Is my 4890 being bottlenecked by my Q6600 2.4ghz (nonoverclocked) processor? Also running 8gigs of DDR2 6400 ram.

I don't think so, no.

Ah ok because I didn't really notice any significant increase in performance from my 8800gts

Well there's definitely a huge gap between the cards. Care to try overclocking about 400mhz?

yes it is bottlenecked...at stock 2.4 ghz.....most games still donot use more then 2 cores efficiently and rely mostly on speed vs number of cores...u can however pretty safely overclock that particular processor to around 3.0 - 3.2 ghz and even 3.6 depending on your other system specs.... at those speeds it will be a much better match to a fast card like the 4890..u can even run a benchmark like 3dmark 06 before and after the overclock to see if its worth it

I would somewhat dissagree and say that your q66 is somewhat bottlenecking your 4890. Take a look at the charts in the building a balanced gaming pc article:

http://www.tomshardware.co.uk/build-balanced-platform,r...

About half of the games in there are able to take advantage of 4 cores and the other half do not. those games that only support up to 2 cores saw a major boost from 2.8ghz to 3.0ghz. If you are able to overclock your q66 and unlock some extra performacne, if not then you wont miss that much, it also depends on which games you play aswell.

Well the only game I play is WoW and I don't think it even uses all 4 cores

in that case am not sure why you had the need to upgrade from a 8800 gts in the first place..unless u play on 2560 resolution on a 30 inch monitor, even then WoW is so easy on graphics card i think the 8800 gts would still have suffice

edit. i see you have a 22 inch monitor, honestly I would'nt have upgraded to a 4890 for Wow on that resolution

Bottlenecking is when the GPU sends more information than the CPU can handle. Does the game's utilization of cores affect this?

Apparently it dose because in that link ive posted above going form a dual core 3.0ghz to a quad core 3.0ghz yields massive improvement in Farcry and grand theft auto just to name a few in that article.

Well right now to be honest I still get a decent amount of spike lag in WoW. Especially when I raid or enter a populated city like Dalaran. I am currently getting 30-50 FPS in places like Dalaran (Highly populated place).

That spike could be due to your internet connection. Ya, those cities can be a pain sometimes on the most populated servers.

actually i would like to correct you...bottlenecking is when the GPU is waiting or starved for more data to be processed but the CPU cannot keep up because its slow and cannot feed the data any faster to the GPU...so if the CPU has more arms (cores) then obviously it can keep up with the demand more easily....but unfortunately a lot of apps and games do not efficiently utilize the extra cores (more then two ) on a CPU, but the condition is changing pretty fast and newer softwares and games are multi core supportive.

I agree with paperfox about the internet connection, that could be a reason ..... but like i said before WoW is more dependent on core speed as compared to the number of cores on a cpu..
