I'm completely new to this, but this is what I came up with with my roommate:

I don't need peripherals, OS, or storage. My goal is to be as close to $500 as possible.

Here's the recommended build I received in another thread:

When talking to my roommate he said that I really was going to want to get a discrete GPU so that's what I tried to go for. I was able to save the $73 since I already have hard drives. What do you think? I went for that power supply because there is a great deal on Newegg at the moment. I'm sure that the Antec would be fine since the estimated wattage is only 279. Is it bad to get the 700W if I don't need that much? Any and all feedback is appreciated!

Drop the cpu to a Athlon x4 750k and get a cheaper motherboard and also drop he aftermarket cooler. Then use the money you saved on a gtx760 instead

Is the 760 way better than the 650? I'm looking at this one since it's the second most inexpensive:

Does the "DVI-I Dual-Link 2" mean that I could set-up dual monitors when I couldn't with the other? If so that's definitely a perk. I see on Newegg that the memory clocks at a higher rate and has double interface size, but I'm not sure exactly what that means haha. My goal is to play FF 14 (specs:http://lodestone.finalfantasyxiv.com/pl/envi/envi01.html), League of Legends, and Wildstar (specs:http://wildstar.gamepedia.com/System_Requirements) on high settings. Thoughts?

Thanks for the response by the way!

Also, what is SLI Support?

Also would you say that this card is a good option?

I think within my budget I could upgrade to it without having to ditch the cooler or downgrade my motherboard/cpu.
