Hey, thanks for the reply.
I'm really enjoying this card. I let the card run at stock settings for about a week or so before overclocking, right now I have it at 665 core / 1225 mem (stock: 648 core / 1188 mem). I can probably go higher but haven't tried it yet I figured I'd see how it handled this for awhile and make sure I don't see any artifacts or lockups over time and so far so good... I'll be playing with higher clocks today. I score around 14,300 in 3DMark Vantage performance with the current overclock as opposed to my 8800 GTS which scored around 7,700... a very nice boost
I downloaded some custom config for Crysis like you describe from somewhere (it's the one floating all over out there), is yours tweaked beyond that? If so feel free to post it and I'll check it out, the game definately has plenty of overhead to spare now
