No. If you are not going to use a 64-bit windows operating system, you won't be able to use more than ~3.5GB of RAM. The 64-bit versions will use all 8GB.
-- You may want to get a WD Black HDD; they have 5-year warranties. And if I recall correctly the Greens spin at 5400 RPM, while the Blacks spin at 7200 RPM.
-- Your PSU is quite powerful; you should be able to run your system with 500W-600W.

Like treeFrog07 said unless you run 64bit Windows 7 you don't need to worry about it. The real bottleneck will be your HDD. You can have all the CPU and RAM power you want but you can only go as fast as you can retrieve the data from the hard drive.

Going along with treeFrog07 you should definitely downsize your PSU. 1300 is extreme overkill!! Unless you are running quad SLI with a bank of HDD's you can easily get by with ~600w.

A great solution would be to downgrade the PSU and forget the traditional HDD. Take that money and buy either a small SSD for OS and a game or two along with ~1tb HDD or get the best of both worlds with a hybrid hard drive.

Not sure of you main purpose for the machine but if it is gaming, and judging by your selected video card I'm sure it is, you could also save some cash and get the i5 instead of the i7. Gaming isn't nearly as demanding fo the CPU as hard drive and graphically demanding.

i want to be able to run al my stuff if all my stuff needs maximum wattage, and i want some buffer wattage. and i dont want to have to buy a new psu when ill need 2 7990's to keep up with gaming, and its 400w max for 1 7990, and watt calculator says i need 350w max 4 the system im getting with no v-card's. that means 800w 4 the v-cards and + 350w for the system thats 1150w for the whole thing eventually, and the psu wont use extra wattage just because it can, so ive got enough wattage and a 150w buffer.
