Lost my old account info so starting over:/. I work a lot and have limited free time, but have been playing Battlefield 4/ Star Wars Battlefront beta when I can lately. Both run very well and smooth, specs on my PC will follow. The most recently released specs for battlefront make me think I may need to get away from PC gaming (due to cost/time) OR get more RAM. Obviously, a RAM upgrade is more cost efficient than a console. I would appreciate your feedback, I will admit I am kinda out of the loop lately!
 
EVGA x58 Classified 3
Intel i7 930 @ 4.2ghz
6gb (3x2) Corsair Dominator DDR3 @ 1600
Intel 240gig SSD (newer model, g2g)
EVGA 970 SC (used to have 2x GTX480's)

Your pc still looks capable and you're right, some more RAM is not too much (I thought an i7 930 @ 4.2Ghz was faster than a stock 2500K for gaming anyway?) . What resolution do you game at because if it's 1080p or so you should be fine.

You could always get a console and buy a XIM4. I have one and it makes console gaming pretty comparable to PC gaming. Not to mention being used to playing as master race against the plebs is super easy. 

I have a XIM3 for the 360 and love it! I wouldn't go around announcing that you use one though.. controller nubs get mad.
I purchased a used Xbox One last week for $150, picking up a Kinect today for $60 and received the TV Tuner yesterday for $60. For me, using it as a set top box is what I was interested in. With Windows 10 and SmartGlass, I can stream to my PC or mobile device and not interrupt my wife. My 360 takes forever to load apps and I'm hoping that the Xbox One will be a breath of fresh air (I haven't had time to tare down my entertainment center, dust and re-wire).
My PC specs are in my sig (I think), and I don't plan on upgrading my P55 for a while. If I do, I would probably buy a Surface Book or Surface Pro instead. Heck, even the standard surface wouldn't be bad if I streamed from my main PC.
I spend little time actually at my PC lately.

Thanks for the feedback all. I am playing at 1080p and I will not be upgrading my monitor. I do prefer PC gaming and am wondering if this is the last upgrade before being completely out of date.

Also looking at my local microcenter's Crucial Ballistix memory (in stock) for convenience, but I have no experience with this brand and not sure how good they are.

What is your opinion on the CCrucial Ballistix memory? If that is alright I may run to the store and get it today.

I like Crucial memory and had some in my last rig. As for upgrading the main components, the i5-2500k is slightly faster vs the i7-930 but it's also easier to overclock and uses less juice. Keep in mind that it's also a bit old now and the new ones are a bit faster and more efficient.

Thanks for the feedback again everyone. I did pick up that Crucial Ballistix RAM, computer didn't blow up so I think I am all good. Bios settings change was easy and all of it shows up. Funny thing was I was running a couple rounds of battlefield 4 and my system memory use was at 5.9 gigs (has 6).....evidently I was riding the razor's edge for a while.
