[quote name='Vanillanowah']I did have another question though, my current PC isn't really a monster or anything but it's good and has been able to run a lot of other stuff (I have an AMD Athlon II X2 215 Processor w/ 3.8 GB usable RAM, and an ATI Radeon HD 4250 video card). Would it be much cheaper to just buy certain components and upgrade the PC I have now? If so, what upgrades do you recommend? Thanks a ton![/QUOTE]
First it's important to know whether it's a prebuilt computer or not. If it is, say a Dell or something, then it's probably not feasible to upgrade. Prebuilt computer usually have awful cases and power supplies that will either not be large enough to fit newer, larger equipment (good GPUs take up hella space) or have shitty airflow and cooling (good CPUs/GPUs give off hella heat.) Or they're just awful to work in.
From some basic, quick Googling it looks like your processor is coming up to three years old, and was the slowest of the line. That means it's going to be the bottleneck if you replaced your other parts. If you want the latest games at 1080p/30FPS minimum, you'll need something with more juice.
The amount of RAM is ok, but the speed and type are more important. It should be DDR3, ideally 1333 or above. Lastly, your graphics card. This is baffling me, as I see results implying it's a mobile chipset. It could also be an integrated desktop graphics card, meaning it's the motherboard's built-in card. Either way, you'll need something new and modern.
With all of that out of the way, I'd suggest giving a looksie to
this thread on NeoGAF. The OP has some good build suggestions. Start there, and keep reading. Take a few weeks to research the parts, see how they'll suit your needs, and go from there.
