Probably not with that Q6600 CPU. What's the +12V rating on the PSU?

Since you're already running that GT240 you can probably squeak by with a 5670.
Why you'd want to upgrade from GT 240 to HD 5670? They're pretty close in power requirements AND performance. So close, in fact, you might not even notice the difference.

It is almost paralleling going from GT240 to HD5670. There is only about 10% performance difference.

That would depend on the type of PSU you have, and what it's +12v rating is.

Officially, no, the Radeon HD5670 Requires a 400-Watt or greater PSU.

However, the wattage they list takes into account crappy PSUs that many boxed PC's have.

Also, keep in mind that the 400W requirement takes into account your whole system, the card alone does not need 400W.

So, to wrap it up, yes and no, list your PSU and it's ratings, and we can go from there.

if you can run the GT240, you can run the ATI 5670. Why would you make the switch though? As far as graphics go, both cards are fairly equal.

With all due respect, and to make a correction to your post, the GT240 requires 300W , which he has, the HD5670 requires 400W minimum, but as I said earlier, depends on the 12 volt rails, and the quality of the PSU itself

with all due respect to your lack of knowledge, the 5670 can require a 800w PSU and the GT240 can require a 200w PSU for all any knowledgeable person cares.

The fact is one card tops out at 62w while the other 76w so ATI and Nvidia can post requirements of any number they care to; the only thing that holds water are actual tests.

Both cards will work on any 300w PSU not named "ACME"

Tom's power review
http://www.tomshardware.com/reviews/radeon-hd-5670,2533...

both cards in a top end system under 300w total during load, by 50w
http://www.techspot.com/review/240-ati-radeon-hd-5670/p...

different system, total load system dead even with both cards at under 200w!
http://www.techspot.com/review/240-ati-radeon-hd-5670/p...

both cards are dead even in power at load, both systems are under 200w

Easy there, I wasn't wanting to get into a contest to see who was right, but despite charts, manufacturers requirments are manufacturers requirements and the simple fact is, that wattage hardly matters when it comes to a PSU, it could say 1200w but if it doesn't have sufficient amps to run the card itself then it's going to flake out. So, returning to my previous point, all that really matters is the quality of the PSU itself, and if he had posted the specs in the first place, I wouldn't be responding to your rather disrespectful comment about my "lack of knowledge".
