So at high, a 6970 is looking at ~36fps.

With CFX, with just 66% scaling you'd be at 60fps (considering 100% scaling would be 72fps)

So running at high would give you a good enough overhead to maintain that 60fps with occasional acceptable drops in really heavy scenes.

So that's actually pretty good, High look really nice and would compete against the next gen consoles (running at 720p/900p)

at 1440p on ultra with my CF 6950 max I was getting was mid 50's fps. Set to low setting I was getting 100+ fps

So for multiplayer, apparently the CPU really bottlenecks. Damn. Well my 2400 isn't even on that chart, so it's probably pretty bad. (Lower than i5-2500K). A 30-40 FPS drop isn't really an acceptable margin there haha.

Your 2400K should be placed just above the 8350 OC to 5GHz on that chart by logic alone.. Its completely useless to change that CPU if you are on a budget If we note that you said you are NOT playing at ultra the difference will be even less noticeable (lesser physics effects on CPU etc) I wouldn't consider the 780 or 290x as they really perform much better at higher resolutions and wont be doing their maximum when another cheaper card can get you the same performance at your resolution. I'd totally reconsider the GPU solution and leave that CPU alone.

HUH *** people !? We don't get a product unless we can get it to run at it's maximum capabilities ?! So you are telling me I shouldnt get an unlocked CPU if i cant run it under phase 24/7 ? Or I shouldn't get a discrete GPU at all whatsoever if I don't have the CPU to make it run at it's utmost possible performance ?! This is just ridiculous and insulting to anyone who ever tried to be impartial or make sense on the site. Go ahead and waste your OWN $ if you care for your E-Peen and stupid arguments, but misinforming people for the sake of an argument is lowly.

Just for classification, it's a i5-2400, (no K version)

My CPU was originally a 2400, then a 2550k, now a 3770k.

One thing I remember doing with my 2400 was "limited overclocking"

You can force the boost clock, (3.8ghz-3.9ghz if I remember correctly) across all cores 24/7. Make sure you have a aftermarket CPU cooler though or it'll fry fast

We will just forget about Mantle for AMD 7000 and R series...

He'd have to wait another 2 months to see how it really affects anything.

Though if he goes AMD, he'll have to wait anyways for a good card to be released

Ehh, not really. The 290x is better at higher resolutions, yes. But not at lower resolutions, you're correct.

However, the 780 outperforms the 290x at resolutions closer to mine. Keep in mind, I'm running a lot more pixels than normal 1080 (since my monitor is 2560x1080). And at these resolutions, the 780 is seeing about 20 FPS greater than the 770, and 30 FPS greater than the 7970. That's not "the same performance" at that resolution.

And I am interested in running at ultra, I'm not sure where you're seeing anything contrary to that.

You see those FPS differences in a BENCH setting with a high end CPU, not real world. Anyways, you're welcome for the insight, it was a pleasure.

sometimes you need plenty of overhead to maintain 60fps. Especially in BF4.

Walk around in a small hallway or aircraft carrier....no big deal, a 660 Ti could max it out. But the second there's smoke billowing out from tanks exploding on the vast horizon and drastic weather effects wreaking havok, that 660 Ti is going to be bent over the kitchen counter while the more expensive GPU's will maintain that nice, enjoyable, and uninterrupted 60fps fluidity.

Same principal applies to every visual setting and resolution.

whether or not all that is worth it though....that's up to the individual, their priorities, and their financial habits

and one with a 780

Knew it.An 8350 is slower than an i5-3570k even 5.00ghz vs 4.5ghz,just knew it.

@OP : Keep your i5-2400,it's a beast of processor still and will be for atleast another year.

The FPS numbers I quoted were from in-game performance in BF3. Maybe not perfectly applicable to BF4 and my system, but it's close enough.



Also, I have another question for everybody: can I expect the price of 780's to stay the same, go up, or go down anytime soon? Nvidia just did a price drop, but I'm worried that will make the cards sell out and then when they're back in-stock, be higher in price due to demand. I'd like to ideally wait until the R9 290 is benchmarked, and the aftermarket designs are released before I make a final decision, but not if I'll miss out on the sweet $540 deal on a HOF 780.
