well you can buy a good gaming video card for about that much, but a whole system is not going to be good for gaming at that price. unless you dont mind playing older/less demanding games

that is about the best your going to do for $300. that is bare bones no OS, no keyboard or mouse, basic power supply. It will run most of the latest games in low-medium detail settings, demanding games like bf4 or crysis 3 it will struggle even on the lowest settings.
you could put a better i3 cpu and 2g 7790 gpu bring it up nearer to $400 http://pcpartpicker.com/p/2rUKm and you would have a reasonable gaming computer. if you raised it to $420 you could get a 2gb 650ti boost which would be a fair bit better, good enough for 1080p gaming at medium-high detail.

For $300, you can go for this:

CPU: AMD Athlon II X4 750K 3.4GHz Quad-Core Processor ($80.98 @ Newegg)
Motherboard: MSI FM2-A75MA-E35 Micro ATX FM2 Motherboard ($59.99 @ Newegg)
Memory: A-Data XPG Gaming Series 4GB (1 x 4GB) DDR3-1600 Memory ($29.99 @ Newegg)
Video Card: Sapphire Radeon HD 7770 GHz Edition 1GB Video Card ($84.99 @ Newegg)

It's a bit over, but I didn't skimp on any of the parts.
The case and psu are both high quality and will last you a long time, but remember that if you plan to upgrade the gpu in the future, 430w may not be enough.
The 7770 is the best card in its price range.

For the $400 budget:

I took the $300 build and upgraded the gpu and processor. The FX-6300 is much stronger than the 750k and since it uses a different socket, you needed a different motherboard. The Pro3 is a decent motherboard but you can't beat it for the price. It enables you to be able to overclock the FX-6300 later on.
The 7790 is a step-up from the 7770. Not a huge performance increase, but it's still a step up.

4gb ram is not enough to get a smooth experience on many games. you need to take it up to 8gb and shave the cost off somewhere else.

4gb should be fine as most games only use 4-6gb of ram. There's really no where to shave off the price other than the cpu/gpu. And then again, the OP will get better performance with a stronger cpu/gpu and 4gb of ram over weaker cpu/gpu and 8gb of ram.
RAM can easily be upgraded in the future by just buying another stick and plugging it in, while with the cpu/gpu it's much harder as you have to replace it.
At this budget, 8gb isn't really worth it. OP should already know that he won't get a great gaming experience at this budget.
