Yeah definitely the 450 or x50 in general is entry level where as the x870 or now x970 would be high ends. Check the ccc over clocking section you can unlock the option to set the clocks for your cards through one of the buttons there including fan control.
The e 6300 shouldn't be a problem though with bottle necks maybe aging perhaps but try giving it a boost in speed through bios? What are your full specs Atm?
...but a GTS 450 is fater than an HD 3870, maybe than a HD 3870 X2 too. It depends from the generation of the GPU.
My specs are under my signature (2nd pc):
Core 2 Duo E6300 @1.86GHz
Asus P5LP-LE motherboard (locked, no way to overclock NOTHING, bios updated)
3 GB DDR2 Dual Channel
600W PSU
Windows 7 32bit SP1
and now... Radeon HD 4870 X2
Overclocking did nothing, the card is still locked at 500 MHz:

GPU 2: http://i50.tinypic.com/v6ep.png
I'm also encountering 3 more issues:
- I can hear a "beep" in the card when i try to use GPU-Z render test in fullscreen... However, here it seems that both GPUs are working here!
- WEI dropped by 7.2 (GTS 450) to 7.1... and that's why I'm thinking I'm using only 1 GPU...
- Card is working at PCI-Express x16 @2.0 since I have PCI Express x16 @1.1!!: http://i47.tinypic.com/1pe2yu.png
I'm using catalyst 12.6
And yes, I cleaned and removed all Nvidia drivers.
solved the frequency problems!
I enabled Catalyst AI on advanced settings!
Yeah generation of the cards can really boost a difference. I'm not really sure on the beeps but if the temps are good its more likely a load warning or something like that. Glad you manage to get it working. Cheers.
Load warning? The second GPU isn't used by 3D games...
I e-mailed AMD, they will send me a hotfix soon...
Solved:
I reinstalled Windows and now CrossfireX works! With Catalyst 8.12!
The card provides awesome performance :)
