Hey guys.

I got myself a little issue that I just can't decide on.
Currently I have the following:
Intel Core2Due E8400 3.0Ghz running at 3.6Ghz
Gigabyte P35 D3SL motherboard
Asus GTX 460 1GB TOP
4GB DDR800 ram
Gigabyte Superb 550W (450W) PSU

I got the following from a good friend:
Intel Core2Extreme QX9650 3.0Ghz
Asus Maximus Extreme Motherboard
Asus Radeon 4870X2 (Dual gpu card)
Soundblaster Fatal1ty soundcard

I'm going to be taking the Asus motherboard, Core2Extreme and the Asus GTX460 for me and give the E8400 with the Gigabyte board and Asus 4870X2 to my wife.

All I still need is a case, power supply, ram and hard drive.
I have decided on the Coolermaster CM690 II Advanced case (R796.86)
I still don't know what power supply to get.
I can get a Raidmax 730W modular psu for R751.26.
The other brands just seem way too expensive.

Another issue is the ram. The Asus board uses DDR1333(but it seems to be overclock-able to 1600 and 2000)
I can get Trancend Value ram or Corsair value ram for a good price (R453.72 for 2x 4GB DDR1333)
Can the price increase of 100% for gaming ram be justified by 100% increase in gaming.

Unfortunately money is very tight or non existent.
So I come to you guys, my fellow gamers and pc enthusiast for your input and knowledge.

Thanks in advance.
