Hi,

Can you explain exactly what is bottlenecking from what i've read it's the gpu that's too good for the rest of the system and the cpu cannot deliver what the gpu fully needs. Is there other applicable way for bottlenecking or is it only a videocard vs cpu thing?

And how can you tell if a system will bottleneck? General knowledge, experience or some crazy ass equation Einstein wrote down in a lunch break? :p

My system will be a E6600(or better depending what's the price/value ratio when i'll buy) with either SLI 8800GTX or a Crossfire with the new R600 that someday ATI will launch(i hope its before Vista service pack 2 ;).... knowing them.. wouldn't be suprised lol). It will be to play games at 1920*1200 and planning to keep it a while..

So for that supposition of a computer, will it bottleneck? And like i ask earlier, can you give more than just the answer, i'd like to know own to know :confused: lol

thanks!
 
You wont have to worry about CPU vs GPU bottlenecking...More importantly is getting the RAM and CPU FSB to match. In your case both your cpu and gpu will be top of the line.

In the case of the E6600: it has a 1066MHz FSB...so to get the most out of the system you would want to buy a motherboard that supports the full speed of the bus with complimentary RAM speed. Finding suitable RAM is more of a challenge because it seems the current trend toward a "standard" is at DDR2 800 (PC2 6400) since there are still several mobo companies that don't support the 1066 speed. But you can definitely find them...if you get the speed of the cpu fsb and ram speed to match you shouldn't have a problem with bottlenecking...but it will be an expensive rig.
 
I saw an indepth test on bottlenecking with core 2 duo's and 8800gtx's, cant remember which site it was now.
Basically an overclocked c2d managed to catch up with an 8800gtx at around 3.4 - 3.5 ghz. Anything higher and performance stayed the same until overclocking the graphics card and performance started to rise again.

ok thanks, but how do you guys know it will bottleneck? with the bus speed like someone mentioned earlier?
