Hey guys, I'm running a classic 500 on a k7m, clocked to 650, using afterburner gfd. I'm about to upgrade to a slot-a thunderbird. I'm going to use my same gfd on the T-bird. In sandra it says that the max processor speed supported is 800+, whatever that means. If the max speed is 800 I'll buy a 650 or 700 and bump it to 800, but if it'll go higher, i'll get the 900 and take that as far as I can. Anyone know how high I can go? Thanks in advance, you guys are a lot of help.
