I have built computers before but others have always picked the parts for me. This is the first time I have picked the parts and I need some advice. Will this work? Should I remove, add, or replace something?: All items are from new egg

The 750W PSU can handle two GTX 260W cards, not ideally but it can do it. No way it can take 3 cards. That means 750i is enough, you don't need 790i or 3 PCI-E x16 slots.
Check out the WD6401AALS disk too.
I don't buy Sony in any color shape or form. You can buy a good DVD burner from somebody who doesn't ship spyware and rootkits with their products, you know, like Samsung or LG.
Thank you so much for your help. Here is what I changed my computer to. Let me know what you think. Also all these parts will work together correct. Do you think I should buy 8gigs of RAM or is $4 enough. Also do you think this case will work.

For best results, add Vista Home Premium 64-bit OEM ($100 at newegg). With XP you wouldn't get DirectX 10. With a 32-bit operating system you'd see about 3 GB of your RAM, even less with two video cards.
Between 4GB and 8GB of RAM...
If you have a 32-bit OS buy only 4GB because anything more will not be accessible. You can still install 8GB, you just won't see most of it.
If you use the PC for work too, and that work involves large files (Photoshop, video editing, databases, Visual Studio, etc.) get 8GB.
If in doubt after all this, get 8GB. The difference is only $50 after all. If you discover next year that you need more RAM it might be hard to find the exact same model again, and mixing models can cause instability.
