So at a bit of a crossroad. I'm doing a lot of heavy computing for mostly long periods of time and occasionally sporadically. And i came here to get your opinions on which upgrade to go with either a

2(2 x 4GB pc5300 DDR2 FB-DIMM) or 2(2 x 4GB pc6400 DDR2){also a 4 x 4GB}

which one outweighs the other FB-DIMM or the higher 6400?

also looking at newegg any suggestions on a certain brand?

my setup is the following according to crucialscan

# Maximum Memory Capacity: 16384MB
# Currently Installed Memory: 8GB
# Available Memory Slots: 0
# Total Memory Slots: 4
# Dual Channel Support: Yes
# CPU Manufacturer: GenuineIntel
# CPU Family: Intel(R) Core(TM)2 Quad CPU Q9550 @ 2.83GHz CPU
# CPU Speed: 2826 MHz

You didn't say what motherboard you have. Many Core2 motherboards cannot use FB memory. It's a server thing, I think.

Look up the part number of the memory that is already in it.

Also check the QVL for the motherboard.

im pretty sure it cannot use FB memory.

sorry for the delayed response but the motherboard really doesnt have a name its a Dell T3400 motherboard im pretty sure they all use the same motherboard...

part number ill update later but it has 4 2GB DDR PC2-6400

i was thinking of getting either one of the two ITS NOT EEC
