So I have a relatively mid-priced PC for gaming, and recently, I borrowed my friend's reference 980 Ti until the new GTX 1080 comes out later this month. However, now that I've gotten around to installing it, I noticed I've been getting less than 50 FPS on beefy games like GTAV and R6S running mostly at Max setting on 1080p. My same friend has a second 980 Ti (he was SLIing), and he gets close to 90 in GTAV, so what the heck?

While playing I noticed my 8GB of DDR3 RAM was at 90-95% usage, and while playing BF4 (but not GTA) my cpu was at 90% usage. So is getting 16 GB RAM a quick fix, or is it time to upgrade to a new CPU? ( Like an FX-9590 or i5 6600k?)

System specs are as follows:
-AMD FX-8320 eight-core CPU
-GeForce GTX 980 Ti
-ASUS M5A78L/M USB3 MoBo
-2 x 4GB Kingston HyperX Fury DDR3 RAM
-Seagate ST1000DX001 1TB SSHD
-PNY CS1311 240 GB SSD
-EVGA Supernova G2 850W Gold PSU

Lastly, I run a bunch of apps in the backgroud like skype, adobe, uplay, spotify, etc.

FX-9590 isn't an upgrade, it's a nightmare of epic proportions made in hell. Literally, due to the heat and TDP. Do not do that whatever else you do. Certainly and for sure not on that board. In fact, that motherboard, while perfectly fine for an FX6 chip, isn't even suitable for your 8320 to be frank.

Tier One: Fine quality. Good boards with fine enough thermals and power phases to contain FX 6, even OC it. Quality is decent for the price. Do NOT pair FX 8 with them, they may take the load of FX 8, but Power phases will not be good enough. No Crossfire/ SLI capability.

NOTE: M5A78L-M/USB3 does NOT have heatsinks on VRMs so don’t expect high OC on this board. It’s quite fine for stock speeds...

What are your CPU temps looking like when your frame rates are dipping? It's entirely possible that you are being throttled/thermally limited.

Honestly, it's doubtful that FX-8320 is going to do well trying to keep up with that 980 TI on seriously demanding, primarily single core usage games.

The FX line of chips is going on four years old, and even Sandy and Ivy bridge Intel chips from years back generally outperform them in single threaded games and applications. If you are planning to get a 1080 I'd definitely seriously consider that it's probably time for a change to an Intel platform of some kind. Either something from the X99 or Skylake families would be a good idea, but even a Haswell refresh configuration would be miles better than that 8320. I just recently ditched MY 8320 and went with a 6700k and Gigabyte Z170-Gaming 5, and the difference is appreciable.

If you went with Haswell refresh you could still use your current RAM, depending on what speed it is. If it's 1600mhz or faster it would be fine with HR. Considering you can get 8GB of DDR4 for about 35 bucks and 16GB of it for about 56 bucks, it would seem to make a lot more sense to simply move to Skylake, Haswell-E or Broadwell-E though.
