I have a P5B Deluxe/WiFi too. I also have that exact same video card (it fits just fine even with the large heatsinks). Do you plan on overclocking? The reason I ask is because of your choice of memory. I suggest that you save yourself $100+ by getting DDR2-667, the DDR2-800 isn't worth the premium price at the moment. The RAM I went with is this:
It works great with the P5B Deluxe. It runs at DDR2-800 speed without any voltage increase (1.8V) at 4-4-4-12 timings. I've played around with overclocking and this RAM can take it (passes memtest86 and Prime95 torture test). If your dead set on the XMS memory, it will be just fine. I just wanted to let you know that you can get more for less.
The P5B Deluxe is the same just wihtout the WiFi so get it if you wont need the WiFi. This is a really good motherboard if you plan on going quad-core one day. Check for a BIOS update that will allow you do some more overclocking with that board.
Dont go with Corsair, but do go for DDR2 800, get anyone with 4-4-4-12 timings. This indicates that theyre using the same Micron chips as Corsair and therefore perform broadly the same.
The 7600GT is a poor card for this setup, it just doesnt add up to the rest. Unless youre planning on saving and getting a DX10 card as soon as they become avaible, get a 7900GT. The X1900XTX can be found at pretty sweet prices right now, and its top-notch performance that will last you a long while.
Take a look at the OCZ GameXstream series, IMO much better value and a better PSU overall. Quad 12v rails, high efficency, PFC etc...
I dont know about that "powercenter" youve picked but for that price you could get a voltage regulator (not just a supressor), ive been using voltage regulators since my first build and never had an overvoltage problem or something similar.
Ive never heard of Asus having trouble cooling their chipsets (much less in newer models) so idk if those extra fans are worth. You might wanna fill every avaible space for a fan in your case though.
not sure what type of machine this is, but for all the money your putting into the mobo/cpu your skimping on the graphics card...i guess you could be waiting for dx10, but its not just going to be a done deal when it gets here..
