Will a E8400 (OCed) Bottlenext SLI

Wondering If a OCed e8400 (3.8-4ghz) would bottleneck a_______ and if so how much.
1. 260 GTX SLI
2. 9800 GTX SLI
3. 295 GTX

Hoping someone with experience with the e8400 and multi-gpu setups could pitch in!

Thanks

Is there any CPU that won't bottle neck 295 GTX at max res?

Anyway depends on what games you're playing and res.

For the most part, no!, i would say that the E8400 @ 3.6 or greater is the sweet spot and most setups will not have a bottleneck effect, save for the insane SLI or Xfire setups (295 GTX SLI, and i'm not even sure there would be too much of a bottleneck here either). As Sedaine said, it might differ between games/resolutions, but all in all, you shouldn't see a bottleneck, that is still a great CPU for today's standards.

To put it simply, i have an E8400 OC'd to 3.6 and 2 X 4870's in Xfire, through all my testing and games, i have not noticed a bottleneck where i would say that the Xfire setup should be working better...

In the NVidia world, I believe the PhysX software is supposed to assist with a less than comparable CPU by taking allowing the GPU to take over some if not most of the calculations to increase overall gaming/multimedia performance.

If i'm not mistaken, I believe I heard a rumor that ATI was supposed to if not already have a PhysX type of solution for there cards as well.

Forgot to mention what Res, Im running at 1680x1050 or sometimes running in windowed mode at 1440x900

Well unless this is something recent, I dono. I had MAJOR bottleneck issues with (along with a friend with the same setup) when I was running a AMD 4200 x2 and I saw a giant leap when I upgraded to my e8400, almost all my games saw a 60%-100% increase, with the same graphics card (8800gt)

There was a setting in the nvidia control panel somewhere called "Maximum pre-rendered frames" or something similar that helped with this.

I mean I understand that a CPU unless its top of the end will bottleneck a setup somewhat, but what type of numbers are we talking about?

1. 260 GTX SLI = a little (fairly insignificant) bottleneck

2. 9800 GTX SLI = almost no bottleneck

3. 295 GTX = basically the same as 2x OCed GTX260s

GTX260, HD4870, HD4830

Depends on the game but i mean even if there is one it would probably be barly

"Is there any CPU that won't bottle neck 295 GTX at max res? "

actually, as you raise the resolution, you have less of a chance of being bottlenecked by the cpu. it puts more workload on the on the gpu without putting anymore workload on the cpu. so, basically, if your cpu is the bottleneck, theoretically, there is a point in resolution where the cpu is no longer the limiting factor, but the gpu is.

Then you don't need SLi. Just a single GPU like GTX260 216 will do.

And that's all I plan on running for the next 6 months, Once games need a little more then just 1 260 gtx, Il go SLI

I was running a SLI 9800GTX+ with a 3.6ghz E6850 and i can tell that my FPS in games tha work with SLI was awesome. ( 1680x1050 )

COD4 and CODwaw completely maxed and still 60fps steady (vsync on = 60fps )
Crysis was also on HIGH settings and 4x AA for a 40-50fps.

3Dmark06:
SLI GTX+ with E6850 @ 3.6 : 16900 (on P5N32e-sli plus
GTX285 with E6850 @ 3.6 : 16000 (on P5Q)
GTX285 with Q9550 @ 3.74 : 19619 (on P5Q)

Only GTA4 made me change my setup to a Single GPU cause it dont support SLI and i love the game ...

So as few told. Depand on games you play. If they support SLI, Make yourself a favor and buy 2 GTX+ or 2 GTX260. If they dont support SLI ill suggest a GTX285 ...

Here's what I think:

For single GPU solutions, be it a GTX 295 or whatever, there is no way a E8400 will bottleneck the card.

If you want to go Multi-GPU, the case changes a little.

With regular SLI/CF, an E8400 may be a bottleneck, but utterly insignificant. You would still be good.

However, if you wanna go TRI-SLI or higher, that's where core i7 really shines.

But in my humble and honest opinion, I would never go multi-GPU... with a good single GPU you're ready to eat any game alive with that CPU.

I agree.

Q9550 ( or any E8xxx ) paired with a GTX285 can eat pretty much anything. You just need to buy a good Air cooling ( 50$ ) and your good to Hit 4.0+ with a Duo and maybe 4.0 with a quad.

I hope you just turned one of your cards off when playing the game, and didn't sell the second one just for that ! :ouch:

To all of you, Thanks. Hopefully I will be getting a More beefy card then my 8800gt!

I applyed for trade-up with BFG for the GTX285 vs GTX+. And since i have a P5Q that dont have 2 PCI-16, yes i sold my second card to a friend. I just dont need a second card with the GTX285.........
