I'm making a gaming computer right now, and wanted to know what was better (with gaming in mind)

Running a q6600 g0, dfi dk x38-t2rb (can handle 4x2GB for a total of 8GB), crossfire 2x 4870's.

Basically, I'm deciding whether i should get 4GB vs 8GB (of course i'll be running vista 64).

If I get 4GB, I will get 2x2GB set.
If I get 8GB, I will get 2 of 2x2GB sets OR a 4x2GB set.

I don't know much about memory so which set of RAM should I get. I know the q6600 runs 1066MHz FSB so running 1:1 ratio will require me to get pc8500 or 1600 MHz speed RAM.

Either that or do I get 800MHz rated RAM (I don't know why I would do this but I have read it in forums. Also, couldn't find any 4x2GB sets running at 1066 on newegg.).

I would greatly appreciate your opinions.

Hello aberchonbie,

My suggestion is to ask yourself how long are you going to keep the machine and what are you going to really use it for.

A few games are starting to take advantage of more memory - so is Vista. If it's not onerous to buy 8GB and the machine is going to last you three or four years... it's probably not a bad thing to do.

I've been at 4GB for a couple years now and will be replacing my machine. I intend to use it for gaming and for learning server stuff so I want to have 8GB (not to hard to find it for $400 or less).

the actual fsb of the q6600 isn't 1066, that is the quad pumped fsb. The actual FSB is 266 and the multiplier is 9 with equals the clock speed of 2.4GHz. How fast the ram will be running at 1:1 on default clocks is 266*2 = 533.

If you want to speed your ram up the you can change your divider to times 2 which would give you 533*2 = 1066 or overclock your system.

Regardless, unless you are planning on doing heavy overclocks or really want to set the divider to 2:1 to acheive 1066 memory speed, memory rated at 800MHz should be more then enough for you
