Overclock video cards

[Difolo]

Well I've been trying to get my hands on one of eVGA's 7900 Gtx superclocked cards with no luck. Every place I find is out of stock and on backorder, its really driving me insane. So I read an article about downloading some program and it is actually quite simple to overclock the card so then I began to think about doing it myself.

The two cards can be seen here:

Superclock: http://www.evga.com/products/moreinfo.asp?pn=512-P2-N575-AX&family=22

Regular:

So my overall question would be, are the heatsinks on both of these products the same? Therefore allowing me to buy the regular and bring it up to the superclocked speed. The difference is only 50Mhz on the core and 160Mhz on the memory. Also how hard would such a change as this be?

They look the same to me.

They are the same. Only the BIOS is different and the card is tested to work fine at high speeds.

So overall how hard would it be to overclock it? Also, I cant even find the regular now, everyone is out of stock!

All you have to do is download a program like rivatuner or coolbits and change the clock settings. The card should easily get to the "superclocked" card.
