My GT could get to 400/1100 , not quite Ultra speeds but darn close.
My 6800 Vanilla could get to around 390 on the core and 1000 on the ram.
So the OCs I got>>
Ultra 15mhz core /40mhz ram
GT 50mhz core/100mhz ram
Vanilla 65mhz core/300mhz ram!
All told and looking back now there is not doubt the vanilla was the best bang for the buck @ $225 OTD.
In terms of performance gains going from the vanilla to the GT left something to be desired hence why I upgraded to the Ultra. Going from a Vanilla to an Ultra is a nice boost though...but it comes at a cost.
Its obvious that the Ultra is truely the ultimate platform for the NV45 as it is extracting pretty much all this chip can offer.
It really comes down to this for me...my Ultra runs stock faster then my highest GT OC and it does it 10C cooler. Aftermarket cooling to drop it 10C would run at least $30 and could run more.
