Massive post is massive.
thanks for all the feedback guys. I'm just wondering, would I be better off altogether building a new comp or just upgrading the one I have?
Last time I checked, only i3's had 2 cores, and i5's had 4 cores? I might be wrong, but I JUST built a PC out of an i5, and everything I looked at had those specs.
But anyway, MOST of the time, it is more worth it to upgrade IF you have a good enough motherboard to handle what you plan to drop in. One question you have to ask yourself is if you are comfortable with working on a computer (upgrading, building one, etc.)? Do you know about the danger of ESD, and how to avoid it? Do you know how to safely handle hardware? When you do upgrade, try to look at the total power draw of what you plan to use. You can use this simple calculator
HERE or this more complex one
HERE to try and figure that out. Generally, one current gen GPU will get you by one most games (not always on MAX, of course). But some of it also comes down to the CPU. If your CPU is a dual core, that might not cut it. You could always upgrade it down the road (The LGA 1155 socket is newer, what you have is 1156 I think). To upgrade the CPU, you might need to buy a new motherboard. You could use this to your advantage and futureproof your PC by going with either an 1155 socket, or go AMD (their 8-Core Bulldozer CPU is actually CHEAPER than a i5-2500k.) Take all this into consideration when planning. Another alternative to that is overclocking, although this requires above average cooling (which is expensive, depending on how good you want it to be. Coolermaster makes a pretty good CPU cooler called the Hyper212+, which is only about $20). You can read more about overclocking
HERE if you want to check into it. You might not be up for the risk, though. To each his own. My CPU is currently running at 4.5GHz because of overclocking, though. :awesomeface:
In addition to this, DO NOT, and I repeat, DO NOT EVER skimp out on the PSU. It is, in essence, the life of the PC in the balance there. If you buy a bad (low cost) PSU, it might die and fry your PC, killing it instantly. Yes, good PSU's are expensive, but there is a reason for that. An overvolt or PSU failure would blow your entire investment. If you can afford it, go for SeaSonic (their PSU's are pretty amazing), Corsair (known to be pretty reliable), or Coolermaster (not sure if they have as good ratings, check the before buying of course). Make sure you are comfortable with the PSU's failure rates before you run out and buy one. When you look at video cards, you might not understand what some of the information means, or something similar. I could explain it to you, if you want to, but you could probably find something on the internet a lot faster. There are also a lot of price categories that tend to show a lot about the video card. Some stuff on the various price categories that have a LOT to do with performance,
HERE.
I'm not trying to scare you here, just make sure you understand the risks and consequences before you do all of this, since you bought your last computer from a manufacturer (most likely, seems like you have OEM parts). And if you know all of this already, sorry for telling you again and making you read all of this... Haha.
And here are a few video card recommendations (some AMD, some nvidia; these are mid-range cards that would handle the games you mentioned pretty well, for the most part):

And here's a good series on how to build a computer if you want to, and haven't done it before (by newegg, but no, I'm not a fanboy of them. lol):

And again, sorry about the massive post, it did get kind of long, but there is a lot about computers you need to know. :|
