What memory to buy for maximum performance

[Flankercom]

I've been told that I can't fill up all four of my slots with 1066 ddr2 ram so what should i do buy 4 800 or buy another set of 1066 as 1 of my 2 sticks isn't passing memory diagnostic test. I would like to fill my motherboard/CPU's potential for no more than 250 give or take 20 unless theres a steal of a buy. any links and suggestions are welcome thank you.

CPU:Black edition Phenom II Deneb 965 Quadcore 3.4 w/Corsair H50 liquid cooler
MB:MSI K9N2 Diamond
GPU:Nvidia geforce fermi 480 sc
Ram:Crucial x2 2gb sticks 1066MHZ (4 gigs)
Case:Coolermaster HAF 932 fullsize (I LOVE IT)
Powersupply:Kingwin 800watt modular
OS:Windows 7 64bit home basic

I'd just buy two sticks of DDR2 1066MHz, otherwise four sticks of DDR2 800MHz. Really though, I'd say 4GB is enough if you're planning to get 2x2GB kit - 8GB is overkill for anything except relatively heavy video editing and other RAM intensive applications.
