Is my CPU fast enough for a gtx 580?

Hello! So here's my question. I've always wondered as far as upgrading, when cramming a new card in your rig is a waste of $. I want a GTX 580, but, I'm wondering if the rest of my rig will hold it back. I have a intel quad @ 2.44ghz, 8gb of ddr2, on a ASUS P5NE-SLI board. Currently with two 8800gts 640. Any info would be a big help!

I'll get you the cpu in a sec... And just wondering why should I need to overclock it? And I run 1920x1080. The old 8800's do a pretty good job actually.

Here we go...

Intel Quad Core Kentsfield 2.4Ghz Q6600 CPU
Asus P5N-E SLI nForce 650i SLI Socket 775 Motherbo

And here's the Ram...
Crucial Ballistix 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel

I have a 600 watt power supply... but I plan on stealing the one from the computer I built for my mom which is a 750.

Thanks again!

True... The thing is I am possibly looking at a down the road entire rig upgrade, but I'd like a boost in graphics now. So I was planning on buying th 580 now and then throwing it into a new righ down the road. The 570 is quite a bit cheaper though... I'd take the risk to push the cpu too.

Well my friend you just sold me! Thanks for all the input! I find after owning a computer for three years it may be best to stay away from browsing newegg so long as it can still handle my games... But I broke down at work...
