM2/AM2+/AM3
DDR3 Crucial Ballistix Sport 8GB 1600MHz CL9 1.5V
PSU Corsair CX 430W, 80 Plus Bronze, 120mm
WD Black 3.5'' 1TB SATA3 7200RPM 64MB
SSD Crucial M500 120GB
Intel Core i5-4670S, Quad Core, 3.10GHz, 6MB
ZOTAC GeForce GTX 750 Ti, 2GB DDR5 (128 Bit)

I have very good offer for used Gigabyte GTX970 mini ITX overclocked 4gb, its prety hard to find what could fit to current compact pc case, but wondering if it worth to spend money for this rig. Besides does current PSU have enough power for gtx970? Usually i playing playing just wow at 1280x1024 resolution, but probably ill buy new monitor, i want something bigger than 19" so my old vide old card probably will have fps problems with higher resolutions. Guys what you could advise me: to buy gtx 970 or wait some more dont spend money for this pc and buy new rig or may be upgrade something else? Beforehand thanks for your help.

The only upgrade that would be worth the money in your case would be a GTX 1060 graphics card and you would probably need a new PSU for the GTX 970 if you intend to buy it.

My recommendation to you is to wait for the next generation of nVidia cards and don't buy a new monitor until you have a better graphics card... I recommend BenQ.
