i should have put that in my post, sorry... i do have a good psu antec 850w so i'm covered there. I was going to another store tomorrow to buy the processor / board / ram and using my current psu and drives..
i started thinking though with the extra card now, should i look more towards an i7 but if the i5 can push the cf to full then that's great. I'll probably try as you suggest, but i only have the one monitor right now and plan to buy the other two a month or 2 from now.
The i5 2500k will be able to handle it just fine even with more than one monitor. The i7 is way over kill and you will only use about 40% of at any given time. The i7 is more for doing hyper threading. But it to will handle the two cards.
If you do sell your card you can get the going price for it and make a little profit that is if you want to.
