Take a look:
CPU: Intel Core i5 750 2.66Ghz 8MB Cache
CPU FAN: Scythe Reeven 120 (RCCF1201SP)
Motherboard: Gigabyte GA-P55-US3L
PSU: Seasonic 620W Active PFC 80+ (S12II-620)
HDD: Samsung 1TB Sata II 32MB SpinPoint F3
GPU: Sapphire HD 5850 ToXic 1GB GDDR5
RAM: A-Data 2GB DDR3-1333 CL9 i5/AM3 x2 (maybe x4)
Case: Gigabyte 3D Mars Silver

Okay, to start off, I don't really know what I'm doing. I've tried to read about different parts and stuff to learn as much as I can, and I had people recommending to me different parts that would suit my needs, and I've tried my best.

So what ARE my needs, you ask?
A mid to high-end gaming machine with plenty of RAM for severe multitasking, with 1080P movies, multitab internet and prolonged photoshop and adobe premiere editing. Also, a quiet machine.
No need for a monitor or keyboard\mouse. I'm planning to add 2 IDE DVD-RWs and another SATA(1) HDD from my old machine, and perhaps an internal MMC reader. MY current monitor is a 22" with max resolution up to 1920X1080.

This is what I came up with. What worries me the most is how compatible the RAM is to the motherboard, and the PSU, which I literally have NO CLUE about, especially about how it will go with the graphic card's connectors needs (I've read the 5850 needs 2 6-pin connectors and the PSU i chose has one 6-pin and one 8-pin, but someone told me I can use the 8 pin as another 6 pin. Is that true?)
Anyway, If i got any part wrong, please feel free to choose another one for me, but at about the same price range of the original part,please.

thanx for the help.

Its all fine and I think this computer will do fine, but if I new your budget I could make you such a nice gaming build and possibly get you more bang for your buck through newegg with combo deals!

wow, so i actually got it right? not bad for a first time =] What about the 6-pin\8-pin question. can i really use the 8 pin as a second 6-pin?

The graphics card will come with a two molex to 6pin connector and you just hook those up to create a 6pin.

Do i HAVE to use 2 molex'es or can i use the one normal 6-pin from the PSU and one MOLEX converted 6-pin?

If you mean that your PSU has 1x 6-pin PCI-E and 1x 8-pin PCI-E then yes, the 8-pin can be used on the 6-pin.

Thanks for the answers. What about the CPU fan? I've read some reviews and supposedly it's very noisy at 100%. Any recommendations for a quieter one?

^the reviews on that very site say it's pretty loud.

I would go off of the dBA. I mean its all dependent on the heat in your room and the programs that are going to running and the duration of the PC.
