gaming wise

Overclock your 950. With good cooling 4.5 is realistic

I wouldn't advise using Intel's IGP for gaming excluding some early 2000's games that require a powerful CPU, such as SimCity 4. Even the i7's IGP is going to be a struggle.

Either get an AMD APU, or pay extra for a dedicated GPU to go with the i3.

Hmmm? Clock for clock, Nehalem to Sandy-Bridge gives a 10-15% boost. Then you get another 15-20% moving from SB to Haswell, without even considering whatever benefits AVX2 could bring in the near future.

~10% is a bad reason to upgrade from one generation to the next, but when you aggregate the numbers over three architectural revisions... there's really no reason for anyone around here to sit still.

A bloomfield clocked to 4.5Ghz is going to run games 3-5fps lower then a 4770K with one 680. I'm going to test a 4770K at 4.5 vs a bloomfield at 4.5 when haswell gets released using a pair of 660's. We'll see how well bloomfield stands up to 22nm

Lol nope, many many many games nowadays are still cpu limited.

Such as lots of strategy games ranging from Civilization to Total War series


The main issue isn't how much CPU power they need, it's how they use the CPU. A CPU heavy game is more forgiving if it supports six cores natively, such as Crysis 3 or the upcoming BF4, unless if you're running an i3 or lower. Your main issue is when the games only use two or one core but was built for a 6 GHz Skylake CPU.


Games that don't use four cores:

Any or most Source based games
Starcraft 2...
Skyrim...
Cities XL (uses only one core)...
Planetside 2...
Natural Selection 2 (maybe?)
Taxing flash based games (Mudandblood 2, a RTS flash game, chokes on my laptop's CPU before Team Fortress 2 does. Seriously.)

And other older games. I think the original Crysis also falls under this category.

You make a very valid point but I've never seen a 3770k tested against a 4.5ghz Bloomfield. I usually see Bloomfield tested at 3.2ghz and its not a fair comparison at that speed

yea guys you also have to realize that with the FIVR intel can control everything from multiplier to BCLk and even vcore, they have total control over OC, however the motherboard still is more important than ever. Now you need all BCLK dividers working well and memory multipliers all working well, but that isn't hard to do wink.gif

Psst. Intel calls it iVR

You guys here should read Enhanced BCLK Capabilities on page 22 of BJ13_AIOS003_100_ENGf.pdf which reads:

Fine: PCH output +/1 around frequency points 100MHz, 125MHZ and 167MHz.

Meaning that this 170.1 MHz is well within the 7% marker and thus is nothing special since this is not even 2%.
