4Gb of 1333MHz or 8Gb of 1066MHz - Which is best

I confused the title - it was meant to say 4Gb of 1066 DDR2 or 8Gb of 800MHz DDR2 Ram (i got confused with ddr3 lol)

I have an Asus P5Qc Mobo with E8500 Cpu clocked to 4GHz

When i built the machine i installed 4Gb of 1066MHz Corsair XMS2 DDR2 Ram and this has been fine, but im thinking i want to increase this to 8Gb of DDR2.

Now the mobo i have has 4 slots for memory. These can be used in two ways;

4 slots for upto 800MHz memory and then just 2 slots for 1066MHz memory.

As i have 2 sticks of memory in the 1066MHz slots i have no room to increase from 4Gb to 8Gb - unless i can find two sticks of 4Gb memory to make 8, which i think will be really expensive. So the only other way is to use the other slots with slower memory. (im not able to combine 1066 and 800 memory either)

So my question is this, would i see more benefit from reducing my memory speed to 800MHz but increasing the amound to 8Gb??

At the moment due to my overclocking i can only get my corsair XMS2 to 1016MHz as i lose stability after this.

Thanks

Tom

i would go with the 8gb cheap memory personally, i dont find a small cahnge in speed changes performance, however doubleing the RAM will see a performance increase, depending what your computer does of course, wouldnt do much for an internet browsing machine only

Yeah i use this machine for flight simulator and i read on a forum that the recommendation is to have 8Gb of Ram even though fsx doesnt utilise that much. The idea being it gave the whole PC some breathing space rather than restricting things through 4Gb.

I may make a purchase next month.

If your playing flight sim then definately better to have 8gb, Dont forget flight sim can go over its reccomended RAM usage, and not only that but Windows will still need some, so yeah 8GB is better than 4 for this
