Hi, just looking for a bit of advice as I am building pc for a mate. I have got two 8800gt's to run sli from another mate for his build but i am using the p5n32 sli se motherboard which is struggling to overclock the cpu to any great length. The cpu is an intel e6600 duel core and the max I can push it with this board is 2.9ghz.

The question is would it be worthwhile buying a cpu such as the E5300 which has an 800fsb, thus a higher multiplier. I know that this will likely be better overall despite less l2 cache as the motherboard is limiting the fsb overclock, however with this cpu is it likely to get much higher than 3ghz? I thought because the fsb reaches 322 would i be right in thinking I could expect 3.5ghz+ with the x13 multi of the 5300? This is my friends first pc so i really want him to get the most out of it.
Any opinions would be appreciated thanks :)
 
E6600 is almost deffinatly going to be the better chip unless you can get a significantly higher overlock.

2.9gig on an E6600 is enough to push 8800GT SLI capably for gaming tho you won't see the full potential in benchmarks - but it won't be significantly held back either.
 
Thanks, I shall do some game benchmarks like crysis etc and compare them with other 8800 sli users to see what the difference is. But for what its worth a cheap and chearfull cpu like that capable of reaching almost 4ghz would surely thrash the e6600 at 2.9 even in games too? Especially since he will be using 1280x1024.
 
For something like crysis you probably won't see much difference from a faster CPU. E6600 @ 3gig is probably going to compare quite well against a E5300 at 3.4-3.5gig.
 
Ok so i ran the crysis bench at 1280x1024 and got these results:

dx10 high= avg 44fps
dx9 high=avg 48fps
dx10 very high= avg 33fps

I have no idea what 2 gt's should be hitting. This is with cpu at 2.93 and cards at stock. Can anyone tell me if this is ok for this setup? or if anyone has any usefull comparisons that be great.
