Yeah, I'd like to make it into a gaming PC too . Uhm, do you know a way to make it process up to about a stable 150 fps or so? I play this game League of Legends and I was wondering if I could get it up to 150 FPS while on high quality settings. Will the build you gave to Marisolvii work for me ? I have a budget around $450-ish too. Can you give me some specs that would run something as nice as Anklespankin's gameplay? (He's a youtuber that plays League of Legends at high quality settings and gets about 100-200 FPS. 120-ish stable) I have 8 GB of RAM right now and I'm wondering if I can upgrade that too and get about a quadcore processor that won't break my PC or something.. thanks!

Once again, I repeat my spiel.
Having more than 60fps is useless, unless you have a really expensive monitor. Most monitors can't go any faster than 60fps. Trust me. 60fps is the target. Nobody needs 100fps. The Youtuber might be able to use 100-200fps because then he can achieve slow-motion effects. But also he probably has an expensive $1500-$2000 build that is capable of running most AAA games well at high graphics quality anyway. I'm assuming you don't know the price points for good computers: Anything below $500 is generally crap, $500 is "mainstream" or "low-end" in my esteem; a decent mid-range computer will cost around $900-1000, and a "high-end gaming PC" will typically cost at least $1250. This is if the computer is custom-built from scratch, by the way - some companies will screw you over and you might have to pay $1700 for what I'd call "high-end".
League of Legends is an easy game to run. I don't know how easy because I've never played it. But we should be able to get you 30 to 60 fps at high quality because it's just a 2D MOBA; from what I know, desktop MOBAs are easy to run because they don't involve as much detail in gameplay, and the graphics are often less detailed and more cartooney compared to most AAA titles that try to be somewhat realistic.
A quad-core processor is pretty reasonable - but most processors worth buying these days manage what any quad-core manages. Even cheap Intel Core i3 processors, which are physically dual-cores, have the same number of processing threads as quad-cores. Basically it can process the same amount of stuff as quad-cores, even though it's a dual-core. This is thanks to a technology called hyper-threading, and most processors perform like quad-cores since they usually have hyper-threading. Of course, you should check with the manufacturer's specifications to make sure the dual-core processor actually is hyper-threaded. Don't worry, though, we can still get you a cheap quad-core.
8GB RAM is pretty good, actually. You can never have too much RAM, but if you have more RAM than you need, getting more RAM is useless. Few games use more than 6GB RAM, and combining that with what Windows uses, usually about 1GB, you still have some RAM leftover. Someday, maybe you can upgrade to 16GB, but not with a $450 budget.
For $450 I'd recommend basically the same build as I did for Marisolvii:
Athlon X4 860K processor for $80. It's a quad-core, it's cheap, but it's got great bang-for-buck.
ASRock motherboard with A88X chipset for $57. Works with the gpu we will use, small enough to fit in your case, also easy on the wallet.
500-watt EVGA power supply for $50. Provides enough safe power for the whole system. Hopefully your case will allow for the installation of a third-party PSU, sometimes they use proprietary stuff.
...
The graphics card is where things change. Since you have a bit more money than Marisolvii, we can get you a nicer GPU that costs more, but performs better, has a smaller size and thus will fit more easily in your relatively small case, and uses less power. I don't know how much space is in your case, you'll have to measure it yourself by opening it up.
Here's the choices...
Gigabyte GTX 960 Mini Edition, at 7.125 inches long, costs $200. It has the fastest clock speed, but it's also the longest card and is least likely to fit.
EVGA GTX 960 Superclocked, at 6.8 inches long, costs $200. It is faster than the Asus, but shorter than the Gigabyte.
ASUS GTX 960 Mini, at 6.7 inches long, costs $215. It is the slowest and most expensive out of the bunch, but it's also the smallest.
I'd recommend the Gigabyte card if you can fit it in your case. Otherwise, the EVGA card is your best alternative since it's cheaper than the Asus card.
So this will help you run the game really well at high quality.
