Anyone VOLTMOD a 7800GS yet?

[BeyondSciFi]

Im in the market for a new AGP card for my PC and I was wondering if anyone here has one and volt modded it yet. This is what I know about the card so far. Please correct me if anything is wrong.

Stock Nvidia 7800GS Specs:

Core: 375 mhz (Can do 480Mhhz at stock volts)
Mem: 1200 mhz (Can do around 1400Mhz at stock volts)
Frame Buffer: 256mb on 256bit interface
ROPs: 8
Pixel Processors: 16 (Fillrate: 6000 MP/s but can only display 3000MP/s)
Texture Processors: 16 (Fillrate: 6000 MT/s)
Z units: 16?
Vertex Units: 5 (468.75 MT/s)

3d Mark 05: 5300 (+/- 300 Depending on system) (@ 375/1200)
3d Mark 05: 6500 (+/- 300 Depending on system) (@ 480/1400)
3d Mark 05: XXXX with volt mod?

This core SHOULD be able to do over 600mhz maybe over 700mhz? I mean the 6800GS had 12 ROPs and it could do over 600 mhz voltmodded. What are your guys opinions on this?
