So i recently purchased my pc parts and realized after two sticks of 4gb ram is faster than 1 stick of 8GB ram. Is it a big difference in performance? The ram is 8GB of Crucial Ballistix Tactical 240-Pin DDR3 RAM.

At most it is a small performance gain with dual channels.

Yes its worse, no it's not huge somewhere in the 10~15% range seems to be about par. Most comptuers aren't memory limited however, so this usually doesn't make a 10~15% performance difference overall.

Agree, you will see a performance boost in memory throughput using two modules instead of one. If the part can't be returned, funding allows, and you want the performance boost, matching the stick precisely with a second one will likely do the trick, although it's recommended to purchase matching pairs in a kit, as the memory is guaranteed from the manufacturer to work at that point.

single channel usage of ram is 15% slower yes. but it will still be operational and when u can afford another 1x8gig stick ull have 16 gigs of sweet ram.

The loss is minimal. The RAM will run just as fast, all that's happened is you've cut bandwidth in half by using only 1 stick. That Tactical is some really good RAM. If your performance loss bothers you, get another 8GB stick of that :)  Costs about the same as getting a 2x4GB kit anyway. Having 16GB is a nice little bit of future-proofing, plus you can carry it over into your next build since it'll be awhile yet before DDR4 becomes mainstream.

Thanks, so for example will BF4 run well on it with one stick of ram? My GPU is an Giagbyte R9 270X Windforce edition and my CPU is an AMD FX 6300?

yes it will run fine till u put in another 8 gigs sir.

yep will work good with those parts.

Playing games is the most likely way to make your performance loss apparent. Games tend to use as much memory bandwidth as they can get when CPU bound, as I understand BF4 to be, but as your graphics card looks like it matches fairly well, I wouldn't expect more than perhaps a 5 - 8 FPS difference between single and dual channel.
