[quote name='supadupacheap']Do NOT, under ANY circumstances buy that power supply and team it with any of those cards. It would be like owning a ferrari and driving it to the limit on bald tires.
Im not good with the numbers but I can say with relative certainty that that intel is going to be a poor match for these monster cards. Yes, it will run most likely but its a bad pairing and very wasteful of the top of a top of the line cards power.
As far as cooling you should be ok but you need to check. If you have a very boring off the shelf case, it may not have the fan and air movement needed to support such a heavy load card. Im always in favor of swaping out fans whenever doing a huge jump in video cards. There is no such thing as too much cooling.
Completely put the 6800 GT out of your mind if you cant drop $50 - $80 on a good power supply. Pretty much put ALL of these cards out of your mind if your budget cuts it THAT close.
You really need to tell us a lot more about your machine for us to make a better assesment. You see, the cpu works in tandium with the powersupply and the videocard to output those purdy pictures. The whole system is as good as its weakest link so to justify buying a supercard, you really need to have a damn good cpu and a solid, stable, high powered PSU. If not, best case you are spending money on a card you cant fully tap. Worst case, you turn your new 6800 GT into a pop tart.[/QUOTE]
Thank you for going into some details. I can afford to spend as much money as I want into my PC, it is just that I don't want to spend too much. My system as of now is:
AMD Athlon 3400+
512mb ram (i'll find out the exact kind of ram in a day or two)
FX5200
When I am done upgrading, this is what my system should look like:
AMD Athlon 3400+
1 gig ram
6800GT or 6800Ultra (explained below)
I am upgrading an HP desktop that is pretty new (6 months old) but I am assuming that the PSU won't be enough for any of these cards, and it is worth $50 extra to prevent artifacts and the possibility of burning the card. My main concern is that I spent money to get a 2-year warranty from MicroCenter, and if I upgrade the PC, I don't know if that will end the warranty. If that is the case, then I might not upgrade now. I am assuming that the 3400+ CPU will be enough to get very good performance from the card, and maybe this power supply will be enough for the card?

If not, I can spend
Lastly, I might want to go with this card since it is only $14 more, but is an open box. By getting this card, I don't need to worry about shipping costs, plus, I can pick it up from the store 10 minutes away from me with instore pickup, and I wouldn't be surprised if MicroCenter could install it for me for free since they have been great customer service wise, and I bought a $1000 PC, a $300 video card, and $120 worth of ram and a PSU.

Do you think I will need to buy cooling? Again, I will buy what I need to get the performance I want, but I don't want to spend more than I need to.
Thank you very much for helping me through this since I am just starting to get into the PC scene.
Thank you.
