Can my PC handle it?

[Oneyejoe]

So as of now i have my first PC build, that i finished a few months back, as of then i was on a tight budget, and here are my current specs...
PCU - AMD FX 4300 3.80 GHz (Quad Core)
GPU - XFX Radeon HD 6670 2GB GDDR3
RAM - 8GB
PSU - http://www.ebay.com/itm/600-Watt-600W-ATX-Power-Supply-SATA-Dual-80mm-fans-Silent-for-Intel-AMD-PC-Unit-/271198844722?pt=PCA_UPS&hash=item3f24b5f732
Case - The Rosewill Challenger
Motherboard - http://www.newegg.com/Product/Product.aspx?Item=N82E16813131795&cm_re=Asus_micro_motherboard_AM3%2b-_-13-131-795-_-Product
And a 1TB hard drive.


NOW onto my question. i built this for gaming and i can run most of my current games decently, but as i play i notice more and more how sluggish the FPS is due to my cheap little GPU. SO ive gathered up a bit of money ($325) to spend on a new GPU so i can run games way faster and smoother, (like Farcry 3, Crysis 2 Maximum edition, Racing games like DIRT, and Splinter cell Blacklist, The Forest, Payday 2) ya know.. the fun good looking games (even the old stuff runs a tad slow with my current one, so i was wondering if i were to buy a GPU around 250 or 300 dollars would my PC perform much better as im hoping? or will i Bottleneck? which is a term i just came across, (im a PC convert from consoles haha) so ya i just dont want to waste my money and be disappointed. Any suggestions as far as a GPU goes? and will i need to upgrade other components to be able to enhance my gaming experience?

if you buy a gpu then obviously you will get good fps in games just oc your current cpu to avoid bottlenecking i wil recommend you to get a r9 270x and an aftermarket cooler for overclocking under your given budget..

So my CPU is the only thing that would cause bottlenecking in my case? and also i do not know how to OC, and as ive looked up how to in the past it seems very tedious, and easy to screw up and fry your parts.

Also i forgot to mention my screens resolution is 1600x1200 if that has anything to do with GPUs

If you're upgrading to a much higher-powered GPU, you need to replace the junk power supply.

Even if that were a well-made PSU (it's not), it's not going to power much, with only 22A on the 12V rail (by comparison, the XFX 550, a well-made PSU for modern PCs, has 45A there).

I was thinking the same thing but i wanted to make sure. and hear opinions/facts from other people

It's definitely brutal. Even if it were well made, 12v is pretty much all that matters these days. Only the lower-power parts, like the hard drive or the optical drive or any sound cards have any interest in the +3.3V or +5V rails and those use almost nothing when calculating the power you need for your system. That 600W, even if it was made with quality components is more or less a 250W power supply when it comes to modern PCs, the CPU and the GPU wanting juice off the 12v rail. If I'm not mistaken, the last CPU that wanted a beefy +5V rail was the Pentium IIIs that came out in the late 90s.
