Still, the 650W and 750W are the same prices on neweg.

Oh, I forgot about AM3 being forwards compatible with AM3+.

If your motherboard supports AM3+, then definitely get the 8350. It's not worth it to buy a completely new motherboard for maybe a little more performance in TF2 (and less for multicore processes).

While it's true that I do stream at 60 FPS and OBS handles it quite well, a few days ago I ran that TF2 benchmark when I wasn't streaming. At stock speeds with Chris' dx9frames, this was my result:

2639 frames 30.184 seconds 87.43 fps (11.44 ms/f) 3.084 fps variability

This is with ragdolls on, and my FX-8350 running at stock speeds (4.0GHz). With them off, my FPS rises up to about ~95-100.

Whereas someone a few posts about me with a i5 3570K at 3.4 GHz (also stock), was able to average ~115 fps with the same config, dx9frames.

2639 frames 23.469 seconds 112.45 fps ( 8.89 ms/f) 4.687 fps variability

In order for my own FX-8350 to reach those speeds, I had to overclock it at 4.8GHz; and I haven't yet been able to overclock my PC successfully so that's not even really an option. (Partially because I'm new to the OCing business and am worried of killing my PC)

If it's possible I'm missing some key component to making my game run smoother, it'd be super nifty if someone could tell me. :o

It really depends on how much you want to play modern games and how important it is to you. I would say that a 7850 is a good enough graphics card and it's cheap too. It can run pretty much anything, maybe with a couple of exceptions of not going on absolute max but if you can deal with not turning on AA and AF then it will probably run everything on max for at least another couple of years. In terms of tf2, it won't help at all. But anyway, I'm saying that because I don't play other games THAT much and tf2 is way more important to me, choose based on yourself

About the 8350, it's a completely valid option but what ruins it for me is that although average fps can be similar, amd is less stable and it seems that min fps goes lower on amd. I'd just go with intel to be completely safe, especially for games that aren't tf2

Although the i5-3570k technically beats the 8350 in just pure gaming when playing TF2, it still doesn't change the fact that the 8350 handles streaming much better.

I'd like to see some evidence that supports your reason.

I just got around to looking inside my case and I have 700W.

In terms of RAM, speed is usually not your problem. 1600 in this case is the speed of the RAM. 1600 is pretty much 'normal' speed for RAM. I have 16 gigs, no real difference from the 4 I had before. But I do no video editing, and that's the main use for large amounts of RAM in a desktop. I've played with Vegas render times when I allow it to use varying amounts of RAM, I get about half the render time when I go from 4-16 GB. 8 is perfectly fine though, go with the 8 GB.
