My friend has this rig:

i5 750 cPU
8gb ram DDR3 1600mhz
Asus P7P55DLE Mobo
2 sapphire vapor-x 5870's Xfire
WD caviar green 1tb 7200rpm
corsair 850watt PSU
Cooling - Temps are great tested myself 22C cpu idle 28C GPu's idle

Will the 2x 5870's Bottleneck any of the other components?

I'm almost 100% sure the rig will be awsome and without issues however he seems to have a few doubts to weather the cpu can handle it.

To clear his mind could people post what they think?

Cheers,

Oli

Depends on the resolution he games at and the clockspeed of his CPU to be honest.

battlefield badcompany 2 is probably the most intense game he plays.

Stock 2.67 ghx on the CPU

I mean surely if the CPU was under too much stress it would be running a lot hotter? when hes gaming it never passes 55C.
 
I guarantee if he had that at 3.8-4 (where I would personally have it) it would be a lot hotter under full load, 2.67 is probably bottling that xfire setup somewhat.

If his cpu is running at a low temp surely its not struggling, hes only got a fan cooler aswell?

Can any one else comment on Hairybudda's comment.

Not true, sure temps are related to how much load there is on a processor it is also related to a lot of other things. Think about it, he ups the voltage that's gonna stress the power circuitry on the board, increasing ambient temps, this goes for everything else you tweak when you're overclocking too.

Lots of people have their i5s on air @ 4+, I wouldn't feel great crossfiring 5870s with my processor at stock, performance won't suck or anything I just feel he's not going to be getting everything he potentially could at a higher clockspeed.
 
As already mentioned, clock that i5 up to around 4Ghz, that would give a noticeable boost over stock speeds.
And for the largest bottleneck: Hard drive. It's the green version, it's going to be slow. Grab a Samsung F3 1TB instead, and a SSD would greatly reduce any bottle neck in the system. ;)
 
Ye my thoughts were that the HDD would have been the issue, thanks for the information. i'll get him to overclock his CPU or do it for him. See how that goes.
