How should I upgrade my PC?

[Solomore]

250$ coming in, and I want to upgrade my computer, heres my current setup

In september I ordered this PC from iBuyPower, which is great, however since Im using a 1280x1024 monitor im thinking that due to the ram usage or my video card things will get laggy (Ill be getting a 1920x1080 monitor). I currently run on Max settings with around 20-40 fps, but I also plan on buying games like BF4 and other games.

Sorry to say this, but you got scammed :/
Anyway, if you want to upgrade this, you need a whole more than 250$ (canadian right?)
If you can spend a bit more, the best upgrade would be a new GPU GTX 760 http://ca.pcpartpicker.com/part/giga...n760oc2gdrev20
But I am not sure that PSU is gonna cut it >.>

So you can get a bit weaker 750TI and new PSU

Yeah that gpu is pure shit, go for 7970 or the 760 mentioned above. The psu is well enough, you can run a titan off that wattage wise.
