Intel E8400 vs. Intel Q8400

Hi! I know this is a bit dated but I still don;t ant to let go of my old motherboard and reinstall Windows so I am thinking of upgrading my Intel E8400 to Q8400 (I can get it at a bargain).

Thing is I'm not sure how much difference I will get on performance for Quad core optimized gaming since (new games). Games I play are:

Starcraft 2
The Witcher 2
COD Black Ops
Crysis 2

Among other things. Is the difference in FPS noticeable?

I am using a GTX460 and see a drop in framerate on these recent games (except Starcraft 2) but I feel I can push these games to higher settings if my CPU is a Quad Core. Am I right?

here use this for E8400 vs Q8400 (scroll to bottom for a couple gaming benchmarks): http://www.anandtech.com/bench/Product/89?vs=56
, there is not much difference between them in terms of gaming... actually the E8400 is probably better in most cases since it is at 3ghz and the Q8400 is 2.66

Seems to be more of a side grade than an upgrade to me, how much is it going to cost? If it's only a small amount and you can keep the option of going back to the E8400 then it might be worth doing just as an experiment if nothing else.

You'll get improvements in Crysis 2 and probably The Witcher 2 as well, but as for CoD and SC2, you will not see any improvements.

Crysis 2 I'm not so sure about and Witcher 2 I can't say because I don't have it.

In fact looking at the numbers for AMD CPUs, Crysis 2 can utilize 3 cores.

I was swapping around between the E8400 with 8800GT's and an i7 2600k with a pair of GTX560's and even on the E8400 rig my numbers were a lot higher than those on that chart.

Instead of the Q8400, looks like I'm getting a Q9550 for a few dollars more (roughly around USD 20). I would assume its a bigger improvement?

I forgot to mention I'm running Windows 7 32-bit with GTX460 nVidia with 4GB DDR2 RAM. I noticed a lot of my games are already lagging (with my E8400) especially if vSync and effects (SSAO, Shadow, smoke, Bloom, etc.) enabled so I assume that this is due to my dual core since Quad Core would most likely use different cores to render different graphics needed.

I'm also anticipating that the new COD MW3 would most likely be optimized for Quads already. Oh, forgot to mention that if I go DX11 on high settings, everything CRAWLS. Not sure if this is due to processor as well but I would assume it is so.

Tried Windows 7 64 bit but with my current rig I noticed a lot of applications are slower to open (Office, etc.) and I ran into a lot of incompatbitlity issues so I reinstalled to a 32-bit. (Added info just incase somebody will suggest going 64-Bit)

Oh and I'm just going to run stock and won't OC the processor. Don't know how to and though I can try, I don't want the burden of breaking it. : )

Let us know how it turns out.

I also forgot to add that since most PC games are designed to run on consoles as well, this is most likely the reason for the big crap that COD BO did on its launch, the 360 has 3 cores and the PS3 has more than 2 cores as well, probably the reason why most games are designed "to be optimized" for Quads and better. (Just my 2 cents). Still need your advise especially the ones who have experienced a rig like mine.

What will happen:

Intel Q9550 2.83Ghz (stock)
Gigabyte EP45-UD3L (latest Bios)
4Gb Memory DDR2 (Corsair)
MSI GTX460
Windows 7 32-Bit
22 Inch Monitor (1680x1050) Resolution

Is this rig going to be ok or better than with my e8400 running almost max settings and with games that are DX11 compatible?

I'm looking for benchmarks and I can;t find 'em for the newer games.

I never used my Q9550 rig for gaming so I can't really help you out with that one.

Yeah, I could always resell the Q9550 for the price I'm getting it so if it didn't give much improvements then it would probably be ok I'll just retain my e8400.

Got the Q9550 and all I can say is that this CPU is amazing! Very significant improvement on the games listed above.

Quad Core is the way to go these days.

also the Q9550 is alot better than the Q8400, so its not just the fact that it is a quad core chip,

anyways... good buy, enjoy!

Honestly as far as performance in games you may only see very slight improvements as most games use 2 or rarely 3 cores for the actual game. I would still upgrade to the Q8400 as dual core processors are beginning to get phased out of the market.

I don't know about benchmarks but the Q9550 has a very significant improvement in running games these days. Dual Core seems to bottleneck even with the older games like Battlefield 2 BC, Black Ops, Assassin's Creed 2, Borderlands, etc.

Major improvement on the latest games though especially The Witcher 2. I got from low to mid settings to high settings when I upgraded. GTA 4 is simply amazing with Quad core and my GTX 460. I can now go Extreme graphics settings on Crysis 2 without any hiccups, I can onky go on high settings on Core 2 Duo.

That's my take so that anybody who is looking to upgrade can make a decision when they see this post.

I was running Crysis 2 @ 'Extreme' on my e8400 rig without any hiccups. I was using a pair of 8800GT's in SLi and then a pair of GTX560's also in SLi, but still.

Hmmmm.... that was wierd, I felt some slowdown on mine even on very high settings on Crysis 2 but this is just GTX460 with no SLI on my e8400. Well have to request to close this thread apparently I sold my Q9550 for a higher price than how much I bought it and upgraded to i5 2500k and sold my GTX460 and got myself a GTX560 Ti. This will hold out until next year when GTX660 comes out hehe.
