BF3/4 64 player TDM rig AM3+?

post #1 of 8
Thread Starter 
Hey all,

I've become a pretty avid battlefielder over the last year or so, finally went out and purchased an Asus VG278HE 144Hz monitor the other day to get the smoothest performance in game. I play almost nothing BUT 64 man servers, a lot of that on tight TDM maps - where I admin a few local servers, and have to now look at investing a little more in my base rig to make the most of the new screen.

I'm currently running a 7950 with an I5 2550K (with my cooling I could prob OC it to 4.5-4.8).. I was initially planning to grab another 7950 (especially now there's hope of better crossfire support from AMD since the release of the 13.8 beta's), but that would have required a new mobo as well. Now I'm scratching my head, since those tight 64 man maps are also quite CPU hungry, should I bite the bullet and grab a AM3+ mb and perhaps an fx-8350?? Will the 8 cores give better performance than 4 on crowded maps?

I've been reading a bit about frostbite's scaling, and it seems that on those more heavily populated servers - while gpu power is important for maximum frame rates and gfx settings, CPU power is almost as crucial, boosting minimum frame rates - thus making better use of the 144hz screen.

Having dumped a reasonable sum on my home setup (built a file server and my partner's new rig) I'm not too keen on the idea of grabbing a 6 core I7 due to the expense ($600+). But since frostbite seems to make full use of the extra cores (especially in 64 play maps) I could probably justify the $400 or so for an AM3+ mobo and cpu...

So do I just grab a crossfire Z77 mobo and stick with the I5, or should I invest the extra couple of hundred and throw an 8 core AM3+ in the mix? In my mind, this is becoming a particularly attractive option with the upcoming "AMD optimised" BF4, but I'm not a technical pro by any stretch and I'd hate to be blowing cash as money is a little tight right now...

Oh, minimum framerate is probably more important to me than being able to run the game on ultra... I don't need it to be too pretty, I just want to be smooth...

Stick with the i5 or buy an i7 3770k to improve minimum FPS. Don't go AMD unless you already have a compatible AMD motherboard, it isn't worth it.

Buy a 2600k/3770k/4770k, my 1200/1650 CFX 7970s ran BF3 at around 60-70% usage @ 4.7ghz. I personally would go with whatever platform you can get cheapest if you are going to overclock, if you're not going to OC might as well get the the 4770k for the best stock performance.

One more side not since I saw you say you wanted to stay with your 2550k. I'm not sure you won't get bottle necked with two 7950s unless you're going to push your CPU to 5.0+ I never tested my 2500k with both of my cards, but I feel with how CPU intensive BF3 can be you might suffer a decent performance hit if you end up pushing your 7950s. Hopefully someone with your exact setup can give some insight.

Hmmm i guess i was a little confused thinking the 8 Bulldozer cores would outperform the current setup... After a few (more) hours or reading, it seems even a 4 core Intel cpu will flog an AMD equivalent... I suppose the next question would be, since I will be needing a new mobo anyway, should I be looking at 1155 or 1150?

Good lord, what ever happened to the good old days when you KNEW that Pentium 1 outperformed a Pentium 2, and that an i7 would outperform an i5... Now its all meddled with production processes - Ivy bridge and Sandy bridge are both 1155, whereas only a Haswell is 1150... My local stockist only has a half dozen 1155 mobos, but stock a good 30 1150's.. (that was confusing in itself!)

I'm getting too old.. frown.gif

Since i was looking at the AsRock Z77 Extreme4, I'll go with that for the moment, then when the cpu bottlenecks obviously (probably immediately) I'll look at throwing in a 3770 (or 3770k?)..

Thanks guys for the assistance! thumb.gif

i run bf3 ultra settings from a range of 50 to 100fps depending on map or server

You need to read a little more then as the 8350 and 3570k perform pretty much identically in Bf3 multiplayer. Having said this there is no reason to purchase Am3+ on a new build over the current similar priced I5 variants. There is currently no cpu that can push 2 x 7950 to 100% constant use in this game. A large % of the maps are poorly optimised. Hopefully Bf4 will be better for the cpu/gpu balance

1080 60Hz maybe but not 144Hz.

@op, just get an i7 and another 7950. crossfire is smooth in BF3 but you'll still give up MSAA. 2 instead of 4.

Don't use AA in FPS games, at least not multiplayer. It adds input lag.
