I currently have a ATI 512 128bit 4670. Pentium 4 3.0 GHz/2M/800 (I have a Intel Pentium D 945 3.4GHZ/4M/800 SL9QQ in my closet I might put on, tell me if that would make a difference if I install it.) The PSU I have is this 400 Watt made by Corsair this link is at the bottom of this post. I usually get low frames when playing WoW in intense areas (Like Raids and Battle grounds, can be up to 40 players playing). Would putting in that CPU help alone without getting a new graphics card. I was thinking that the 5770 ATI is the best card, but I am not too sure and that or the best brand. I am open to any suggestions. I am using a Dell Dimension e510. The Main question is, what is the best graphics card for my PSU. I can worry about the PSU and my system later.

An HD5770 would be a good choice for the PSU but a poor choice for the processor, even if you swap in the Pentium D. Just put the processor in, it actually should help a lot. Your current card is a good match for it. Worry about a new card when you are ready to upgrade the motherboard/processor.

even though that is lower than the recommended power supply for 5770's im pretty sure you will be able to run it smoothly. at that price its probably better than anything nvidia has to offer without having to bump up your psu.

I honestly cannot straighten out what you are trying to say, can you clear it up for. Sorry about that.
 
A Pentium 4 and Pentium D will both bottleneck a 5770, because those CPUs are too weak to use the 5770 to its potential. (the 5770 is much more powerful than the 4670 and will require a good processor/CPU to use it to its potential)

WoW is fairly CPU intensive, so a Pentium D will be an improvement over the Pentium 4. The Pentium D is a good match with your current ATI 4670 graphics card.

All right, so the Pentium D processor will help my improvement with my Graphics Card right now, but it the Pentium D with a 5770 will not give that much of an improvement over the Pentium D with a 4670
